Hardware Overview
● RESET button.
Press this button to reset the system.
● LiPo port.
Lithium battery charging interface (lithium battery not included)
● BOOT button.
Hold down the Boot button and press the RESET button to initiate
firmware download mode. Users can download firmware through the
serial port
● 5V Power/Type C interface.
It serves as the power supply for the development board and the
communication interface between the PC and ESP-WROOM-32.
● 4 Crowtail interfaces (1*Analog,1*Digital,1*UART,1*IIC).
Users can program the ESP32-S3 to communicate with peripherals
connected to the Crowtail interface.
