Review on KeeYees Expansion Terminal ESP8266 Development by Dianna Carr

Many ESP8266 projects involve many external components. Here you have a choice of traditional pin headers like on a regular breadboard, or you can use screw terminals to connect bare wires if required. I'm not sure about the usefulness of a "mini PCB" breadboard as it requires soldering components. I suppose you could use this as a final setup, with the idea that the ESP8266 has sockets and can therefore be replaced, but as a prototype board, solder connections are counterproductive. Anyway it looks nice printed and has all the parts needed to assemble as directed. I look forward to using one of these in my next project.
