About the CaelusPCBCopy PCB
CaelusPCBCopy is an open source NXP PCB design by CaelusRocketry, published on GitHub. It is a 2-layer board measuring 209.1 × 137.2 mm, with 52 components from 6 distinct parts.
Its main chip is the Teensy3.6, from the NXP family. Other key parts include the MAX31850, SerialScrewTerminals, L7805 and LoadCellAmp. By type, the board carries 51 ICs and 1 battery holder.
From the project
Source code for our rocket's launch box.
1.) -.lib: Looks like CaelusPCB.lib or Launchbox.lib These are our stable global project libraries, meaning that they are like the framework for all components in all projects
2.) -cache.lib When you copy a project directory, its -cache.lib file is copied with it. If you make changes to the schematic, for example adding a new component, the local -cache.lib file will update. The -cache.lib of the copied project remains the same, and this is how we do version control. You don't need to really know how this process works or why its important. You just need to know that you add components to…

CaelusPCBCopy: common questions
What microcontroller does the CaelusPCBCopy use?
The CaelusPCBCopy is built around the Teensy3.6, from the NXP family.
How big is the CaelusPCBCopy PCB?
The CaelusPCBCopy measures 209.1 × 137.2 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the CaelusPCBCopy?
52 components, from 6 distinct parts. The full bill of materials is listed on this page.
Where can I download the CaelusPCBCopy design files?
From the CaelusRocketry/launch-box repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the CaelusPCBCopy design in my own project?
The repository has no license, so all rights stay with CaelusRocketry. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the CaelusPCBCopy without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
