I needed a way to program a Tuya CB3S chip without removing it from the PCB, and didn't want to solder if I didn't have to. So I made a jig that uses 1mm pogo pins.

Print this in whatever filament you want (I used simple PLA) then hand-drill the holes for whichever pins are needed for programming using a 1mm bit. Press-fit the pogo pins so they stick out a few mm, solder or clip wires to the pins, and use a clamp for hands-free if you want.

This should work with ESP-12E, ESP-12F, and Tuya CB3S boards. I haven't tried others but they might also work
