MagicWand: common questions

What microcontroller does the MagicWand use?

The MagicWand is built around the stm32f072c8t6, from the STM32 family.

How big is the MagicWand PCB?

The MagicWand measures 115.5 × 14.4 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the MagicWand?

83 components, from 45 distinct parts. The full bill of materials is listed on this page.

Where can I download the MagicWand design files?

From the Kreyl/MagicWand repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the MagicWand 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 MagicWand 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.
