Fannyadams: common questions
What microcontroller does the Fannyadams use?
The Fannyadams is built around the STM32F405R, from the STM32 family.
How big is the Fannyadams PCB?
The Fannyadams measures 154.9 × 102.9 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Fannyadams?
300 components, from 98 distinct parts. The full bill of materials is listed on this page.
Where can I download the Fannyadams design files?
From the svofski/fannyadams repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Fannyadams design in my own project?
The repository has no license, so all rights stay with svofski. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Fannyadams 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.
