ESP32-S2 WROOM Module - 4MB (PCB Antenna)

The ESP32-S2 WROOM Module is a remarkable advancement in the ESP32 WROOM module series, boasting enhanced security, display support, and superior environmental performance. The module comes equipped with transparent external flash and RAM encryption, secure boot features that permit only signed firmware, and HMAC and Digital Signature modules that use software inaccessible keys to generate SHA-MAC and MAC signatures, effectively addressing most of the security flaws of the previous generation.

The ESP32-S2 WROOM Module is powered by the ESP32-S2 Xtensa® single-core 32-bit LX7 microprocessor, with a processing speed of up to 240 MHz. The module is rich in peripheral features, including 43 GPIOs, 1 full-speed USB OTG interface, SPI, I2S, UART, I2C, LED PWM, LCD interface, camera interface, ADC, DAC, touch sensor, and a temperature sensor. The module also offers the flexibility of USB OTG functionality or an LCD interface.

With an integrated antenna and software stacks, the module is fully certified and comes with 4MB of flash. The module can function in a wide range of temperatures, from -40 to 125 degrees Celsius, making it suitable for various environments.
