Blackmagic isolated: common questions

What microcontroller does the Blackmagic isolated use?

The Blackmagic isolated is built around the STM32F103C, from the STM32 family.

How big is the Blackmagic isolated PCB?

The Blackmagic isolated measures 50 × 32 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Blackmagic isolated?

64 components, from 26 distinct parts. The full bill of materials is listed on this page.

Where can I download the Blackmagic isolated design files?

From the mattbrejza/blackmagic-isolated repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Blackmagic isolated design in my own project?

Yes, under the terms of its MIT license, which mattbrejza chose for the repository.

Can I test firmware for the Blackmagic isolated 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.
