### I2C&#x20;

The board contains an AUX port that supports I2C. The pins in this port you must use for I2C are: Pin 1 = 5V, Pin 2 = I2C\_SDA, Pin 3 = I2C\_SCL, Pin 6 = GND. Also displayed below.

### UART 2 and UART4

The board also contains a UART 1, however, to use UART 1 you need to look at the schematics as it works with Bluetooth. The other two ports for UART are displayed below:
