R1 panel: common questions
What microcontroller does the R1 panel use?
The R1 panel is built around the STM32F405RxTx, from the STM32 family.
How big is the R1 panel PCB?
The R1 panel measures 50 × 50 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the R1 panel?
176 components, from 82 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 R1 panel design files?
From the cuspaceflight/m3-avionics repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the R1 panel design in my own project?
The repository has no license, so all rights stay with cuspaceflight. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the R1 panel 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.
