Raspberry Pi has two I2C interfaces. The I2C_1 of the RPi is connected via the main P1 connector and does not need any special modification.
All the onboard ICs are connected to this bus. The second I2C bus, I2C_0, is wired out via the P5 connector which needs to be soldered from the bottom of the Raspberry Pi. Please check our online tutorial for further information.
The I2C_1 is by default wired out via the onboard RJ11 connect or labeled I2C and features ESD protection.
UniPi also features optional I2C port (labeled I2C_1) on the edge of the board but does not have any connector by default.
Please note that the I2C_0 has been reserved for special purpose starting with RPi models + and thus is no longer recommended to use.
