Obiwanstenobit: common questions

What microcontroller does the Obiwanstenobit use?

The Obiwanstenobit is built around the ProMicro, from the AVR/Arduino family.

How big is the Obiwanstenobit PCB?

The Obiwanstenobit measures 93.8 × 98.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Obiwanstenobit?

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

Where can I download the Obiwanstenobit design files?

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

Can I use the Obiwanstenobit design in my own project?

Yes, under the terms of its CERN-OHL-S-2.0 license, which ivndbt chose for the repository.

Can I test firmware for the Obiwanstenobit 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.
