Zodiac FX - SPI Header

The SPI connector allows the Zodiac FX to connect to other devices using the industry standard Serial Peripheral Interface (SPI). A Master jumper has also been included on the board to allow physical selection of Master or Slave.

Information on the SPI standard can be found on Wikipedia 


NOTE: IRQ 1 is connected to a GPIO pin on the MCU to allow for a SLAVE device to request access to the SPI bus.
