GSLeaf: common questions
What microcontroller does the GSLeaf use?
The GSLeaf is built around the STM32L476Rx, from the STM32 family.
How big is the GSLeaf PCB?
The GSLeaf measures 30 × 103 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the GSLeaf?
115 components, from 49 distinct parts. The full bill of materials is listed on this page.
Where can I download the GSLeaf design files?
From the Kreyl/GardenOfShadows repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the GSLeaf 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 GSLeaf 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.
