Custom Arduino board

As I have been using different packages and platforms for DIY projects, I finally made my own board

Not my first attempt of, course, as I made many home made PCB’s.

The whole idea of this project is to have something made by professional, and a silk screen on top of the solder mask!

Here are examples of prototypes programmers I made.

So now, came the time to go JLCPCB !

I did not know what to expect, but it was made in 12hrs and I received super fast although coming from china.

The whole idea is to have a custom development board containing 2 AVR chips, an Atmega32U4 for the system with an HID compliant USB stack.

And an AtTiny24 to read a rotary encoder; both chips should communicate through SPI bus.

So once, I manage to make everything work and write the firmware, I’ll have a custom Macro Keyboard that I can use with different devices (even MIDI over USB).

Just super cool!

In parallel, I am actually building and testing the firmware on breadboards. And using an Arduino Micro.
