0bCLK: common questions

What microcontroller does the 0bCLK use?

The 0bCLK is built around the ATmega48A-P, from the AVR/Arduino family.

How big is the 0bCLK PCB?

The 0bCLK measures 72.5 × 40 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 0bCLK?

18 components, from 6 distinct parts. The full bill of materials is listed on this page.

Where can I download the 0bCLK design files?

From the Jvlse/0bCLK repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the 0bCLK design in my own project?

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

Can I test firmware for the 0bCLK 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.
