Impeller18: common questions
What microcontroller does the Impeller18 use?
The Impeller18 is built around the STM32F427ZGTx, from the STM32 family.
How big is the Impeller18 PCB?
The Impeller18 measures 236.1 × 156.9 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Impeller18?
750 components, from 96 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 Impeller18 design files?
From the buglalis/degree 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 Impeller18 design in my own project?
The repository has no license, so all rights stay with buglalis. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Impeller18 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.
