Ledboad: common questions

What microcontroller does the Ledboad use?

The Ledboad is built around the STM32G070CBTX, from the STM32 family.

How big is the Ledboad PCB?

The Ledboad measures 100 × 30.8 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Ledboad?

302 components, from 15 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Ledboad design files?

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

Can I use the Ledboad design in my own project?

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

Can I test firmware for the Ledboad 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.
