Skadi 6 bay: common questions

What microcontroller does the Skadi 6 bay use?

The Skadi 6 bay is built around the STM32F103C8Tx, from the STM32 family.

How big is the Skadi 6 bay PCB?

The Skadi 6 bay has 2 copper layers and is 1.6 mm thick.

How many components are on the Skadi 6 bay?

106 components, from 51 distinct parts. The full bill of materials is listed on this page.

Where can I download the Skadi 6 bay design files?

From the M0RCHED/skadi_6_bay repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Skadi 6 bay design in my own project?

Yes, under the terms of its Apache-2.0 license, which M0RCHED chose for the repository.

Can I test firmware for the Skadi 6 bay 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.
