ESP32-S3-WROOM-1, ESP32-S3-WROOM-1U and
ESP32-S3-WROOM-2 are general-purpose Wi-Fi + Bluetooth
low-power MCU modules with rich peripheral interfaces and powerful
neural network operations capabilities and signal processing
capabilities, specifically built for the artificial intelligence and AIoT
markets. ESP32-S3-WROOM-1 and ESP32-S3-WROOM-2 use PCB
on-board antennas, and ESP32-S3-WROOM-1U uses a connector to
connect to an external antenna.
5 V to 3.3 V LDO Power converter, input 5 V, output 3.3 V.
All available GPIO pins (except the SPI bus of the flash) have been led
Pin out to the pin headers of the development board. Please see Pin Headers
for more information.
The Micro-USB interface can be used as the power supply interface of
the development board, can burn firmware to the chip, and can also be
used as a communication interface to communicate with the chip
through the onboard USB-to-UART bridge.
Download button. Press and hold the Boot button and press the Reset
Boot key button to enter the "firmware download" mode and download the
firmware through the serial port.
