SDRBackup2: common questions

What microcontroller does the SDRBackup2 use?

The SDRBackup2 is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.

How big is the SDRBackup2 PCB?

The SDRBackup2 measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SDRBackup2?

76 components, from 43 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 SDRBackup2 design files?

From the KonradMcClure/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 SDRBackup2 design in my own project?

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

Can I test firmware for the SDRBackup2 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.
