Information
The XNL Breadboard LessMess 1284, the XNL Breadboard LessMess328 and the XNL Easy Breadboard Crystal is a “family” of small boards which can make it a lot easier, faster and cleaner to setup several microcontroller on your breadboard directly.
With the LessMess328 and LessMess1284 you can eliminate the need to ‘manually’ place two 100nf capacitors on your breadboard. Obviously placing these two capacitors isn’t that much of a ‘hassle’, but it also eliminates the risk of capacitor leads shorting, it keeps your breadboard cleaner, and due to the printed pin-outs on the LessMess boards, you also instantly have ‘quick pin reference’ to the VCC, AREF and GND pins of the microcontroller on your breadboard.
The XNL LessMess boards ‘install’ a 100nf capacitor from VCC to GND and will install a 100nf Capacitor from AREF to GND.
both boards will come with a datasheet which also includes an assembly manual, schematics and license,
Recommended to combine
It is highly recommended to combine the XNL LessMess boards with the XNL Easy Breadboard Crystal, because when using them as a ‘set’ it will be even faster (and more stable) to setup a microcontroller on your breadboard.
Alternative Model
We also have an alternative version of this board which is for example compatible with the ATmega328, ATmega168, ATmega48 and ATmega88
Ordering Tip
Due to the small size of the XNL LessMess boards it might be cheaper to order them at a PCB Manufacturer/board-house which actually ‘bills per square inch‘ instead of a board-house which uses ‘fixed prices for all sizes up to a certain size’. These boards will (currently) be cheaper when ordered at OSHPark than when you would for example order them at JLCPCB. However, do keep in mind that shipping costs will also be added to your order though! So when you are ordering multiple boards at for example JLCPCB and just these at OSHPark, then it might actually still be cheaper to order these also from JLCPCB at the same time (due to combined shipping).

IMPORTANT
Do note that all sections/'chapters' bellow constitute the entire license and that they are 'interconnected'. This for example means that if there is a section about Closed Source/Binaries License, that this doesn't mean that the rest of the license doesn't to those binaries. It just means that that section is specifically aimed at those files, while the rest of the license (where applicable) is also 'in effect' for those binaries.
(Additional) License(s) in Project, Product or Download
This project, product, the files etc in this download/these download(s) contain (one or more additional) license(s).
When you download this project, product, files, download(s) etc, you agree that you will read the license(s) included in the download and it's files, projects, products etc and that you will delete 'the downloaded content' if you can't (or don't want to) agree to the included license(s).
These license(s) will most likely be present in one or more of the following ways:
- As license agreement/EULA window (in compiled software for example)
- As License 'embedded' into the documentation (like a datasheet for example)
- As additional license file which can be included into the Download (or archive file like a zip file).
- As as 'commented text' in source-code or as 'additional license file' in source code.
Don't worry, this license or these licenses will not be 'sneaky hidden' or hard to find, these licenses can be found in their expected or logical locations (as mentioned in the examples above).
Commercial Use Allowed
Commercial use of this project, product, it's files, download(s) etc is allowed, which means that you are allowed to use it for own financial gain, there could be however (additional) restrictions included in a license (or licenses) which is supplied (within) the project, product, download(s) etc which limits the extent of how (far/much) you are allowed to use it commercially. By using, downloading or otherwise using this project, product, it's files and/or download(s), you confirm that you will first check the supplied content/download(s) for additional licenses to see if there (additional) restrictions which limit the extend of the Commercial Use Allowed Permission Clause, before using it for commercial purposes in any way.
A project/product which for example does allow Commercial Use within your company or organization under certain (licensing) conditions but does not allow you to (re-)sell the project/product would be XEWA™. When you consult the XEWA™ License (which is provided with, and build-into XEWA™), you will find this (additional) license information and/or limitations in the 'included license'.
If the project, product, code, files etc don't include any (additional) license(s), then you are allowed to use this project, product, it's files, download(s) etc, in any possible way for commercial use (including (re-)selling it. If there however is an (additional) license included with the project, product, it's files or download(s) you hereby agree that you will also read that license and accept that license prior to using the project, product or file(s), and that you will refrain from using the obtained 'content' in any way if you can't (or don't want to) agree to the (additionally) included license(s).
IMPORTANT NOTE:
Make sure that you also consult the rest of the license(s) to see if clauses/rules like Attribution Required or ShareAlike for example apply, because even if you are allowed to use the product for any type of commercial use, it could still be that attribution required or ShareAlike 'rules' apply.
ShareAlike
Our ShareAlike Clause means that if you are are for example allowed to share/redistribute modified versions of this project, product, it's files, download(s) etc, that you have to share it under the same conditions as this original work.
Some examples of what this means for you:
- If the rest of the license for example permits you to modify and then redistribute your own 'adaption/version' of this project, product, it's files etc, you would then need to comply with the following 'rules':
- If this original project, product, it's files or download(s) etc are 'open-source' (provide source code/files with it), then your modified version can only be published/redistributed if you also supply your (adapted/modified) source code along with it.
- This also means that you are not allowed to take a project, product etc with the 'ShareAlike Clause' in it's license from our website, modify it and then start redistributing or even selling it as 'closed-source' only.
- You are not allowed to 'remove' clauses or 'rules' from the original license (just to give an example: You are not allowed to remove the 'Attribution Required' or the 'Commercial Use Not Allowed' clauses from your version/license).
- You are not allowed to restrict the original license with additional clauses and/or rules of your own.
We can understand it if some developers/creators put a lot of effort in 'upgrading' existing works, but that they would not like our (for example) 'keep open-source also open-source on redistribution rules', but all I/we can say about that is: Sorry, but that's the 'game of this license'. If you don't like it, then just create your own stuff from scratch 😉
The ShareAlike clause (obviously) also remains fully enforced if you decide to redistribute unaltered versions, and thus the same 'rules and examples' as shown above would apply, but to the unaltered version/re-distribution.

PCB Order Instructions
NOTE: Usually I would recommend JLCPCB as my personal favorite, but because these are quite small PCB’s, it might actually be cheaper to use OSHPark for example (just to mention one) due to the shipping costs and ‘default price’ per board (at JLCPCB) instead of paying per inch/cm.
This section explains the (recommended) ordering process and settings (at the PCB manufacturer) to order our circuit boards using our provided 'ready-to-use' Gerber (zip) files. We will first give a basic overview for the recommended PCB Manufacturer settings, so that the more experianced users can instantly find what they need, and after this 'settings overview' we will explain more in-depth how you can order our printed circuit boards (PCB's) using the files you can download for our projects, products and packages.
NOTE: The clickable links to JLCPCB are referral links, more information about this at the bottom of the page.
Recommended PCB Ordering Settings (Material, layers etc)
All our boards (unless otherwise stated) are designed for and should be ordered with the following settings:
(Base) Material: FR4
Layers: 2 Layer / Double-sided
PCB Thickness: 1.6mm
PCB Color: Choose whatever you like or stick to the 'official project/product color' 🙂
Outer Copper Weight: Use default of the website you're ordering (often 1oz).
When ordering from JLCPCB and using the zip file which has (JLCJLCJLCJLC) in it's name:
Remove Order Number: Click on [Specify a location]
How to use our files/downloads to order the circuit boards
To order the printed circuit board(s) included in this project, product or package you will first need to download and extract this project or product.
Our project and product folders will often contain several folders/directories, of which one of them should have a name similar to 'Gerber Files (For Ordering-Production)'. If the downloaded project or product only contains one printed circuit board (PCB) then you will often find two archives (zip files) within this folder.
One of these archives will have (JLCJLCJLCJLC) in it's name and the other won't, for example:
ProjectXNL.zip
ProjectXNL (JLCJLCJLCJLC).zip
NOTE: You will only need to use one of these files when ordering, not both. So please read along to find out how this works 🙂
My 'Gerber Files Folder' contains even more folders
If this is the case it just means that the project, product or package you have downloaded consists out of multiple circuit boards (or options/variations you can choose from), you should consult the documentation (or included text file(s) in these folders) of your project, product or package to find out which folder (or PCB's) you will need. Inside each folder for the different Printed Circuit Boards in the project, product or package we will still use the same 'file structure' where there will be two files per PCB (one having '(JLCJLCJLCJLC)' in it's name and the other doesn't).
My Gerber Files Folder only contains one zip file (per part/option)!
This is also a possibility, this just means that we did not created an additional 'Gerber file-set' with PCB's which have JLCJLCJLCJLC on them. We often choose to do this for boards which would be to small to actually place such texts, we will then just let it be up to JLCPB to place the production/batch numbers on them. So if there aren't additional zip files which have (JLCJLCJLCJLC) in their filename(s), then you should just use the zip file(s) which is present in the folder(s).
File difference explanation
- The one which has "(JLCJLCJLCJLC)" in it's file name will have JLCJLCJLCJLC printed on the circuit board.
- The one which does not have "(JLCJLCJLCJLC)" in it's name will not have JLCJLCJLCJLC printed on the circuit board.
Ordering anywhere else than JLCPCB
When you want to order anywhere else than on JLCPCB.com you should always just use the zip file which does not have (JLCJLCJLCJLC) in it's filename.
What does this JLCJLCJLCJLC on the PCB mean?
Well this 'piece of text' tells JLCPCB where they can/should place their (internal) manufacturing/production/batch numbers, which they use for handling your order internally. JLCPCB offers a free service where circuit board designers can specify where JLCPCB can place their 'internal batch/production numbers', this prevents issues where they would for example (accidentally) place these production/batch numbers on an ugly location and thus possibly ruin your 'precious silkscreen artwork' 🙂
Ordering from JLCPCB
When you do want to order at JLCPCB.com you have two options to choose from:
- Pay a bit extra on your order (currently around $1.54) and have JLCPCB remove their manufacturing/production code completely, in which case you should use the file which does not have (JLCJLCJLCJLC) in it's filename.
- Or instead use the file which does have (JLCJLCJLCJLC) in it's filename, in which JLCPCB will use the by us specified location to place the manufacturing/production/batch number(s). We will always (try to) place this text in the least noticeable location or where it would not 'mess' with the rest of our silkscreen design. To be extra clear: When using this option you will have a small 'batch number' printed on the location of your PCB's where we had placed the "JLCJLCJLCJLC marker", but it will save you a bit of money on your order.
IMPORTANT:
If you are ordering from JLCPCB and you are using the zip file which has (JLCJLCJLCJLC) in it's name, then you have to make sure that you search for the 'Remove Order Number' option when ordering your PCB and then select [Specify a location] at this option. Otherwise you might still end up with an 'factory batch number' on your PCB AND have the 'text' JLCJLCJLCJLC printed on it. So make sure that you select [Specify a location]
Price estimate at JLCPCB
Currently (at the time of writing this 'pre-configured order manual template') prices at JLCPCB per PCB Design are around 2$ to $4 if the board is 100x100mm or less, which will get you 5 copies of the board itself for this price. And if you order 10 of the same board you will often just have to pay $5 (so just $1 more for 5 extra boards). We use JLCPCB for nearly all our projects and products and we are very satisfied with their quality and production times. Ordering from JLCPCB is as simple as going to JLCPCB.com then 'drag-and-drop' your zip file (with the Gerber files) onto the page.

PCB Sponsor Update/Referal Link Information:
Since July 2024 JLCPCB is now sponsoring my projects, platform and YouTube channel, I'm very grateful for JLCPCB offering to sponsor me (they actually contacted me, I did not contacted them). Despite the fact that they are now sponsoring my/our projects, my opinion about them remains unchanged and will also state that my recommendation to use JLCPCB is 100% my own. If I would not have used (and loved) their service that much myself already I would not have accepted their offer either. The reason I accepted their sponsor offer is because I had already been using them for many years with great satisfaction.
If you click on the referral link I will NOT be able to see that you have clicked it (I will not get any user or order details from them), and neither would you pay more when using their link for example. Using the referal link does however support my projects, content and platform 🙂
You can also use JLCPCB for FR-4 boards up to 20 layers, Flex pcb's and assembly of your PCB's (meaning they will put the components on them for you, I personally haven't used the latter (yet) though).
