In additional to functioning standalone, the TWR-RF-SNAP is designed to be used in the Freescale

Tower System. When inserted into the Tower System a Tower MCU module can utilize the TWR-RF-

SNAP to relay information to additional SNAP nodes, including the provided SN132 USB Dongle. The

TWR-RF-SNAP can also access compatible peripheral modules directly using I2C and SPI.

To ensure proper functionality of the TWR-RF-SNAP within the Tower System the Primary Edge

connector (marked with the white stripe) must be inserted into the Primary Elevator.

The TWR-RF-SNAP is also compatible with the General Purpose Tower Plug-in modules (or TWRPIs). A

TWRPI module can be inserted directly into the available socket on the TWR-RF-SNAP. The TWRPI

socket on the TWR-RF-SNAP provides access to I2C, Analog, and GPIO's.
