Hardware Projects
The following projects are hardware projects developed and published by the M17 team:
| Project | Description | Image | Status |
|---|---|---|---|
| LinHT | Open-source hardware, Linux-based, SDR handheld transceiver. OpenHT successor with greatly simplified hardware - no FPGAs involved. This project offers a replacement board for the Retevis C62 radio, greatly expanding its capabilities. Users can define their radios' capabilities using GNU Radio. |  |
In development. |
| OpenHT | An open-source, SDR handheld transceiver, capable of supporting virtually any mode (including M17 and FreeDV). It is built around the AT86RF215 chip by Microchip/Atmel and LIFCL-40-9SG72C FPGA from Lattice as a shield for 32F469IDISCOVERY. |  |
Development halted - superseded by LinHT (see above). |
| M17_3310 | A PCB that can be installed in an old Nokia 3310 instead of the original mainboard. This board enables FM/FSK/M17 communication on the 70cm band and turns the good old 3310 into an interesting toy in conjunction with the M17 project. |  |
Hardware development halted. Usable sample firmware. |
| Module 17 1.0 | A standalone modem that transforms any 9600 baud capable transceiver into an M17 compatible radio. It is based on a STM32F4 microcontroller and is designed to run the OpenRTX firmware. |  |
Mature release. |
| CC1200 HAT | The CC1200 RF Raspberry Pi Zero shield. Supported by the rpi-interface, rpi-dashboard and the m17-gateway |  |
Hardware ready. Actively developed firmware, mature release. |
| SX1255 HAT | Raspberry Pi Zero shield with the SX1255 RF transceiver chip. |  |
Hardware ready. Mature release. |
| SX1255 PMOD board | Minimalistic evaluation board for the SX1255 RF transceiver chip, with PMOD connectors. |  |
Mature release. |
| Micro17 | An M17 modem for certain ICOM families of radios designed to run the OpenRTX firmware. |  |
Development halted. |
| Remote Radio Unit | An enclosed, UHF radio transceiver with baseband and control interfaces exposed over optical fiber, allowing for remote control. |  |
In development. |
