dodekaedrin muotoinen radio ":D" / dodecahedron shaped radio ":D"

This project aims to create truly affordable (<50€) 40m SSB QRP HAM radio kit. Intention is to create such easy-approach kit that enables new (and old) HAMs to learn about radios, electronics and so on.

Some intended specs include:

  • included SWR-meter
  • ~5-10W of raw electromagnetic power
  • graphical UI
  • 2 mixer stages, one physical, one done with software

(Antenna not included)

Questions

How big is the Dodekaedri PCB?

It measures 76.2 × 76.2 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Dodekaedri use?

227 parts, built around the BA891, MCP6L02-E/SN, 74LVC1G3157 and SI5351A-B-GT. 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 Dodekaedri KiCad files?

From the e-xla/dodekaedri repository on GitHub, at the commit this page was made from: the board is hardware/dodekaedri.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Dodekaedri design in my own project?

Its repository states no licence, so its author keeps all rights: ask e-xla before reusing the design.
