SpyThing-Hardware: common questions
What microcontroller does the SpyThing-Hardware use?
The SpyThing-Hardware is built around the STM32L476RG, from the STM32 family.
How big is the SpyThing-Hardware PCB?
The SpyThing-Hardware measures 61 × 46 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the SpyThing-Hardware?
67 components, from 36 distinct parts. The full bill of materials is listed on this page.
Where can I download the SpyThing-Hardware design files?
From the villetiukuvaara/SpyThing-Hardware repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the SpyThing-Hardware design in my own project?
Yes, under the terms of its GPL-3.0 license, which villetiukuvaara chose for the repository.
Can I test firmware for the SpyThing-Hardware 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.
