Boards perfect in every way. But beware if your IO does not seem to be doing what you think it should. Something I found out the hard way is that you should be targeting the "LOLIN(Wemos) D1 R2 & mini" and not the "Wemos mini R1". Both will work and depending on you code you might not run in to the issue I did. When targeting a "Wemos mini R1" you will find that if you use the pin mask designation constants like "D0,D4,D5" and so on.. You will find that they do not match the board you are working on. Well some will be correct like D5,D6 and D7 but the rest will be incorrect. So either use the GPIO #s or be sure to target the "LOLIN(Wemos) D1 R2 & mini" in the Arduino IDE.
