esp32 s2 wroom single core 32bit module

ESP32-S2-WROOM are two powerful, generic Wi-Fi MCU modules that have a rich set of peripherals. They are an ideal choice for a wide variety of application scenarios relating to Internet of Things (IoT), wearable electronics and smart home. ESP32-S2-WROOM comes with a PCB antenna, They both feature a 4 MB external SPI flash. At the core of this module is ESP32-S2 *, an Xtensa 32-bit LX7 CPU that operates at up to 240 MHz. 

The chip Espressif Systems 3 Submit Documentation Feedback ESP32-S2-WROOM & ESP32-S2-WROOM-I Datasheet v1.2 1 Module Overview 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, TWAITM, LCD, Camera interface, ADC, DAC, touch sensor, temperature sensor, as well as up to 43 GPIOs. It also includes a full-speed USB On-The-Go (OTG) interface to enable USB communication.
