Overview
Nigun is an open-source printed circuit board by raziele, from the raziele/Nigun repository on GitHub. It is a 4-layer board of 54 × 50.1 mm with 259 parts on 97 nets, routed with 1,301 tracks and 209 vias.
It is built around the MIC5504-3.3YM5-TR. Its parts include 89 capacitors, 32 resistors, 8 ICs, 6 diodes and 5 connectors. It belongs with the radio and wireless boards and the SAM D and SAM boards of this library.
Main components

README.mdNigun (Melody)
RF down-converter for (but not only for) SDR
PURPOSE
Allow low-frequency SDR (mainly RTL-SDR) to recieve wireless signals in frequencies higher than 1500MHz Nigun is platform-independant, so it can be paired with other devices such as YARD stick ONE and PandwaRF too!
MAIN PROPERTIES
- Dynamic LO - LO will be determined by the user and programmed by the MCU
- Almost no filtering - will leave this challenge outside of this project scope
- Power up and programming via micro-usb connector. Should be able to power up from a USB power-pack (but probably not from a computer port)
- Highest RF frequency will be 3GHz
- Product also features a VCO for signal-generation purposes. VCO support should be 200-2700MHz
DESIGN DETAILS
Can be found currently on http://slides.com/raziele/software-define-radio-4-5-6-7-8#/ All details should be updated here in the near future
CURRENT STATUS
2017-05: Finished PCB design. Working on some finishing but I should order first batch during June
CREDITS
- All those who were patient enough to teach, review, and answer my endless questions
- Michele Perla and his HACK project - for the Atmel SAMD21E reference design
LICENSE
I haven't dealt with the licensing part yet, though it will probably be under CERN OHL v. 1.2. For now, please contact me for any licensing request.

Questions
How big is the Nigun PCB?
It measures 54 × 50.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Nigun use?
259 parts, built around the MIC5504-3.3YM5-TR. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Nigun KiCad files?
From the raziele/Nigun repository on GitHub, at the commit this page was made from: the board is Schematics/Nigun.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nigun design in my own project?
Its repository states no licence, so its author keeps all rights: ask raziele before reusing the design.
