Muscle imbalance detection: common questions

What microcontroller does the Muscle imbalance detection use?

The Muscle imbalance detection is built around the ATmega328P-AU, from the AVR/Arduino family.

How big is the Muscle imbalance detection PCB?

The Muscle imbalance detection measures 56.8 × 68.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Muscle imbalance detection?

82 components, from 15 distinct parts. The full bill of materials is listed on this page.

Where can I download the Muscle imbalance detection design files?

From the leikoilja/muscle-imbalance-detection repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Muscle imbalance detection design in my own project?

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

Can I test firmware for the Muscle imbalance detection 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.
