About the Narrowband-SDR PCB

Narrowband-SDR is an open source PCB design by BillyWoods, published on GitHub. It is a 4-layer board measuring 100 × 100 mm, with 463 components from 39 distinct parts.

Other key parts include the AMS1117-3.3, NB3L553, CY7C68013A-56PVX, 24LC128 and MCP1825S. By type, the board carries 214 capacitors, 194 resistors, 33 ICs, 12 inductors, 5 connectors and 2 crystals.

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

From the project

A four-channel narrowband SDR receiver based around the Mirics MSi001, MAX11131 and FX2LP.

Having libusb installed will also allow the host utility to be compiled.

The open source Sigrok project must be acknowledged for serving as an example of how to use the FX2LP at the core of this SDR for high speed data acquisition. Similarly, the Osmocom project, which provides a driver for the tuners used in this SDR, has assisted with interfacing and configuring the MSi001 tuners used in this project.
