Krieger: common questions
What microcontroller does the Krieger use?
The Krieger is built around the STM32F446RETx, from the STM32 family.
How big is the Krieger PCB?
The Krieger measures 80 × 47 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Krieger?
33 components, from 19 distinct parts. The full bill of materials is listed on this page.
Where can I download the Krieger design files?
From the tk20dk/krieger repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Krieger design in my own project?
Yes, under the terms of its MIT license, which tk20dk chose for the repository.
Can I test firmware for the Krieger 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.
