Polaron: common questions
What microcontroller does the Polaron use?
The Polaron is built around the Teensy3.6, from the NXP family.
How big is the Polaron PCB?
The Polaron measures 157.5 × 116 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Polaron?
71 components, from 10 distinct parts. The full bill of materials is listed on this page.
Where can I download the Polaron design files?
From the zueblin/Polaron repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Polaron design in my own project?
The repository has no license, so all rights stay with zueblin. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Polaron 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.
