ESP32-S3-WROOM-1 is a powerful, generic Wi-Fi+ Bluetooth LE MCU module built around the ESP32-S3 series of SoCs. On top of a rich set of peripherals, the acceleration for neural network computing and signal processing workloads provided by the SoC makes the module an ideal choice for a wide variety of application scenarios related to Artificial Intelligence of Things (AIoT), such as wake word detection, speech commands recognition, face detection, and recognition, smart home, smart appliances, smart control panel, smart speaker, etc.

ESP32-S3 integrates multiple peripherals including SPI, LCD, Camera interface, UART, I2C, I2S, IR remote control, pulse counter, LED PWM, USB Serial/JTAG controller, MCPWM, SDIO host, GDMA, TWAI® controller (compatible with ISO 11898-1), ADC, touch sensor, temperature sensor, timers, and watchdogs, as well as up to 36 GPIOs. And it also includes a full-speed USB 1.1 On-The-Go (OTG) interface to enable USB communication.

P: power supply; I: input; O: output; T: can be set to high impedance. Pin functions in bold font are the default ones. The default functions of pins 28 ~ 30 are determined by the eFuse bit.
In modules that have embedded OSPI PSRAM (i.e., that embed ESP32-S3R8), pins IO35, IO36, and IO37 are used to connect to the OSPI PSRAM and not available for other uses.
