esp32MX-E is a high quality ESP32 board with Ethernet support, a USB Type C connector, an SD card reader, and multiple switch mode power supplies. It features advanced power circuitry and support for multiple inputs, including USB, barrel, and a Vx external power supply pin.
Designed both for standalone use and for integration into larger projects, it has two female headers, so you can plug a small expansion board into it or use the esp32MX-E itself as a daughter board. esp32MX-E has a secondary 32-bit ARM processor (STM32F030F4) that serves as an I²C port expander. You can program this secondary microcontroller with custom firmware if required.
We offer a version of esp32MX-E with an enclosure. (If you want to design your own enclosure, you will find that all connectors, switches and LEDs are on one side of the board, which makes doing so far easier.) We will also offer an industrial version of this board that will operate at temperatures as low as -40° C.
Though it will not be part of this campaign, we are also in the process of designing the esp32MX-EP. It will be the same size and have the same connectors as the esp32MX-E, but will give up the SD card reader in favor of IEEE 802.3at-compliant Power-over-Ethernet (PoE) support.
