STDC: common questions
What microcontroller does the STDC use?
The STDC is built around the STM32L476RGTx, from the STM32 family.
How big is the STDC PCB?
The STDC measures 38 × 48 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the STDC?
120 components, from 50 distinct parts. The full bill of materials is listed on this page.
Where can I download the STDC design files?
From the SebastianThomas/STDC-PCB repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the STDC design in my own project?
The repository has no license, so all rights stay with SebastianThomas. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the STDC 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.
