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 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 …
