It’s an STM32 black pill

I did a writeup of the device here:

PN532 with STM32

I’ve recently been messing around with the STM32 - BlackPill microcontroller, and found that the pinout exactly matches that of the PN532 NFC module. Allowing them to be soldered directly toegether into a small form factor rfid scanner (with USB type-C!). I first soldered header pins to the NFC module, then pried off the plastic spacer. Next I put down a strip of Kapton tape to insulate the two boards. Lastly, I placed the STM32 hard up against the NFC module and soldered it into place, befor…
