GyroLed2: common questions
What microcontroller does the GyroLed2 use?
The GyroLed2 is built around the STM32L031G6Ux, from the STM32 family.
How big is the GyroLed2 PCB?
The GyroLed2 measures 24.5 × 29.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the GyroLed2?
22 components, from 13 distinct parts. The full bill of materials is listed on this page.
Where can I download the GyroLed2 design files?
From the smariel/GyroLed2 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the GyroLed2 design in my own project?
Yes, under the terms of its CERN-OHL-W-2.0 license, which smariel chose for the repository.
Can I test firmware for the GyroLed2 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.
