I have a rather ancient Raspberry Pi Model B Rev.2 board with the original 26 pin header. This board is not doing anything constructive at the moment so I thought I'd convert it to a Pi-Star node.
Can anyone tell me how to connect the 26 pin header to a 40 pin MMDVM board? I know the pinouts of the Model B, but I don't have any information on the pinouts of the MMDVM board.

Thanks for the help, however it's the pinouts of the MMDVM board I'm looking for - the Model B has these pinouts: https://www.raspberry-pi-geek.com/howto ... 1-and-Rev2

I'd think a starting point would be to look at the R-Pi 40-pin assignments.G6WQH wrote: ↑Sun Oct 16, 2022 5:20 pm Thanks for the help, however it's the pinouts of the MMDVM board I'm looking for - the Model B has these pinouts: https://www.raspberry-pi-geek.com/howto ... 1-and-Rev2
Though what did you search on? Google on "MMDVM pinout" had lot's of hits...

Other than firmware flashing, it appears the only pins really needed are common to 26 and 40 pin R-Pi. At the least, they are the first 10 pins or so.

I would search for the MMDVM_HS_HAT, there are files and schematics on github.G6WQH wrote: ↑Sun Oct 16, 2022 5:20 pm Thanks for the help, however it's the pinouts of the MMDVM board I'm looking for - the Model B has these pinouts: https://www.raspberry-pi-geek.com/howto ... 1-and-Rev2
