Bike PWR2: common questions

What microcontroller does the Bike PWR2 use?

The Bike PWR2 is built around the MDBT42V-512KV2, from the Nordic nRF family.

How big is the Bike PWR2 PCB?

The Bike PWR2 measures 45 × 45 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Bike PWR2?

48 components, from 18 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 Bike PWR2 design files?

From the derdds/Esit-Internship repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Bike PWR2 design in my own project?

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

Can I test firmware for the Bike PWR2 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.
