ORCA CORE: common questions
What microcontroller does the ORCA CORE use?
The ORCA CORE is built around the RASPBERRY_PI_2_3, from the Raspberry Pi family.
How big is the ORCA CORE PCB?
The ORCA CORE measures 99 × 94 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the ORCA CORE?
182 components, from 75 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 design files?
From the UEC-RMF-Rescue/ORCA_board 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 CORE 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 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.
