Specific cases

Follow: pi-star or 192.168.50.1

Downloaded the Pi-Star Pi OS image and followed the instructions to setup and configure.

Pi-Star OS (Raspbian integration MMDVMHost, Serial of DMR/YSF/P25/D-STAR/NXDN/POCSAG gateway serivces , Pi-Star Dashboard)

When you finally do connect to a DMR group you have to press the radio's PTT momentarily to make the hotspot register the connection and allow you to hear the DMR group conversations.

Note: The OLED display on this board is "OLED Type 3" in the Pi-Star configuration menu.
Easy install

Was a breeze to assemble. Was easy to get running and use for DMR.

The build quality is solid and the screen is easy to read. The OLED screen provides enough information for everyday use.

It also has decent range given its size and low power.
Assemble your own MMDVM hotspot

Users who purchase this product should have a working knowledge of digital modes, a digital radio, a working Raspberry Pi, and a flashed microSD card with Pi-Star or WPSD installed. Nothing else is needed except a power supply for your Pi.

Test whether the MMDVM hotspot board is working: mmdvm.club/index.php/archives/263/

Update WPSD system: mmdvm.club/index.php/wpsd.html
Compatible with P4 settings

Since our mmdvm board is defautly setup for Pi-Zero W, Pi 3. If you do want to connect it with your Pi 4, you could try below methods. PICK ONE.

Method 1: Remove the R1 resistance of the hotspot board (single/dual) ;

Method 2: Cut off the 2 Raspberry Pi pin headers on the corners of the board ( pick one to operate on your MMDVM board, refer to the product image for the R1 and 2 pin headers locations)

Where can I find some documentation on the board that describes what the intended meaning of the LEDs?

In the configuration - log, can see and download log, to discovery problem.

If the Raspberry fails to connect the hotspot board, please try update the firmware of the hotspot board.

The correct command is” sudo pistar-mmdvmhshatflash hs_hat”. More info pls view: //amateurradionotes.com/pi-star-notes.htm#hotspotfwupdate

To get this to work on a Pi4, did have to remove resistor "R1" or cut the pins on the Pi like the listing mentions?

When the product is powered on the SVC light does not flicker, it may be necessary to remove R1 in such cases

Tried Pi Zero 2W boards with MMDVM and supplied GPIO adaptor plugs do not make a snug and tight connection, not working

Worked On First Boot

Reviewed in the United States on February 29, 2024

Verified Purchase

This board is what it says it is. Quality construction, packaged well, and worked on first boot after installing to the top of my Raspberry Pi B+. The OLD screen is small but provides enough information for everyday use. I'm using it on UHF and have not tested it on VHF. I mostly use it as a Fusion Hot Spot C4FM, which has been flawless.

Users who purchase this product should have a working knowledge of digital modes, a digital radio, a working Raspberry Pi, and a flashed microSD card with Pi-Star or WPSD installed. Nothing else is needed except a power supply for your Pi.

Follow the instructions to install on a raspberry pi. Works great and I can get into it about 1 mile away. ( many obstructions , houses, etc) I can enjoy my dmr radio around my neighborhood as I walk the dog. Programming is a bit confusing but those were from another source.

works great vhf/uhf but really no instructions

Reviewed in the United States on January 7, 2023

Verified Purchase

If you have made a hotspot before, and know the steps, this will work great for you. If your new, the lack of directions will, may be intimidating and even frustrating. Now with that said, its a quality made board , no bad solder joints, worked in vhf, uhf for me. (I did put a different antenna on for vhf) it comes with a small display installed on it, you can add a nextion display as I did, a little high in price but the fact that it works great (if you don't need instructions) means it was worth the price to me.
Note: if you use this with a usb hat instead of a raspberry pi, you need to know that bluedv will not activate the display as the bluedv software puts a "display" on your pc screen.
I did run it in dstar and fusion, but im sure all the advertised modes work.
enjoy ! Doug

Works well with Yaesu FT-70D but this is not a system for the feint of heart

Reviewed in the United States on October 19, 2020

Verified Purchase

I am an amateur extra class ham of 35 years and an electrical engineer and wanted to connect to the YSF and DMR networks using a Yaesu HT. The board worked as advertised but you may have a steep learning curve into the world of digital hotspots (I did). Be ready to spend time on the Internet reading and watching YouTube videos to get connected once you have assembled your hotspot.

Mated this MMDVM Hotspot Board with an older Raspberry Pi 3B (1 GB) that I had laying around. Downloaded the PiStar Pi OS image and followed the instructions to setup and configure. No problems getting it to operate, and it worked with my Yaesu FT-70D on UHF in YSF mode. Activated YSF2DMR mode then I could connect to DMR groups using my Yaesu HT. Bought a Raspberry Pi Zumspot plastic case ZRPi-1AS from C4Labs and it fit perfectly.

Note: getting connected to digital networks using this hotspot was not "plug and play" easy for me; even though it worked I spent many hours fiddling with setting and searching the Internet for help getting my YSF-capable radio to talk on the DMR network. Little things like: when you finally do connect to a DMR group you have to press the radio's PTT momentarily to make the hotspot register the connection and allow you to hear the DMR group conversations. This fact was not documented anywhere that I could find. But now that I got through all that it is a joy to use.

Another note: The OLED display on this board is "OLED Type 3" in the PiStar configuration menu.

And now I'm on DMR with a Hotspot

Reviewed in the United States on January 21, 2024

Verified Purchase

Now I'm on DMR with a Hotspot. I had a Pi 3B+ laying around and wanted to get on DMR with my Ailunce HD1. Installation and configuration of the hat with Pi Star took about an hour. Everything came on line and I was talking with others around the US. I'm super pleased. I still need to adjust the offsets, but I'm happy with the progress so far. I recommend this hat for your mobile hot spot.

Update: I’ve been using this MMDVM hat for almost three weeks. That is not a long time but it continues to be a positive review. I switched from Pi-Star to WPSD and I couldn’t be happier. WPSD was able to flash the firmware to the most recent version!

I’ve moved the MMDVM hat to a Pi zero 2 w and a c4 labs case. It rocks!

I entered the world of D-Star almost immediately with one of these. Dementia abounds! You can almost hear the proteins folding. I spoke to a hoarder, as well! What delights in the amateur radio service!

Strap one of these to a Raspberry Pi and next time you see Ebon Upton, thank him for how his revolution aided digital radio!
