1 Hardware Platform Introduction
The CMT2310A evaluation board hardware test platform is composed of CMT2310A-EB and CMT2310A-EM：
 CMT2310A-EB is the test panel of the evaluation board, using HC32L136 as the development board
of the CMT2310A module, factory set with CMT2310A function and performance evaluation firmware,
and can also be used as the CMT2310A development board.
 CMT2310A-EM is the evaluation module, and the module is affixed according to the matching
parameters of the target frequency band (2 common frequency bands are provided: 434MHz and
868MHz with transmission power of +20dBm Direct Tie hardware matching mode), which can be
used by users for evaluation before scheme selection or reference comparison in design.
CMT2310A-EM also supports to connect to the RFPDK upper computer interface software through
USB Programmer and realizes online control of the CMT2310A functional testing and verification.
