MMDVM Simplex and Raspberry Pi 3 enclosure
cults3d
This is an enclosure for the typical chinese MMDVM Simplex hat mounted on a Raspberry Pi 3. The MMDVM Hat I used was purchased from Amazon (https://www.amazon.com/gp/product/B07VW819NW/). The enclosure is a modification of a most excellent design by MP (https://www.thingiverse.com/thing:608169). The enclosure is 3 parts: bottom, top and a small spacer that mounts under the antenna so when the antenna connector is tightened, it secures the hat to the top of the enclosure. I created a lot of holes for air flow so a fan should not be necessary (use a heatsink on the processor). Pi-Star software reports a temperature of 50c in a room with ambient temperature of 22c. 19 January 2021 Added a new STL I called "Chair" to elevate the enclosure 15mm so air could flow under the assembly.
