Lidar: common questions

What microcontroller does the Lidar use?

The Lidar is built around the ATmega128A, from the AVR/Arduino family.

How big is the Lidar PCB?

The Lidar measures 40 × 37 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Lidar?

35 components, from 22 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 Lidar design files?

From the le-flav-b/VEMAR 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 Lidar design in my own project?

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

Can I test firmware for the Lidar 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.
