RascalHat: common questions

What microcontroller does the RascalHat use?

The RascalHat is built around the Raspberry_Pi_2_3, from the Raspberry Pi family.

How big is the RascalHat PCB?

The RascalHat measures 10.7 × 14.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the RascalHat?

51 components, from 27 distinct parts. The full bill of materials is listed on this page.

Where can I download the RascalHat design files?

From the dannyandreev/TheLittleRascal-Electrical repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the RascalHat 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 RascalHat 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.
