Rev2.2: common questions
What microcontroller does the Rev2.2 use?
The Rev2.2 is built around the C84808, from the STM32 family.
How big is the Rev2.2 PCB?
The Rev2.2 measures 91.8 × 94.5 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Rev2.2?
114 components, from 52 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 Rev2.2 design files?
From the WilliamLim781/PCB_practice 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 Rev2.2 design in my own project?
The repository has no license, so all rights stay with WilliamLim781. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Rev2.2 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.
