Review:
Very nice tiny ESP32-C3 board with even battery manahement but with one small drawback making this board less usable on battery operations. WEMOS used 'low cost & worse' power regulator ME6211C33 with relatively big self-consumption (40µA) and voltage drop (-0.1V@100mA ie up to -0.5V@500mA) which forrage battery uselessly. WEMOS should consider minor upgrade and use batter voltage regulator on this board, for example HT7833 (self-consumption one tenth, ie 4µA) or even better TPL720F33 (internal self-consumption only 2.8µA) for better usability on battery operation with longer endurance.
