Review on 🔥 MMDVM Duplex USB Hotspot Module Kit with Dual Antenna Board for DMR/P-25/D-Star by Andrea Bone

Ok this MMDVM board works great. The only issues I've found are fairly minor: 1. The modem firmware outside of the package is very out of date, mine came from 1.3.7 and the current version is 1.5.2 so you'll need to use the update command in Pi Run Star via SSH and that brings me to problem 2. The modem upgrade won't come out of the package because you need to short/solder the JP1 jumper which is on the bottom right above the little red and yellow dots that I added in the photo. It's specific to this design and doesn't make sense to me, but I did some soldering and the upgrade went fine. Hope this helps future buyers.
