Duranode AllStar UHF RF FM Hat Kit

DuraNode Simplex 70cm FM Allstar Node RF hat kit for AllStar. This RF hat kit is to enable you to build a Raspberry Pi hosted AllStar RF Node using the AllStarlink network.

This hat uses a NiceRF SA818S-CE UHF 420 – 450 MHz radio module. Uses the Cmedia CM108B USB audio IC. The hat is fully assembled, no soldering needed on the hat. This RF hat has a 40 pin Raspberry Pi header so it fits the Raspberry Pi 3B/3B+ or 4B series. Three LED’s indicate the connection status – Blinking white = Comms, Amber – RX  and Blue – PTT. The DuraNode Hat RF output power is around 400 milliwatts.

Assembly Skill Level: Intermediate – only 2 solder joints required on the bottom of the Raspberry Pi board, plus PCB to Raspberry Pi assembly.

Computer Skill Level: Advanced – SSH ACCESS IS HOW YOU CONFIGURE Hamvoip or ASL software.

The kit comes with complete with online instructions on how to connect the hat.

What you’ll need to supply to build a node:
– Raspberry Pi 3B/3B+ or 4B 1Gb – will not work with the Zero
– Heat sink for the Raspberry Pi processor
– A quality Class 10 Micro SD card, 16Gb or 32Gb
– Genuine Raspberry Pi Power Supply
