# LinHT-hw
|
||||
Linux-based, SDR handheld transceiver. [OpenHT](https://github.com/M17-Project/OpenHT-hw) successor with greatly simplified hardware - no FPGAs involved.
|
||||
Open-source hardware, Linux-based, SDR handheld transceiver. [OpenHT](https://github.com/M17-Project/OpenHT-hw) successor with greatly simplified hardware - no FPGAs involved.
|
||||
This project offers a replacement board for the Retevis C62 radio, greatly expanding its capabilities.
|
||||
|
||||
## Hardware
|
||||
The device uses an [MCM-iMX93](https://www.compulab.com/products/computer-on-modules/mcm-imx93-nxp-i-mx-93-som-smd-system-on-module) System on Module (SoM) running Linux. The RF front-end is based on the [Semtech SX1255](https://www.semtech.com/products/wireless-rf/lora-core/sx1255). The chip is used as a complete IQ modulator/demodulator, allowing for true all-mode support.
|
||||
|
||||
### Resources
|
||||
**CPU:**
|
||||
- Dual-core ARM Cortex-A55 @ 1.7GHz
|
||||
- ARM Cortex-M33 coprocessor @ 250MHz
|
||||
- Floating Point Unit
|
||||
- ARM Ethos U-65 microNPU (Neural Processing Unit with Tensor Flow Lite support)
|
||||
|
||||
**Memory:**
|
||||
- 2GB LPDDR4
|
||||
- 64GB eMMC
|
||||
|
||||
**RF:**
|
||||
- 500kHz bandwidth complete IQ transceiver
|
||||
|
||||
## Software
|
||||
Developers can use C/C++/Python as well as (or in conjunction with) GNU Radio flowgraphs. Tools such as gcc are built-in. The Linux image will be published later.
|
||||
|
||||
### Supported modes (so far):
|
||||
* M17 - transmission and reception,
|
||||
* TETRA - reception only,
|
||||
* Demo 64QAM transmission at 2Mbps
|
||||
|
||||
Other modes can be added later.
|
||||
|
||||
## Hardware
|
||||
Work in progress. The device will use a System on Module (SoM) running Linux. The RF transceiver used is [Semtech SX1255](https://www.semtech.com/products/wireless-rf/lora-core/sx1255).
|
||||
|
||||
## Software
|
||||
The Linux image will be published later.
|
||||
Other modes can be added later (analog FM/AM/SSB, FreeDV, APRS, etc.).
