ORCA CORE A design files

The KiCad project lives in the UEC-RMF-Rescue/ORCA_board repository on GitHub; these links point at the commit this page was built from.

ORCA CORE A: common questions

What microcontroller does the ORCA CORE A use?

The ORCA CORE A is built around the RASPBERRY_PI_2_3, from the Raspberry Pi family.

How big is the ORCA CORE A PCB?

The ORCA CORE A measures 99 × 99 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ORCA CORE A?

96 components, from 44 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 CORE A design files?

From the UEC-RMF-Rescue/ORCA_board repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the ORCA CORE A design in my own project?

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

Can I test firmware for the ORCA CORE A 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.
