Review on 📡 MakerFocus ESP8266 OLED WiFi Development Board - 0.91 Inch ESP8266 OLED Display with CP2102 Chip, Arduino IDE Support, ESP8266 NodeMCU LUA Compatible by Chad Rosier

Played with it for a few days then screen went blank. Otherwise it's a nice little board; just badly designed. Update: The seller contacted me about the broken board claiming it was "compressed in transit". It looks like this could be the case as the board has visible damage which I attribute to poor design. The seller informed me that he will replace the board, after that I will update my review if the new board is not damaged. Update: The replacement has arrived and appears to be working fine. The seller corrected the error very quickly and I am very satisfied with both the product and the seller's helpfulness.
