Background: HarukiToreda designed a shield for the Heltec V3 for use with Meshtastic that adds lots of IO like pinouts for GPS and environment sensors, a buzzer and more jst plugs for power. I got them on Tindie but they are still available here: https://www.pcbway.com/project/shareproject/Heltec_ESP32_V3_Ultimate_Shield_28cea98a.html.

I couldn't find a case so I remixed a simple box. I built this as a tracker going permanently in my vehicle so I wasn't too concerned with size. It's a little deep but that just means lots of room for activities. I use a chunk of foam to keep the board pressed against the front. A 3ah battery fits snuggly in the bottom. The SMA ports are labeled. This is likely the final revision since this product is low demand.

The latch is a little loose. Just heat it with a lighter for a few seconds then push it in and hold till cool. It'll be snug as a bug after that.
