Allcolours analogue: common questions
What microcontroller does the Allcolours analogue use?
The Allcolours analogue is built around the STM32F446RET6, from the STM32 family.
How big is the Allcolours analogue PCB?
The Allcolours analogue measures 163.1 × 128.8 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Allcolours analogue?
240 components, from 101 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 analogue 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 analogue 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 analogue 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.
