KEHIPI 2PCS ESP32-C3 MINI Development Board Extended/Expansion Board, Esp32 C3 Esp32-c3 Super Mini 4MB Wi-Fi B-luetooth Development Board(Only Expansion Board)

Expansion Board Overview:

The ESP32-C3 SUPERMINI expansion board is specifically designed for the ESP32-C3 SUPERMINI development board. It addresses many

limitations of the ESP32C3 SUPERMINI development board.

* The expansion board allows for the connection of an external 3.7V lithium battery and supports charging the battery via USB.

* The green indicator light turns on during charging and turns off when the battery is fully charged.

* All 10 GPIO pins are extended, making it convenient for users to connect various sensors.

* The expansion board provides a better power supply solution, featuring two power outputs: VCC1 and VCC2.

* By default, VCC1 and VCC2 output 3.3V.

* If a higher voltage output is required, you can short the PCB (as shown in the image below). In this case, VCC1 and VCC2

will output the power supply voltage of 3.7V.

* The default factory setting uses a 0 resistor connected to 3.3V. To output 3.7V, remove the 0 resistor and bridge the

three solder pads with solder.

* VCC1 and VCC2 control the voltage output independently. You only need to modify the one you intend to use.

Expansion Board Specifications:

* Voltage: 3.7V

* External Interface: PH2.0

* Dimensions: 22.50 mm × 37.40 mm
