Bike oshpark: common questions

What microcontroller does the Bike oshpark use?

The Bike oshpark is built around the ATTINYXX-20PU, from the AVR/Arduino family.

How big is the Bike oshpark PCB?

The Bike oshpark measures 45.7 × 50.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Bike oshpark?

21 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the Bike oshpark design files?

From the eliassjogreen/BiKe repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

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

Yes, under the terms of its MIT license, which eliassjogreen chose for the repository.

Can I test firmware for the Bike oshpark without the hardware?

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