Review on π 2-Pack Ximimark Micro USB 18650 Battery Shield Expansion Board with Wemos ESP32 V3 Cable Development Tool LED for Arduino and Raspberry Pi (Includes Cable) by Mike Swanson
Both products are defective. Charging but no output
I tried everything with these two articles. You will charge the battery and that is all it is good for. None of the 3V, 5V or USB jacks are delivering power. I hooked it up to my Agilent oscilloscope and nothing. I'm getting voltage at the battery terminals but it reads about 2V DC in the circuit.
- The output current in this mode can be up to 2A, which can power many control boards.
- Little things
