12311-MRB
3.1 12311-MRB Overview
The 12311-MRB is an evaluation board based on the Freescale MC12311 device. The 12311-MRB
provides a platform to evaluate the MC12311 device, develop software and applications. The core device
is accompanied by the 32 MHz reference oscillator crystal, RF circuitry including SMA for antenna
connection and/or instrumentation, and supporting circuitry.
This basic board is intended as the core module for MC12311 evaluation and application development and
can be used in the following modes:
• Simple standalone evaluation platform
• Daughtercard to other Development Platform boards (TWR-RF, 1323x-RCM or 1323x-REM)
• Daughtercard to an application specific motherboard.
