About the Software-Defined-Radio PCB

Software-Defined-Radio is an open source AVR/Arduino PCB design by Dizzerin, published on GitHub. It is a 2-layer board measuring 81.3 × 33.7 mm, with 62 components from 37 distinct parts.

Its main chip is the Arduino_Nano_v3.x, from the AVR/Arduino family. Other key parts include the Si5351A-B-GT, SN74CBT3253 and LM4562. By type, the board carries 18 capacitors, 15 resistors, 10 connectors, 5 transistors, 4 jumpers and 3 ICs.

It belongs with the rf & radio and audio designs in this gallery.

From the project

Quadrature sampling down converter software defined radio

1. Simple Design: We wanted our design to be easy to understand and construct 2. Ease of Construction: We wanted to build a simple radio that works 3. Low Cost: Our budget for this project was $30

Note: Overview section by Konrad McClure

Note: This Theory Section is a slightly modified version of work originally written by Konrad McClure

To get Quisk up and running with our radio, simply: 1. Flash the openradioquisk.ino file to the arduino nano microcontroller. 2. Start Quisk and configure a new radio. Point Quisk to the quiskconfopenradio.py file. Alternatively you can simply copy the…

Software-Defined-Radio: common questions

What microcontroller does the Software-Defined-Radio use?

The Software-Defined-Radio is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.

How big is the Software-Defined-Radio PCB?

The Software-Defined-Radio measures 81.3 × 33.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Software-Defined-Radio?

62 components, from 37 distinct parts. The full bill of materials is listed on this page.

Where can I download the Software-Defined-Radio design files?

From the Dizzerin/Software-Defined-Radio repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Software-Defined-Radio design in my own project?

The repository has no license, so all rights stay with Dizzerin. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Software-Defined-Radio without the hardware?

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