CNTRL: common questions
What microcontroller does the CNTRL use?
The CNTRL is built around the STM32405RGT6, from the STM32 family.
How big is the CNTRL PCB?
The CNTRL measures 78 × 78 mm, has 4 copper layers and is 1.58 mm thick.
How many components are on the CNTRL?
126 components, from 59 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 CNTRL design files?
From the Arav0001/navion-dev 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 CNTRL design in my own project?
Yes, under the terms of its MIT license, which Arav0001 chose for the repository.
Can I test firmware for the CNTRL 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.
