Good news. The PCB is finished. I will submit the data tonight at Eurocircuits. I will first make a few prototypes. Please contact me to experiment with me on the board. I am not that good in software, but the hardware is most of the times good the first time. Let's hope this is also good ;) There is a lot of hidden work when you see the design (assigning SerComs, making it almost compatible with the Arduino M0, fitting it in a housing, etc.). So sorry for the delay, but here it is....

A small line of solder mask is missing on the edges of the PCB. This is for ESD reasons. I will receive the PCBs around 10 August. I will make a few pcs right away. I ordered 5PCBs. So if you want a PCB, you can ask me. In return I ask you to make changes to the Arduino M0 sercom configuration, adapt the ENC28J60 library, adapt the SSD1306 source for this board, make certain IOs available in Arduino. So the main thing is to adapt the functions to the pinning of this board (reconfigure IO). Libraries for Ethernet, WiFi, BLE, USB, LCD, etc are available (maybe not working due to pinning).

The PCB data will be published here if the prototype PCB is good. You can make the PCB for personal use (gerbers will be included), but not for commercial use.
