Wemos® D1 Esp-Wroom-02 Motherboard ESP8266 Mini-WiFi NodeMCU
Posted: Sat Mar 03, 2018 11:31 amI need to add an I2C device to this module. Unfortunately, the I2C pins are only connected to the oled display controller. Any suggestions on ways to run a second I2C buss? Or a little direct solder of wire wrap wire to the pins of the Esp8266?
