Diseqc cntrl: common questions

What microcontroller does the Diseqc cntrl use?

The Diseqc cntrl is built around the STM32F407VGT6, from the STM32 family.

How big is the Diseqc cntrl PCB?

The Diseqc cntrl measures 90 × 100 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the Diseqc cntrl?

121 components, from 62 distinct parts. The full bill of materials is listed on this page.

Where can I download the Diseqc cntrl design files?

From the getpwnam/diseqc_cntrl repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Diseqc cntrl design in my own project?

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

Can I test firmware for the Diseqc 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.
