Description:

ESP32-C3 Supermini expansion board is a special ESP32-C3 supermini development board designed for an expansion board, which makes up for the many shortcomings of the ESP32C3Supermini development board, the use of expansion boards can be connected to an external 3.7V lithium battery, support for charging the lithium battery via USB, charging the green indicator light, when the Green indicator light when charging, when the green indicator light is off, the lithium battery is fully charged, expanding the lead out of all the IO ports to facilitate the user section of a variety of sensors.
ESP32-C3 Supermini expansion board to provide users with a better power supply solution, the expansion board has a total of VCC1, VCC2 two power supply. Default VCC1, VCC2 output voltage is 3.3V, when you need to output a higher voltage, you can short the PCB (as shown in the following figure of the position), at this time, VCC1, VCC2 output voltage is the power supply voltage of 3.7V. Default is the use of the factory is connected to the 0R resistor to the 3.3V, if you need to output 3.7V, directly remove the 0R resistor, the three pads with a tin short. VCC1 and VCC2 control the voltage output respectively, you need to use to take one, just deal with which one.

Expansion board parameters:
Voltage: 3.7V
External interface: PH2.0
Size: 37.4mm * 22.53mm
