From the project

V/U/SHF and QO-100 SDR Transceiver Project

This project is a SDR receiver transceiver project initiated to have a portable QO-100 Satellite ground station which can receiver on 739 MHz (direct output of a standard TV LNB) and transmit on 2.4 GHz QO-100 uplink frequency. The basic idea of the SDR is based on Arjante Marvelde's implementation of Guido's uSDX implementation on raspberry pi pico (https://github.com/ArjanteMarvelde/uSDR-pico/).

QO100 RX: common questions

What microcontroller does the QO100 RX use?

The QO100 RX is built around the RP2040_PICO, from the RP2040/RP2350 family.

How big is the QO100 RX PCB?

The QO100 RX measures 97 × 97 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the QO100 RX?

162 components, from 63 distinct parts. The full bill of materials is listed on this page.

Where can I download the QO100 RX design files?

From the barisdinc/N3B_SDR_Transceiver_HW repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the QO100 RX design in my own project?

Yes, under the terms of its GPL-3.0 license, which barisdinc chose for the repository.

Can I test firmware for the QO100 RX without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
