ESP8288 IOT Board & I2C Ports
I have just purchased an ESP8266 IOT Board Version 1.0 and I would like to connect a crowtail BME280 Sensor to it. This is an I2C device, but I am having trouble woring out which ports are the default I2C Ports on the ESP8266. Could somebody please help and let me know.
Thanks for any help in advance.

Hello @davidwoolterton ,
Please check the schematic of the IoT board: https://www.elecrow.com/wiki/image/5/5b/ESP826_IOT_Board_v1.0.zip
and the datasheet of the ESP8266-12E module: https://docs.ai-thinker.com/_media/esp8266/docs/esp12e_datasheet.pdf
The IIC pin are D4(SDA) and D14(SCL).


Thank you, as I was struggling to find that document. When I get a micro usb cable I will give it ago.
