ML Sensor: common questions

What microcontroller does the ML Sensor use?

The ML Sensor is built around the Arduino_Mega2560_Shield, from the AVR/Arduino family.

How big is the ML Sensor PCB?

The ML Sensor measures 101.6 × 53.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ML Sensor?

23 components, from 9 distinct parts. The full bill of materials is listed on this page.

Where can I download the ML Sensor design files?

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

Can I use the ML Sensor design in my own project?

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

Can I test firmware for the ML Sensor 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.
