3.2 Sensor-Radio Interface Connector Details

The mating connector that connects the Radio interface is SFM-105-02-S-D-LC
Samtec.
MOSI, MISO, CS, and SCLK are used for SPI communication between the Radio and the
Sensor, whereas GPIO is used as General Purpose Input/output as well as interruptible
configurable pin.
Note: GPIO_02 pin in the Sensor-Radio interface connector is used as Sensor Data Ready
interrupts (SDR).GPIO_01 is the inverse of Chip Select(SPI_CS).
