MCL65+: common questions

What microcontroller does the MCL65+ use?

The MCL65+ is built around the Teensy4.1, from the NXP family.

How big is the MCL65+ PCB?

The MCL65+ measures 72.6 × 64.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the MCL65+?

6 components, from 5 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 MCL65+ design files?

From the MicroCoreLabs/Projects repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the MCL65+ design in my own project?

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

Can I test firmware for the MCL65+ 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.
