GMSK Shield
The node adapter is built around two major components. That is the GMSK modem chip (CMX589) and the controller (ATmega) that takes communication to the host (PC or Raspberry PI) for his account.
The modem supports D-Star hotspot and repeater functionality, half and full duplex so. The transceiver get connected to the present (mini DIN) 9600 bps packet connection.
– Fits on Arduino UNO and MEGA 1280/2560
– Standard mini Din /ps2 9600 packet connector
– half and full duplex mode support
– D-Star
