4.1 1323x-RCM Overview
The Remote Control Motherboard (1323x-RCM) is a motherboard that accepts the 1323x-Modular
Reference Board (1323x-MRB) plug-in module (daughter card) and supplies a power supply and a rich set
of interface peripherals. The two boards in combination provide a complete platform to evaluate the
MC1323x, write software, and develop a full featured IEEE 802.15.4 based wireless remote control.
