Board Overview:

1. USB Interface: Used for programming and power supply, compatible with a voltage of 4.75V to 5.5V.
2. Charging Indicator: A red LED shows 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 Pad: This pad is designed for low-power mode and is connected by default. You can cut the thin line with a knife to disconnect it. When disconnected, the static power consumption can be reduced by 500 μA. Power consumption can be reduced to 13 μA when the main controller is put into sleep mode by the program. Note: When the pad is disconnected, the RGB LED light can only be operated via USB power.
9. GDI Interface: This is a special display interface from DFRobot. For more information, see the GDI section of this page.
10. ESP32-UE Module: Contains the ESP32-WROOM-32UE-N16R2 module.
