$12 AI Light ESP8266 based WiFi RGB Light Bulb Supports MQTT via ESPurna Open Source Firmware

AI-Thinker is famous in the maker world for their ESP8266 modules, but they’ve also recently launched a WiFi RGB light bulb that sells for about $12.5 and up on Ebay and Aliexpress (here and there).

Several companies are working on such ESP32 boards however, and they tend to show the development progress on social networks, so I thought it would be fun to look at what’s coming… Amica (NodeMCU) ESP32 Board The current NodeMCU board is one of the most popular ESP8266 development platform, and that’s not surprising they are working on an ESP32 version. I don’t have pictures nor full  specs of the board yet, but the company showcased their early work on ESP32 last June. Widora-air I only discovered Widora recently via their NEO WiFi board running OpenWrt, but they are …
