Overview
Hw openmower universal is an open-source printed circuit board by xtech, from the xtech/hw-openmower-universal repository on GitHub, published under the CC-BY-4.0 licence. It is a 4-layer board of 220 × 172.8 mm with 472 parts on 344 nets, routed with 2,241 tracks and 928 vias.
It is built around the 22PF/50V 10%, VS-2EFH02HM3/I and BSC0702LS, with the SS14, AO3400A and HR911130A among its other parts. Its parts include 116 capacitors, 82 resistors, 64 ICs, 46 connectors and 34 diodes.

README
README.mdUniversal OpenMower Mainboard
[!WARNING]
⚠️ This repository is deprecated
The universal board has been split into multiple smaller modules. Reasons:
- some people had issues breaking the board
- people can order replacements without needing to order the whole board
- iteration on individual modules is easier
- hardly anyone used the board in a non-broken fashion anyways, since it was too large for most mowers
Please use the following repos instead:
- hw-module-xesc — carrier to use xESC standalone
- hw-module-charger — charger module
- hw-module-logic — logic board for universal application
- hw-module-gps — module for using Arduino Shield style GPS units with xBot modular platform
Information
This hardware version is in beta state. Expect for things to not work at the current state!
If you want to build an OpenMower, I recommend the tested v1 hardware.
About This Repo
OpenMower is an open-source project that upgrades off-the-shelf robotic mowers into modern, smart lawn mowing robots with RTK GPS technology. For more details, check out the OpenMower project.
This repository contains the design files for a custom mainboard specifically designed for converting YardForce mowers to OpenMower.
List of Compatible Mowers
This mainboard is compatible with the following mower models: TBD

Questions
How big is the Hw openmower universal PCB?
It measures 220 × 172.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Hw openmower universal use?
472 parts, built around the 22PF/50V 10%, VS-2EFH02HM3/I, BSC0702LS and SS14. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Hw openmower universal KiCad files?
From the xtech/hw-openmower-universal repository on GitHub, at the commit this page was made from: the board is hw-openmower-universal.kicad_pcb and its schematic Amplifier.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hw openmower universal design in my own project?
Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
