TeensyOpenLoop: common questions
What microcontroller does the TeensyOpenLoop use?
The TeensyOpenLoop is built around the Teensy4.1, from the NXP family.
How big is the TeensyOpenLoop PCB?
The TeensyOpenLoop measures 111.1 × 86 mm, has 2 copper layers and is 1.600198 mm thick.
How many components are on the TeensyOpenLoop?
21 components, from 11 distinct parts. The full bill of materials is listed on this page.
Where can I download the TeensyOpenLoop design files?
From the neurorishika/MultiBiOS repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the TeensyOpenLoop design in my own project?
Yes, under the terms of its MIT license, which neurorishika chose for the repository.
Can I test firmware for the TeensyOpenLoop 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.
