Phoenix main board: common questions
What microcontroller does the Phoenix main board use?
The Phoenix main board is built around the MCP3564, from the Nordic nRF family.
How big is the Phoenix main board?
The Phoenix main board measures 91.9 × 53.2 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Phoenix main board?
107 components, from 51 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 Phoenix main board design files?
From the Phalkon-Industries/phoenix-instrument 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 Phoenix main board design in my own project?
Yes, under the terms of its CERN-OHL-S-2.0 license, which Phalkon-Industries chose for the repository.
Can I test firmware for the Phoenix main board without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Nordic nRF firmware against it before you order a PCB.
