NodeMcu Lua WIFI разработочная плата для интернета вещей на основе ESP8266 CP2102 беспроводного модуля
US$6.99 US$13.99

Q: Do these support I2C? I notice that other NodeMCU boards don't - Thanks for showing that with the other boards BTW.

DukeResonant Yes they work on i2c. D1 and D2. Be sure to always use pull up resistors. 2.2k is okay with 3v3 but 4.7k works
