WeMos D1 UNO R1 ESP8266 Arduino UNO-R3 Clone

The above MPJA data sheet claims “Arduino UNO-R3 clone board” .. where Arduino UNO-R3 added SDA & SCL pins, 5v IOref pin (next to reset) maybe 3.3V tolerant shields..? https://startingelectronics.org/articles/arduino/uno-r3-r2-differences/ https://www.quora.com/What-is-the-difference-between-an-Arduino-Uno-and-an-Arduino-Uno-R3

It has a D1 UNO R1, not R2: MPJA Data sheet has current Wemos URL: https://wiki.wemos.cc/tutorials:get_started:get_started_in_arduino

Includes CH340G USB-serial adapter

• not programmable
• cannot use Windows HID game controller control panel

I/O is 3.3V; NOT 5V tolerant; most UNO shields would be 5V… https://www.reddit.com/r/arduino/comments/3znkpv/arduino_uno_esp8266_single_board_wemos_d1_any/

Non-UNO ESP8266 tech info from https://www.amazon.com/dp/B01D1D0EO4 https://nurdspace.nl/ESP8266

Good R2 documentation, including AT commands https://www.addicore.com/D1-DevBoard-p/ad286.htm
