esp32MX-E ESP32 Board Comes with Ethernet and USB-C Ports (Crowdfunding)

We’ve already covered several ESP32 boards with Ethernet including Olimex ESP32-GATEWAY and Silicognition wESP32, and I’ve just noticed Espressif also made its own with ESP32-Ethernet-Kit.

Modtronix Engineering has another take with esp32MX-E board that beside Ethernet also exposes a USB-C port, a MicroSD card slot, and also adds an STM32F0 microcontroller acting as an I2C I/O expander.

esp32MX-E ESP32 Ethernet & USB-C Boardesp32MX-E specifications:

  • Wireless Module
    • ESP32 dual-core LX6 microprocessor at 160 or 240 MHz, 4 MB Flash, 520 KB SRAM
    • Wi-Fi 4 802.11 b/g/n
    • Bluetooth 4.2 BR/EDR & BLE
  • Storage – MicroSD card slot
  • USB – USB Type-C connector for programming, power, and Virtual COM port
  • Expansion via 14-pin and 20-pin female headers
    • 22x I/O pins of which 4 are inputs only.
    • 4x 5 V tolerant I/O pins
    • Not all I/Os are available when the SD Card is used
    • Programmable pull-up and pull-down resistors on most inputs
  • Secondary MCU – I²C I/O expander implemented with a user-programmable STM32F030F4
  • Misc – User LED, button
  • Power Supply – 5Vvia USB-C port, 4.5 V to 16 V via 2.1 mm barrel connector or Vx pin
  • Dimensions – 64.4 x 42 mm
  • Temperature Range – Standard version: 0°C to 85°C; industrial version: -40°C to 85°C

The company is also working on an esp32MX-EP board that will replace the MicroSD card slot with circuitry to add IEEE 802.3at-compliant Power-over-Ethernet (PoE) support.

You can find esp32MX-E documentation, schematic, PCB files, and later on software on GitHub. Modtronix also provides prototyping daughter boards and an enclosure for their ESP32 board.

ESP32 Ethernet Enclosure

esp32MX-E has just launched on Crowd Supply with a lowly $1,000 funding target. Rewards start at $30 with the board only, getting the industrial version adds $2, and getting a kit with the board, daughterboard and enclosure above requires a $37 pledge. Shipping is free to the US, $7 to $10 to the rest of the world depending on the selected reward, and backers should expect shipment at the very end of January 2020 if everything goes according to plans.

It’s worth noting that Olimex have ESP32-POE and ESP32-POE-ISO , which are Olimex’s Power Over Ethernet boards (non-isolated and isolated versions).

Not sure if worth adding to that table as it would become a little messy.

This is pretty cool. What would be the use case?

Home automation seems the likely suspect.

Ethernet is also used a lot for industrial applications. Seeing that this board is manufactured with industrial temperature components, it is well suited for industrial applications.

Any idea what chip are they using for the ethernet phy?

Hi, sorry for late reply! I did not see these questions earlier. It uses the Microchip LAN8720AI PHY chip.
