Re: How susceptible is the DRAWS board to RFI? Metal Case required?
toggle quoted messageShow quoted text
I share this image of a custom case which includes dual fans.. I also wired two AAA batteries to the clock backup.
I used a gpio riser to make room between the PI and the DRAWS for heat syncs and a center fan. Simply bought two PI stack style cases and modified one for the DRAWS connects.
I've been running it for a couple days now as APRS tracker with no temp issues.

Acrylic cases are suitable with a couple of caveats:
Be mindful of Temperature rise, probably not suitable for Pi4
One customer had RFI issues and fixed them with a grounded metal plate on top of their acrylic case
C4Labs makes acrylic cases for DRAWS both versions 1 with the SMA on the side and version 2 with the SMA on the end. They are working on a new version for the current rev, which has the Barrel Connector for DC.

Just askin'. Is an acrylic case suitable, or should the Pi and DRAWS be housed in a metal case to help prevent RFI?
