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.

Kiwi: common questions

What microcontroller does the Kiwi use?

The Kiwi is built around the XC7A35T-1FTG256C, from the FPGA family.

How big is the Kiwi PCB?

The Kiwi measures 117 × 55 mm and is 1.6 mm thick.

How many components are on the Kiwi?

166 components, from 59 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 Kiwi 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 Kiwi 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.

Can I test firmware for the Kiwi without the hardware?

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