OUT OF STOCK as of 6/7
More expected 7/7
Next LOT delayed until 7/24
Thanks to many of you the last lot sold out much much faster than anticipated. I began the process of building the next lot when I was 1/2 sold out existing lot. But they went so fast I was caught flat footed. I don't expect to have the next lot here until ~ 24 July. I will update that date here as I know more.
This is a Duplex Multiple Mode Digital Voice Modem in a Raspberry Pi Zero HAT form factor. While there are other versions of this type of Duplex board on the market this is the ONLY one which keeps the Pi Zero form factor that has become so popular. This will enable you to keep the portability of the MMDVM_HS_HAT while at the same time allows you to enjoy the benefits of a DUPLEX board. For DMR this means it can have QSO's happening on both time slots.
Note: The photos show the board with u.fl connectors installed. These are a user installed option. The pads are there but it is up to the customer to install these connectors.
Questions? : Please follow the link in the DOCUMENTATION section.
Note: This board was designed to be mated to a raspberry PI Zero. It will work with ALL raspberry PI boards, however there is a mechanical interference between the right hand SMA connector and the USB connectors on the PI. There is an easy work around. Put what is called a stacking header on the PI board first. You can find one on Amazon HERE.
All the features of a duplex board without having to sacrifice the convenience of the Pi Zero form factor
