I need to have access to pins 19 and 20.

implement the clock signal (SCL) and data line (SDA) of the I2C bus communication protocol. With I2C, several devices can be connected on the same bus and send/read messages to and from the CPU. Internally, the accelerometer and the compass are connected to i2c.

Looking at the board, Image

I can't find the pins. Can someone please point me to the right direction, thanks in advanced.

IIC Interface = D = SDA = 20
IIC Interface = C = SCL = 19
