Small: common questions

What microcontroller does the Small use?

The Small is built around the STM32G070KBT6, from the STM32 family.

How big is the Small PCB?

The Small measures 110 × 95.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Small?

86 components, from 33 distinct parts. The full bill of materials is listed on this page.

Where can I download the Small design files?

From the atelier-lyon/Epiled_slaves repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Small design in my own project?

The repository has no license, so all rights stay with atelier-lyon. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Small 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.
