HB-Mower-Fence: common questions

What microcontroller does the HB-Mower-Fence use?

The HB-Mower-Fence is built around the ATmega328PB-AU, from the AVR/Arduino family.

How big is the HB-Mower-Fence PCB?

The HB-Mower-Fence measures 69.9 × 46.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the HB-Mower-Fence?

30 components, from 24 distinct parts. The full bill of materials is listed on this page.

Where can I download the HB-Mower-Fence design files?

From the stan23/myPCBs repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the HB-Mower-Fence design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the HB-Mower-Fence 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.
