KiKard old: common questions

What microcontroller does the KiKard old use?

The KiKard old is built around the NRF52840-QIAA-R, from the Nordic nRF family.

How big is the KiKard old PCB?

The KiKard old measures 40 × 70 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the KiKard old?

70 components, from 30 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 KiKard old design files?

From the m5kro/KiKard-old 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 KiKard old design in my own project?

The repository has no license, so all rights stay with m5kro. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the KiKard old 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.
