Blinky: common questions

What microcontroller does the Blinky use?

The Blinky is built around the STM32G030C6Tx, from the STM32 family.

How big is the Blinky PCB?

The Blinky measures 50 × 50 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Blinky?

83 components, from 18 distinct parts. The full bill of materials is listed on this page.

Where can I download the Blinky design files?

From the rcls/blinky repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Blinky design in my own project?

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

Can I test firmware for the Blinky 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.
