Board Overview:

1. USB Interface: Used for downloading programs and power supply. Compatible with a voltage of 4.75V to 5.5V.
2. Charging indicator: A red LED indicates the charging status: 1. Off when the battery is fully charged or not connected; 2. On when the battery is charging; 3. Fast blinking when the device is powered via USB and no battery is connected.
3. User button: This button is controlled via pin IO27/D4.
4. Li-Ion Battery Connector: Supports voltages in the range of 3.5V to 4.2V.
5. Onboard RGB Light: A WS2812 RGB-LED controlled via pin IO5/D8.
6. Onboard LED: An LED controlled via pin IO2/D9.
7. Reset button: This button is used to reset the program.
8. Low-power solder bridge pad: Designed for low power mode and connected by default. Gently cut the thin wire with a knife to disconnect. When disconnected, static power consumption can be reduced by 500 μA. Power consumption can be reduced to 13 μA when the main controller is put to sleep by the program. Note: When the pad is disconnected, the RGB LED light can only be operated via USB power.
9. GDI interface: Special display interface from DFRobot. For more information, see the GDI section of this page.
10. ESP32-E Module: Contains the ESP32-WROOM-32E-N16R2 module.
