Hello, Arduino's are an amazing platform to make the first prototype electronics for a project or product, however there comes a time when the Arduino board may be getting in the way of advancing your prototype. Perhaps you have a very specific shape for your product, and you need the Arduino to fit inside, or perhaps you have lots of other electronics modules or circuits on a breadboard, and you want everything to be on a single custom Arduino, or perhaps custom shield. I can design and manufacture such custom boards for you! So, after I have discussed the functionality of the board system with you, this is what I will do: I will send 2 custom Arduino boards to you. I will also provide you with the digital design files, so that you can have these altered or changed in the future if you need. They will be made using standard software, so any good electronic engineer should be able to work on them in the future. In addition to the basic features of the Arduino, I can offer a range of other functionality. For example, if you would like your custom Arduino to have: For custom additions, please message me to discuss them before purchasing. If you have specific component in mind, maybe something you have used on a breadboard, then please let me know the part number and I'll have a look over the data sheet. If you have any questions, please get in touch. Regards, -Steve
