AM261x SOM to HSEC Adapter Board
Description
This evaluation module is a 180-pin High Speed
Edge Card (HSEC) adapter for TI AM261x System-
On-Module (SOM) platforms, allowing for SOM-
based platforms to have backwards compatibility
with Sitara/C2000 HSEC-based EVMs. The
HSEC180ADAPEVM-AM2 connects 180 pins from
the SOM board to HSEC pins for use with legacy
Sitara/C2000 HSEC Docking Stations, such as the
TMDSHSECDOCK-AM263
