Nanoradio: common questions
What microcontroller does the Nanoradio use?
The Nanoradio is built around the CH32V003JxMx, from the RISC-V family.
How big is the Nanoradio PCB?
The Nanoradio measures 38.1 × 30.2 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Nanoradio?
26 components, from 17 distinct parts. The full bill of materials is listed on this page.
Where can I download the Nanoradio design files?
From the ibuki2003/nanoradio repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Nanoradio design in my own project?
The repository has no license, so all rights stay with ibuki2003. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Nanoradio without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RISC-V firmware against it before you order a PCB.
