MorseCodeWatch: common questions

What microcontroller does the MorseCodeWatch use?

The MorseCodeWatch is built around the NRF52832-QFAA, from the Nordic nRF family.

How big is the MorseCodeWatch PCB?

The MorseCodeWatch measures 28.2 × 34.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the MorseCodeWatch?

46 components, from 33 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 MorseCodeWatch design files?

From the bnezuld/MorseCodeWatchPCB repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the MorseCodeWatch design in my own project?

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

Can I test firmware for the MorseCodeWatch 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.
