AI_M61-32S Core Board

Overview

I previously worked with the Anxinco
AI-M61-32S kit development board for a while, but found some minor flaws. So I designed my own, with pins fully compatible with the AI-M61-32S kit. I added a USB port and used an RS2227 to switch between USB and UART serial ports. It also includes an automatic download circuit.
All resistors, capacitors, and LEDs are 0402 diodes. It has one onboard common-cathode RGB LED, and a jumper cap allows selection between USB and serial ports. A custom-coded 50x50 QR code is included.
The BOM is inaccurate; please refer to the schematic .

(Two attached images are included.)

Let's turn on the LED:

launchpad TI board emulator problem
I added a voltage of about 5V some time ago (I was too naughty, I didn't die if I didn't do that... Fortunately, it was a gift from the school...), which caused the LED on the board to go out after a

Please post the photos of the FPGA development boards you have used. Maybe it can give some ideas to those who can't afford to buy a development board and want to DIY a development board. Haha
