Management: common questions

What microcontroller does the Management use?

The Management is built around the NRF52840_ITSY_BITSY, from the Nordic nRF family.

How big is the Management PCB?

The Management measures 101 × 31.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Management?

50 components, from 27 distinct parts. The full bill of materials is listed on this page.

Where can I download the Management design files?

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

Can I use the Management design in my own project?

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

Can I test firmware for the Management without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Nordic nRF firmware against it before you order a PCB.
