3 Digital Specifications

3.1 CC2650 Hardware

The DEV-RF002 supports several communication interfaces which are provided by the CC2650 device.
Included are one 4 wire SPI interface and one I2C interface. These interfaces are provided as pin connections
on the modules P1 and P2 headers. Ten additional GPIO are available on the CC2650. These IO can be
configured as generic peripheral input / output pins or programmed as communication interfaces including SPI,
I2C and UART.
