Image
This post explains how to install MicroPython on an ElectroDragon IoT board using a Raspberry Pi and a USB TTL cable. ElectroDragon Wifi IoT Relay Boards ElectroDragon IoT boards are built on Espressif Systems ESP8266-12 F microcontrollers which include WiFi and 4 MB of flash memory and can readily run MicroPython. ElectroDragon now offer several configurations. The original AC powered dual relay version is used below. http://www.ElectroDragon.com/product/wifi-iot-relay-board-based-esp8266/ Key Specifications Based on ESP-12F ESP8266 Wifi Board This relay board use one AC input, and supports two relay AC outputs. Use mature AC-DC power module, input voltage 85 – 265VAC Relay: HF32F-G-5-HS, Common – open, 10A 250VAC, 30VDC, Control 5V Plastic enclosure design support, package includes the PCB board, plastic case, and self-drilled screws (screws are not assembled).
