2.5 Expansion Interfaces
The EVM provides several expansion interfaces that have non-standard/custom pinouts. Each of these
interfaces are introduced and specific pin information is provided.
Note: that some of the interfaces include ‘Direction’ information. This is relative to the EVM, so INPUT is input to
the EVM/output of the connected device. OUTPUT is output of the EVM/input to the connected device.
2.5.1 Heatsink [ACC3_SOM] with Fan Header [J15_CP]
The heatsink supports cooling of the device at ambient temperatures. If your environment or use case requires
additional cooling, a fan can be added to the heatsink. The fan connector is a 3-pin header (440054-3 from TE
Connectivity) and supports 12VDC fans. Mating connector is 440129-3 and 1735801-1.
