MagicStick: common questions
What microcontroller does the MagicStick use?
The MagicStick is built around the STM32L433CCT6, from the STM32 family.
How big is the MagicStick PCB?
The MagicStick measures 259.1 × 13.5 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the MagicStick?
112 components, from 59 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 MagicStick design files?
From the Kreyl/MagicStick repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the MagicStick design in my own project?
The repository has no license, so all rights stay with Kreyl. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the MagicStick 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.
