PiCar Hat: common questions
What microcontroller does the PiCar Hat use?
The PiCar Hat is built around the Raspberry_Pi_2_3, from the Raspberry Pi family.
How big is the PiCar Hat?
The PiCar Hat measures 75 × 56 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the PiCar Hat?
40 components, from 25 distinct parts. The full bill of materials is listed on this page.
Where can I download the PiCar Hat design files?
From the dannyandreev/TheLittleRascal-Electrical repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the PiCar Hat design in my own project?
Yes, under the terms of its MIT license, which dannyandreev chose for the repository.
Can I test firmware for the PiCar Hat without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
