AM273x Evaluation Module
The AM273x EVM is an Evaluation module designed to develop software and evaluate the AM273x Radar
Controller and Processor SoC from Texas Instruments. The AM273x is a multicore SoC designed to provide an
integrated control and processing platform for TI AWR mmWave radar front-end devices in both single-device
and cascaded modes of operation. The signal interface between the AM273x EVM and the AWR2243BOOST
mmWave Radar EVM uses the 60-pin Samtec high density connector.
