Hw openmower yardforce: common questions
What microcontroller does the Hw openmower yardforce use?
The Hw openmower yardforce is built around the Ardusimple_F9P, from the AVR/Arduino family.
How big is the Hw openmower yardforce PCB?
The Hw openmower yardforce measures 180 × 170 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Hw openmower yardforce?
275 components, from 104 distinct parts. The full bill of materials is listed on this page.
Where can I download the Hw openmower yardforce design files?
From the xtech/hw-openmower-yardforce repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Hw openmower yardforce design in my own project?
Yes, under the terms of its CC-BY-4.0 license, which xtech chose for the repository.
Can I test firmware for the Hw openmower yardforce 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.
