POV Fidget: common questions
What microcontroller does the POV Fidget use?
The POV Fidget is built around the SAMD21G18, from the Microchip SAM family.
How big is the POV Fidget PCB?
The POV Fidget measures 71.9 × 65.7 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the POV Fidget?
66 components, from 30 distinct parts. The full bill of materials is listed on this page.
Where can I download the POV Fidget design files?
From the idlehandsdev/POV_Fidget repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the POV Fidget design in my own project?
The repository has no license, so all rights stay with idlehandsdev. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the POV Fidget without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Microchip SAM firmware against it before you order a PCB.
