Chonc60: common questions

What microcontroller does the Chonc60 use?

The Chonc60 is built around the MDBT50Q-1MV2, from the Nordic nRF family.

How big is the Chonc60 PCB?

The Chonc60 measures 297 × 132 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Chonc60?

356 components, from 29 distinct parts. The full bill of materials is listed on this page.

Where can I download the Chonc60 design files?

From the mildlyfunctionalgays/chonc60 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Chonc60 design in my own project?

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

Can I test firmware for the Chonc60 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Nordic nRF firmware against it before you order a PCB.
