Introduction
The RAEMesh Radio module offers a complete microcontroller/transceiver solution Containing all hardware features
necessary for development of a low data-rate, low-power wireless application. The primary components include an IEEE
802.15.4 compliant Zigbee-ready transceiver , a microcontroller, a 40-pin interface connector, a MMCS antenna
connector,
This documentation describes the RAEMesh radio module hardware interface as well as RAE System’s Command
Interface.
