The esp32MX-E is a versatile ESP32 based board with Ethernet, USB Type C, WiFi, Bluetooth and more. It is designed with ease-of-integration in mind, so you can use it to simplify and accelerate the development of your own custom boards.

Advanced Power Supply

The esp32MX-E has an advanced power supply circuit that accommodates multiple inputs, provides 3.3 V and 5 V outputs, and delivers over 2 A of current to the user. It has high current switch mode regulators, at both 3.3 V and 5 V, to ensure low power consumption and high efficiency. Power can be supplied via the USB C connector, a 2.1 mm barrel connector, or the external power supply pin. This allows board designers to integrate the esp32MX-E as a daughterboard and get 3.3 V, 5 V, and supply voltage via the pin header connector.

Integration into Custom Hardware

Designed both for standalone use and for integration into larger projects, esp32MX-E has two female headers, so you can plug a small expansion board into it or use esp32MX-E itself as a daughterboard. All connectors, switches and LEDs are on one side of the board, which makes it far easier to design custom enclosures. We supply raised male headers, for when esp32MX-E is in use a daughterboard, that provide 14.5 mm of space between it and the baseboard. A single board spacer and a screw are all you need for a secure fit, and we provide both a threaded and a non-threaded 14.5 mm spacer. Two additional screw holes are available, but are not required when using esp32MX-E as a daughterboard.


Capacitors, in particular, are often the cause of failure in electronic devices. We have sourced the capacitors in esp32MX-E from extremely reputable manufacturers like Panasonic, Samsung, Murata, TDK, and Yageo. Furthermore, all of our capacitor voltages are overrated by at least 190%.

Customizable Enclosure

We provide the Eagle Schematics and PCB files for a prototype daughterboard and enclosure faceplate. You can use these design files to quickly develop your own custom product.

User I/O

esp32MX-E has a secondary 32-bit ARM processor (STM32F030F4) that serves by default as an I²C port expander. If required, you can program this secondary microcontroller with custom firmware.

Current & Future Models

We also offer an industrial version of this board that will operate within a temperature range from -40°C to +85°C. And, though it will not be part of this campaign, we are currently in the process of designing esp32MX-EP. It will be the same size and have the same connectors as the esp32MX-E, but will swap out the SD card reader in favor of IEEE 802.3at-compliant Power-over-Ethernet (PoE) support.
