KiCAD PCB files for KiwiSDR project including active antenna and bias tee

Software-defined Radio (SDR) and GPS for the BeagleBone Black ----------------------------------------------------------------------

An add-on board ("cape") that turns your Beagle into a web-accessible shortwave receiver.

This repository contains the KiCAD files (schematics, board layout), Gerbers, BOM and other files used to produce the KiwiSDR PCB. Also included here is the design for an active antenna and bias tee although they are still undergoing development.

Pwr: common questions

How big is the Pwr PCB?

The Pwr measures 99 × 60 mm and is 1.6 mm thick.

How many components are on the Pwr?

61 components, from 29 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 Pwr design files?

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

Can I use the Pwr design in my own project?

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