Just like my original ESP-01 Tamer (see my other projects), but with a micro USB socket instead of the USB-A plug.

This little board makes it super easy to use the ESP-8266 ESP-01 board in the Arduino environment. The following features are provided:

• CH340G based USB serial interface
• Auto control of RST/IO0 for downloading (uses DTR and RTS like NodeMCU, Wemos mini, etc.)
• Onboard 3.3v regulator
• Bidirectional 5v/3.3v logic level conversion on Rx, Tx, IO0, IO2
• Breadboard-friendly breakout of all essential pins
