SHARI PiHat is a ham construction project that implements a Raspberry Pi hosted Allstar node using a NiceRF SA818 embedded UHF (420 – 450 MHz) or VHF (144-148 MHz) radio module. The PC board use a slightly modified PiHat form factor which plugs into the GPIO connector on a Raspberry Pi4 so the Allstar node is contained in a single enclosure. Options include:

• VHF (2 meters) or UHF (70 cm)
• External fan

SHARI  PiHat (52PI Case) is a ham construction project that implements a Pi4B hosted Allstar node using a NiceRF SA818 embedded UHF (420 – 450 MHz) or a VHF (144-148 MHz) radio module.  The radio module and interface circuits are located on a custom Raspberry Pi Hat board.   This Pi Hat board plugs into the Pi4B using the 40 pin GPIO connector. A JST 2 conducter cable is used to complete a USB connection to the PI4B. This case includes an internal fan. The RF signal is routed to the antenna using a coax cable assembly to allow alternate antenna locations to be used. A complete Allstar node can be created with a SHARI PiHat 52PI Case kit, a Raspberry Pi4B (with power supply and microSD card) and an Allstar image.

SHARI PiHat (Unistorm Case) is a ham construction project that implements a Raspberry Pi hosted Allstar node using a NiceRF SA818 embedded UHF (420 – 450 MHz) or VHF (144-148 MHz) radio module. This case allows the use of a Raspberry Pi3 or Pi4 server. The PC board conforms to the PiHat form factor. It plugs into the GPIO connector on a Raspberry Pi so the Allstar node is contained in a single enclosure. Options include:

• VHF (2 meters) or UHF (70 cm)
• Raspberry Pi3 or Pi4
• External fan
• Straight or right-angle antenna

SHARI PiZero is a ham construction project that implements a Raspberry PiZero 2W hosted Allstar node using a NiceRF SA818 embedded UHF (420 – 450 MHz) or VHF (144-148 MHz) radio module. The PiZero is a daughter board which plugs into the SHARI motherboard via the Pi GPIO connector. The SHARI motherboard contains a USB hub providing three external microB USB ports. An internal plug-in cable connects the PiZero USB port to the SHARI motherboard.

DINAH (DIN connector based Allstar interface for Hams) is a kit construction project that implements a radio interface to a Raspberry Pi running Allstar software.  DINAH plugs into a USB jack on a Raspberry Pi. A standard 6 pin miniDIN cable connects DINAH to any radio with a 6 pin miniDIN packet interface (also called a data interface).

BRIAN (SM) (Baofeng BF-88S Radio Interface to the Allstar Network) is a kit construction project that implements a Raspberry Pi hosted Allstar node using the circuit board and other parts from a Baofeng BF-888S as the node radio operating in the amateur UHF (70 cm) band. BRIAN connects to a Raspberry Pi using a short USB cable.

PAUL (Packet and Allstar Universal Link) is a kit construction project that implements a radio interface to a Raspberry Pi running Allstar software.  PAUL plugs into a USB jack on a Raspberry Pi using a USB A to Mini B cable. A standard DE9 connector (9 pin dsub) with typical TNC pinout is used for I/O to the radio. COS and PTT utilize optically coupled solid state relays.
