Wrectangle-V4-old: common questions
What microcontroller does the Wrectangle-V4-old use?
The Wrectangle-V4-old is built around the STM32F405RGTX, from the STM32 family.
How big is the Wrectangle-V4-old PCB?
The Wrectangle-V4-old measures 60 × 100 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Wrectangle-V4-old?
135 components, from 89 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 Wrectangle-V4-old design files?
From the Wildcat-Rocket-Engineering-Club/WRECtangle repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Wrectangle-V4-old design in my own project?
The repository has no license, so all rights stay with Wildcat-Rocket-Engineering-Club. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Wrectangle-V4-old 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.
