12to5Buckconverter: common questions

What microcontroller does the 12to5Buckconverter use?

The 12to5Buckconverter is built around the ATMEGA328P-AU, from the AVR/Arduino family.

How big is the 12to5Buckconverter PCB?

The 12to5Buckconverter measures 35 × 31 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 12to5Buckconverter?

15 components, from 15 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 12to5Buckconverter design files?

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

Can I use the 12to5Buckconverter design in my own project?

Yes, under the terms of its BSD-3-Clause license, which hwreverse chose for the repository.

Can I test firmware for the 12to5Buckconverter 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.
