ORCA Control Board: common questions

What microcontroller does the ORCA Control Board use?

The ORCA Control Board is built around the NUCLEO-L432KC, from the AVR/Arduino family.

How big is the ORCA Control Board?

The ORCA Control Board measures 99.1 × 99.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ORCA Control Board?

64 components, from 25 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 ORCA Control Board design files?

From the LukeDWaller99/MEng-a-boys 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 ORCA Control Board design in my own project?

The repository has no license, so all rights stay with LukeDWaller99. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the ORCA Control Board 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.
