5.4 SPECIAL NOTE ON EXPANSION INTERFACES

Expansion interfaces are provided for SPI, UART and I2C. In the very first

production run of the Octopus the silkscreen on the underside of the PCB had

two pins that were mislabeled on the SPI3 interface and two on the Raspberry

Pi UART interface. To be sure that you are connecting your peripheral

correctly, please refer to the PINS.pdf document if using the SPI or UART

interface.
