Lightsensor: common questions

What microcontroller does the Lightsensor use?

The Lightsensor is built around the ATmega328PB-A, from the AVR/Arduino family.

How big is the Lightsensor PCB?

The Lightsensor measures 128 × 128 mm, has 2 copper layers and is 1 mm thick.

How many components are on the Lightsensor?

115 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the Lightsensor design files?

From the marc-cr1810/SoccBot repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Lightsensor design in my own project?

The repository has no license, so all rights stay with marc-cr1810. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Lightsensor 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.
