These modules can be shipped with different flash sizes.
At the core of the modules is ESP32-S2 *, 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-S2 integrates a rich set of peripherals including SPI, I2S, UART, I2C, LED PWM, TWAI® controller, ADC,
DAC, touch sensor, temperature sensor, as well as up to 43 GPIOs. It also includes a full-speed USB OTG (OTG)
interface to enable USB communication.
Note:
* For more information on ESP32-S2, please refer to ESP32-S2 Series Datasheet.
