Having used several of these hotspots over the years I have found them to be fairly reasonable in both quality and performance. This item, however will be returned. Whilst it transmits received audio via the internet it does not receive input from the radio. It also comes with outdated firmware and needs to be flashed with a more current version. My advice would be to give this one a miss and opt for the more expensive but better quality Openspot or Zumspot offerings.

A simple and cheap way to get (in my case) DMR up and running, as well as being able to use a DMR radio to work YSK and other systems. The HAT can 'translate' between various digital standards so is very useful, eg if you have a DMR radio but the local boxes Fusion. It works fine with my Pi Model 2B.If you are pondering which software to use, I would recommend WPSD as that seems to be more actively updated than Pi-star.Note 1: Be sure to remove the four exposed long pins on the underside of the PCB before installation - these are found between the two underside headers. These connect to the OLED display and need to be croppedNote 2: No documentation is provided, so some web research is required

Didn't work returned for refund

NO documentation is not very clever.I attached the hat to a Pi4B, and used WPSD to flash the "MMDVM_HS_Hat (14.7456MHz GPIO" firmware and selected "MMDVM_HS_Hat (DB9MAT & DF2ET for Pi (GPIO)" as the Radio/Modem type. Also MMDVM Display Type as "OLED Type 3 (0.96" Screen)" Port "/dev/ttyAMA0"Don't know if it is 100% correct but works for me. Hope this helps someone
