NLog 9DoF: common questions

What microcontroller does the NLog 9DoF use?

The NLog 9DoF is built around the ATMEGA644PA-A, from the AVR/Arduino family.

How big is the NLog 9DoF PCB?

The NLog 9DoF measures 45 × 45 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the NLog 9DoF?

51 components, from 28 distinct parts. The full bill of materials is listed on this page.

Where can I download the NLog 9DoF design files?

From the kentN/nLog_9DoF repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the NLog 9DoF design in my own project?

Yes, under the terms of its MIT license, which kentN chose for the repository.

Can I test firmware for the NLog 9DoF without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
