ESPRESSIF ESP32-S2-WROVER-I-N4R2

ESP32-S2-WROVER and ESP32-S2-WROVER-I are general-purpose Wi-Fi MCU modules with powerful performance and rich peripheral interfaces, suitable for applications such as wearable electronics and smart home devices. The ESP32-S2-WROVER features an on-board PCB antenna, while the ESP32-S2-WROVER-I uses a connector for an external antenna. Both modules are equipped with 4MB external SPI flash and 2MB SPI PSRAM. Both modules are based on the ESP32-S2 chip. The ESP32-S2 chip integrates an Xtensa 32-bit LX7 single-core processor operating at up to 240MHz. You can power down the CPU and use the low-power coprocessor to monitor peripheral state changes or detect when certain analog values exceed a threshold. The ESP32-S2 integrates a rich set of peripherals, including SPI, I2S, UART, I2C, LED PWM, TWA controller, ADC, DAC, touch sensor, temperature sensor, and up to 43 GPIOs. In addition, the ESP32-S2 features a full-speed USB On-The-Go interface for USB communication.
