1. Module Overview
At the core of this module is ESP32-S2 *, an Xtensa® 32-bit LX7 CPU that operates at up to 240 MHz. The
chip has a low-power co-processor that can be used instead of the CPU to save power while performing tasks
that do not require much computing power, such as monitoring of peripherals. ESP32-S2 integrates a rich set
of peripherals, ranging from SPI, I²S, UART, I²C, LED PWM, LCD, Camera interface, ADC, DAC, touch sensor,
temperature sensor, as well as up to 43 GPIOs. It also includes a full-speed USB 1.1 On-The-Go (OTG) interface
to enable USB communication.
Note:
* For more information on ESP32-S2, please refer to ESP32-S2 Datasheet.
