Soynerdito has been working on a small hardware adapter for ESP8266-WIFI Uart module:
Idea is to provide a small board to allow connecting the ESP8266 ver ESP02 to a breadboard. It is kept small so the price is cheap. A small batch was ordered to oshpark and waiting for order to arrive to see if the idea works.
- Allow input of 5V
- Exposes 3.3V regulated
- Level shifter for RX and TX signals (can be connected directly to Arduino)
- Breadboard friendly pinout
- Minu usb connector on the bottom (for 5v power input only)
Project files available on Github.
