LineSensor: common questions

What microcontroller does the LineSensor use?

The LineSensor is built around the ARDUINO_NANO_V2.X, from the AVR/Arduino family.

How big is the LineSensor PCB?

The LineSensor measures 389.4 × 319.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the LineSensor?

145 components, from 16 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 LineSensor design files?

From the Tellurnoid/25RoboCup 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 LineSensor design in my own project?

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

Can I test firmware for the LineSensor 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.
