ESP32-C3 SuperMini Expansion Board for ESP32-C3 MINI Development Board ESP32 SuperMini Development B

The ESP32-C3 SuperMini expansion board is an expansion board specially designed for the ESP32-C3 SuperMini development board. It makes up for many shortcomings of the ESP32-C3 SuperMini development board. You can use the expansion board to connect an external 3.7V lithium battery, which supports charging the lithium battery through USB. The green indicator light lights up during charging. When the green indicator light goes out, the lithium battery is fully charged. The expansion leads to all IO ports, which is convenient for users to save various functions. Various sensors. The expansion board provides users with a better power supply solution. The expansion board has two power supplies, VCC1 and VCC2. The default output voltage of VCC1 and VCC2 is 3.3V. When you need to output a higher voltage, you can short-circuit the PCB. At this time, the output voltage of VCC1 and VCC2 is the power supply voltage 3.7V. The factory default is to use a 0R resistor connected to 3.3V. If you need to output 3.7V, directly remove the 0R resistor and short-circuit the three pads with tin. VCC1 and VCC2 control the voltage output respectively. If you need to use one, just handle which one.<br><br>Color: multi-color Material: PCB<br><br>Package Contents: 1 x Expansion Board<br><br>Only the above package content, other products are not included.
