About the Radio Interface PCB

Radio Interface is an open source PCB design by Arkos-Engineering, published on GitHub. It is a 2-layer board measuring 31.5 × 18.5 mm, with 10 components from 6 distinct parts.

Other key parts include the C5379863. By type, the board carries 4 transistors, 3 resistors, 2 capacitors and 1 IC.

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

From the project

We can split this out into separate repos later, right now its very convenient to have everything here.

What will set this radio apart from competitors is:

Fully open source, hardware and software Swappable radio module, allowing easy hardware upgradability (2M/70CM at launch) USBC charge and data, SD card, Kenwood style audio connector, removable battery Low-power E-ink display targeting 72+ hour standby time FM and M17 support at launch, with plans to support many other digital modes in the future such as DMR, P25 (depending on codec licensing) Ability for community to write and easily install “apps” that allow custom features or arbitrary digital mode development Usable “off the shelf”. We…

Radio Interface: common questions

How big is the Radio Interface PCB?

The Radio Interface measures 31.5 × 18.5 mm, has 2 copper layers and is 1 mm thick.

How many components are on the Radio Interface?

10 components, from 6 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 Radio Interface design files?

From the Arkos-Engineering/HT-15_hardware repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Radio Interface design in my own project?

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