Allcolours prelastchanges: common questions

What microcontroller does the Allcolours prelastchanges use?

The Allcolours prelastchanges is built around the STM32F103CBTX, from the STM32 family.

How big is the Allcolours prelastchanges PCB?

The Allcolours prelastchanges measures 101.3 × 106.2 mm and is 1.6002 mm thick.

How many components are on the Allcolours prelastchanges?

237 components, from 49 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 Allcolours prelastchanges design files?

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

Can I use the Allcolours prelastchanges design in my own project?

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

Can I test firmware for the Allcolours prelastchanges 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.
