About LEDs and switches
| Item | Description |
|---|---|
| LED RX | FT232RQ controlled LED / Flashes on UART TX data transmission. |
| LED TX | FT232RQ controlled LED / Flashes on UART RX data transmission. |
| Reset switch | Resets the ESP32 and other devices. |
| Boot mode switch | Switch to change to boot mode.Press and hold the boot mode switch while writing a sketch. |
| micro USB | It is used for writing a sketch to the MCU and serial monitoring by connecting a PC.This also converts USB’s VBUS(5V) to 3.3V by using step-down power circuit and provide VBUS and 3.3V to each leaf. |
| Antenna | This is a shared antenna for Bluetooth LE and Wi-Fi. |
