 # 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.).
