The LR09A (A110LR09A) is a module built by Anaren Inc based on the sub-1 GHz RF transceiver – CC110L.
For evaluation is really easy to use the AIR Boosterpack

Using one pcb for stand-alone operation:
On the PCB there are some DNP components that are needed only for the stand-alone configuration.
- one simple S1 push switch is used for pairing
- two 47k pull-up resistors – one 0603 as R1 and one at P1.3 (I don’t know why I can’t see the footprint)
- one 0603 LED as D1 and his 0603 limiting resistor R2
- some 0.1uF decoupling caps
The MSP430G2553 needs to be programmed with the Anaren Firmware and configured with ATC – BoosterStack Lite as Sensor (Application State Selector).
