As the title says. Recently I was bored, so I casually drew an M61 core board. The size and pins are fully compatible with the ai-m61-32s-kit, and on this basis I brought out a USB port and an auto-download circuit. The project is on LCSC (Lichuang) EDA:

Physical demo:

This time, all the resistors, capacitors and LEDs I used are 0402 packages. The board carries a common-cathode RGB LED and a user LED. A jumper cap selects between USB and serial, and I used the specified 50x50 QR code for the customer number position.

Light an LED:

OK, this is just something I drew casually; there may be many non-standard places. If you don't like it, you can use mine as a reference and draw your own. The main reason is that my previous m61_kit dev board was broken from playing with it, so I drew this out of boredom. I also hope it can help friends who have an m61-32s module but aren't familiar with board design.

M61 tutorials can be found on the forum; there are many! That's all, goodbye~
