CMT2300AW RF-EB User Guideline

Summary

The CMT2300AW evaluation platform is designed to help users evaluate the performance of
CMOSTEK's wireless transceiver chip CMT2300AW. The evaluation platform consists of a pair of universal
wireless evaluation boards (RF-EB) and a pair of wireless modules（CMT2300AW-EM）. Users can evaluate
the main characteristics of the CMT2300AW chip through the platform, such as the actual environment
communication distance, signal strength and packet loss rate.
