Comm rfb: common questions
What microcontroller does the Comm rfb use?
The Comm rfb is built around the C81787, from the STM32 family.
How big is the Comm rfb PCB?
The Comm rfb measures 90.2 × 95.9 mm, has 4 copper layers and is 4.69 mm thick.
How many components are on the Comm rfb?
53 components, from 38 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 Comm rfb design files?
From the queens-satellite-team/pcbs 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 Comm rfb design in my own project?
The repository has no license, so all rights stay with queens-satellite-team. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Comm rfb without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
