I have an AI-Thinker ESP8266MOD on Lolin v3 board and a 9-axis sensor, MPU9250. I have seen many examples of using the MPU9250 with Arduino boards, but none with ESP8266.

How should I access the MPU address with this board?

Can the Digital pins (D0-D8) can be used for serial data as in this example?

Sorry if my question sounds stupid, I'm pretty new to this. :(

Since the question is about using an ESP8266 you may get more answers from the Electronics Exchange forum where they look at these MPUs. – Matt Sep 19 at 8:12

You'll need I2C to communicate with the MPU9250.

The ESP8266MOD device does have I2C capability, but I'm not sure what pins the break out to in that Lolin v3 board (possibly GPIO2 = D4 = Data, and GPIO14 = D5 = Clk).

So yes, you can connect it similar to the image in your link, bit the D0-D8 pins may be different.

Thank you. Let me try and get back. – Sen Jacob Sep 20 at 8:05
