CuVoodoo #028 – every electron counts



reversing USB meter protocols for long term low DC power logging:
To figure out the energy budget provided by a solar panel for a weather station, I needed a device capable of measuring low DC voltages and currents over a long period of time. For that I used the USB Power Meter (UPM) Web-U2, but I first had to reverse engineered the BLE and USB communication protocols it provided.
