CDH: common questions

What microcontroller does the CDH use?

The CDH is built around the 2x DF40C-100DS-0.4V, from the Raspberry Pi family.

How big is the CDH PCB?

The CDH measures 96 × 90 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the CDH?

17 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the CDH design files?

From the coloradocube/balloonsat-bus repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the CDH design in my own project?

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

Can I test firmware for the CDH without the hardware?

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