Super mini stlink&daplink, Hezhou air32f103, verified

Overview

Using air32f103cbt6 as the main control, we have optimized three generations and continuously reduced the PCB. Finally, it supports the debugging of C to C lines and is compatible with the firmware of stlink and DAPlink. Only the pins of the indicator light are different. I used three solder joints for the indicator light. board, with GND in the middle and two LED lights welded on both sides, it can be compatible with both stlink and DAPlink firmware.

I want to make an automatic tracking smart car with black lead wire. Should I use a three-way infrared pair tube or RPR220?
I want to make an automatic tracking smart car with black lead wires. Is it better to use a three-way infrared tube or a photoelectric sensor chip RPR220? I initially plan to use C51 to write it. Whic
