ESP32MiniKit Wemos

The ESP32 MiniKit is a small WiFi and Bluetooth board in the format of the WeMos D1 Mini. In addition to WiFi it offers Bluetooth and Bluetooth LE as well as more IO pins and improved analog inputs than the ESP8266. A CP2104 USB-to-serial converter connects the board to the computer via USB-C. It can be programmed with Arduino.

Important: Thanks to its small size the board fits on a breadboard, with room for jumper wires on both sides. This only works if only the inner pin headers are soldered on. With all pin headers it no longer fits on a breadboard.

Recommended Accessories:

• 0.5m USB 2.0 Type-C Cable black 66W
• Breadboard / Hole Grid Plug-In Board Half-Size
• WeMos D1 Mini Micro SD Shield

Features:

• Arduino IDE: enter the URL https://espressif.github.io/arduino-esp32/package_esp32_index.json under Preferences, install «esp32» in the Boards Manager, select board «MH ET Live ESP32MiniKit»
• USB-C for programming and power supply, RST button
• According to the RIOT documentation, shields for the D1 Mini also work here, tested with Micro SD and BMP180 shields
