is this compatible with rp2040 devices like the pico?

Not 100% sure. I think you can use the battery and run the Pico on a breadboard, if that is what you were thinking. The RP runs off of 3.3Volts, so it is close enough. If you want to be safe you can use a TP4056. They are cheap enough.

Can this battery be safely charged with a TP4056?

Hi, yes, it could be charged by TP4056.

Can I charge it with your charging board?

Hi friend, you can use it can be matched with ESP32 Development Board WIFI Kits for Arduino Nodemcu, you could see the picture 4 on the listing.
