The MicroMod ESP32 Processor Board combines Espressif’s ESP32 with our M.2 connector interface to bring a processor board with reliable WiFi and Bluetooth capabilities into our MicroMod ecosystem. With the M.2 MicroMod connector, connecting your ESP32 Processor is a breeze. Simply match up the key on your processor’s beveled edge connector to the key on the M.2 connector and secure it with a screw (included with all Carrier Boards). If you need to swap out your processor for a strong wireless option, make sure to check out the MicroMod ESP32!

The ESP32 includes a laundry list of functionality, including the dual-core Tensilica LX6 microprocessor, 240MHz clock frequency, 520kB internal SRAM, integrated WiFi transceiver, integrated dual-mode Bluetooth, and hardware accelerated encryption (AES, SHA2, ECC, RSA-4096). With this MicroMod processor board, you have access to 8 general use IO pins, dedicated analog, digital, and PWM pins, as well as all the fan favorites – SPI, I²C, UART, and SDIO. Add to that 16MB flash storage and sleep current of around 500µA, and you’ve got a perfect storm of versatility.
