The PiFinder™ uses the Cedar Detect and Cedar Solve libraries by smroid. Cedar Solve is licensed under Apache-2.0.
Cedar Detect is published under the Functional Source License (FSL-1.1-MIT), which permits broad non-commercial use but excludes commercial uses that compete with Cedar Detect. Because the PiFinder™ is also offered commercially, it bundles and distributes the Cedar Detect binaries under a separate license granted expressly by the copyright holder — not under the…

PiFinder: common questions
What microcontroller does the PiFinder use?
The PiFinder is built around the Raspberry_Pi_2_3, from the Raspberry Pi family.
How big is the PiFinder PCB?
The PiFinder measures 87.9 × 57.7 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the PiFinder?
44 components, from 11 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 PiFinder design files?
From the brickbots/PiFinder 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 PiFinder design in my own project?
Yes, under the terms of its GPL-3.0 license, which brickbots chose for the repository.
Can I test firmware for the PiFinder 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.
