MCL6809: common questions

What microcontroller does the MCL6809 use?

The MCL6809 is built around the Teensy4.1, from the NXP family.

How big is the MCL6809 PCB?

The MCL6809 measures 32.3 × 61 mm, has 4 copper layers and is 4.69 mm thick.

How many components are on the MCL6809?

7 components, from 3 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 MCL6809 design files?

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

Can I use the MCL6809 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 MCL6809 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.
