Teensy4.1: common questions

What microcontroller does the Teensy4.1 use?

The Teensy4.1 is built around the TEENSY 4.1, from the NXP family.

How big is the Teensy4.1 PCB?

The Teensy4.1 measures 120 × 85 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Teensy4.1?

37 components, from 11 distinct parts. The full bill of materials is listed on this page.

Where can I download the Teensy4.1 design files?

From the Krishnapriya1711/pcb repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Teensy4.1 design in my own project?

The repository has no license, so all rights stay with Krishnapriya1711. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Teensy4.1 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.
