SLI-HW: common questions
What microcontroller does the SLI-HW use?
The SLI-HW is built around the STM32F205ZCTx, from the STM32 family.
How big is the SLI-HW PCB?
The SLI-HW measures 90 × 125 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the SLI-HW?
94 components, from 68 distinct parts. The full bill of materials is listed on this page.
Where can I download the SLI-HW design files?
From the dgramop/SLI-HW repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the SLI-HW design in my own project?
Yes, under the terms of its MIT license, which dgramop chose for the repository.
Can I test firmware for the SLI-HW 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.
