Yes, AIM300 is a physical module.

AIM300 is something like C5165N SOM.
AIM300 Series is a highly optimized family of modules designed to 
support AIoT applications, intergrated with qualcomm qcs8550 SOC inside. 
The Module is mounted onto Qualcomm AIoT carrier board to support 
verification, evaluation and development.

In next patch series, AIM300 AIoT carrier board will be a DTS, AIM300 
will be a DTSI, qcs8550 will be a DTSI.
