At the core of the modules is an ESP32-S3 series of SoC *, an Xtensa
®
32-bit LX7 CPU that operates at up to
240 MHz. You can power off the CPU and make use of the low-power co-processor to constantly monitor the
peripherals for changes or crossing of thresholds.
ESP32-S3 integrates a rich set of peripherals including SPI, LCD, Camera interface, UART, I2C, I2S, 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
45 GPIOs. It also includes a full-speed USB 1.1 On-The-Go (OTG) interface to enable USB
communication.
