About the SDR Reciever PCB

SDR Reciever is an open source AVR/Arduino PCB design by greenjacketgirl, published on GitHub. It is a 2-layer board measuring 94.9 × 72.8 mm, with 120 components from 69 distinct parts.

Its main chip is the Arduino Nano V3, from the AVR/Arduino family. Other key parts include the FST3253, Si5351A-B-GT, SN74ACT74DR and LT6231. By type, the board carries 36 capacitors, 28 resistors, 21 test points, 12 inductors, 7 ICs and 5 jumpers.

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

From the project

This project is an attempt at designing and building a Software Defined Radio receiver that has the capabilities of listening to frequencies ranging from 500kHz to 50MHz utlizing the board designed, a sound card, and Quisk coupled with arduino code.

This folder contains two versions of the schematic and pcb design. The first design is the collection of files shown. The second revision is located in the folder Kicad-V2. This second revision is the schematic updated with the corrections made by hand shown in the Issues tab. Note that this second revision only has an updated schematic, not an updated pcb. Thus, future work will require further revision of the PCB.

SDR Reciever: common questions

What microcontroller does the SDR Reciever use?

The SDR Reciever is built around the Arduino Nano V3, from the AVR/Arduino family.

How big is the SDR Reciever PCB?

The SDR Reciever measures 94.9 × 72.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SDR Reciever?

120 components, from 69 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the SDR Reciever design files?

From the greenjacketgirl/SDR_Receiver repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the SDR Reciever design in my own project?

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

Can I test firmware for the SDR Reciever 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.
