SCO68R: common questions

What microcontroller does the SCO68R use?

The SCO68R is built around the STM32F103C8Tx, from the STM32 family.

How big is the SCO68R PCB?

The SCO68R has 2 copper layers and is 1.6 mm thick.

How many components are on the SCO68R?

190 components, from 21 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 SCO68R design files?

From the scottcjx/SCO68R 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 SCO68R design in my own project?

Yes, under the terms of its GPL-3.0 license, which scottcjx chose for the repository.

Can I test firmware for the SCO68R 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.

Earlier revisions in the repo: SCO68R_V1, SCO68R
