ESPRESSIF ESP32-S2-WROOM-I-N4

ESP32-S2-WROOM and ESP32-S2-WROOM-I are general-purpose Wi-Fi MCU modules with powerful capabilities and rich peripheral interfaces, suitable for applications such as wearable electronics and smart home devices. ESP32-S2-WROOM features a PCB on-board antenna, while ESP32-S2-WROOM-I connects to an external antenna via a connector. Both modules are equipped with 4MB external SPI flash. The modules are built around the ESP32-S2 chip, which integrates an Xtensa 32-bit LX7 single-core processor operating at up to 240MHz. The CPU can be powered down while a low-power coprocessor monitors peripheral state changes or analog signal threshold crossings. 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, a full-speed USB On-The-Go interface is provided for USB communication.
