CARL-Air-Brake-Power-Supply-Hardware: common questions

What microcontroller does the CARL-Air-Brake-Power-Supply-Hardware use?

The CARL-Air-Brake-Power-Supply-Hardware is built around the ATmega328P-AU, from the AVR/Arduino family.

How big is the CARL-Air-Brake-Power-Supply-Hardware PCB?

The CARL-Air-Brake-Power-Supply-Hardware measures 65 × 56 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the CARL-Air-Brake-Power-Supply-Hardware?

86 components, from 33 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 CARL-Air-Brake-Power-Supply-Hardware design files?

From the Kenneth-Goveas/CARL-Air-Brake-Power-Supply-Hardware repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the CARL-Air-Brake-Power-Supply-Hardware design in my own project?

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

Can I test firmware for the CARL-Air-Brake-Power-Supply-Hardware 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.
