A short while ago, the new Raspberry Pi Zero 2 W was announced. The original Pi Zero and the Zero W are widely used in MMDVM based hotspots and the new Zero 2 W is a direct, drop in replacement. The most obvious question is whether you need to replace your Pi Zero with a […]

How to update and upgrade your Pi-Star based hotspot
There are a couple of methods of updating a Pi-Star based MMDVM hotspot, one upgrades Pi-Star itself and the other method does a full operating system update as well as Pi-Star.
