Questions
How big is the Borneo doser mainboard PCB?
It measures 95 × 35 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Borneo doser mainboard use?
74 parts, built around the ESP32-WROOM-32, XL1509-3.3E1, DS1302Z+ and AO3400. 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 Borneo doser mainboard KiCad files?
From the oldrev/borneo-doser repository on GitHub, at the commit this page was made from: the board is hardware/borneo-doser-mainboard/borneo-doser-mainboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Borneo doser mainboard design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
