ESP32-S2-WROVER and ESP32-S2-WROVER-I 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 related to Internet of Things (IoT), such as embedded systems, smart home, wearable electronics, etc.
ESP32-S2-WROVER comes with a PCB antenna (ANT). ESP32-S2-WROVER-I comes with a connector for an external antenna (CONN).They both feature a 4 MB external SPI flash and an additional 2 MB SPI Pseudo static RAM (PSRAM). The information in this datasheet is applicable to both modules.
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.
