- Connection:
- connect SDA/SCL of BH1750 sensor to GPIO5/GPIO6
**Note:** There is only one i2c device on esp32c3, so you can't try any master-slave example for esp32/s2 in this repo. But you can try external devices. If you find anything wrong with your device, please try connecting pull-up resistors by yourself.
**Note:** There is only one i2c device on ESP32-C3/ESP32-C2/ESP32-H2, so it is not possible to perform any ESP32/ESP32-S2 self-test example from this repo. However it is possible to test I2C with external devices. If you find anything wrong with your device, please try connecting external pull-up resistors.

### Hardware Required
To run this example, you should have one ESP32, ESP32-S or ESP32-C based development board as well as a MPU9250. MPU9250 is a inertial measurement unit, which contains a accelerometer, gyroscope as well as a magnetometer, for more information about it, you can read the [datasheet of the MPU9250 sensor](https://invensense.tdk.com/wp-content/uploads/2015/02/PS-MPU-9250A-01-v1.1.pdf).
