Black rhino: common questions
What microcontroller does the Black rhino use?
The Black rhino is built around the ATmega32U4-AU, from the AVR/Arduino family.
How big is the Black rhino PCB?
The Black rhino measures 271.5 × 109.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Black rhino?
147 components, from 16 distinct parts. The full bill of materials is listed on this page.
Where can I download the Black rhino design files?
From the KingMalur/Keyboards repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Black rhino design in my own project?
The repository has no license, so all rights stay with KingMalur. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Black rhino 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.
