README
README.mdbedberry
PCB for intelligent electric bed/chair control. A board to allow those with disabilities a number of ways to control electric beds, chairs etc.
Based around the Raspberry Pi Zero 2W it is designed to allow abilities such as:
- Voice service (e.g. Alexa) control of the bed.
- Control of all the bed's function from simple buttons or pressure pads.
- Link to BLE tilt sensors to allow bed position 'presets'.
- Control of other devices via bluetooth, IR or WiFi, including TVs, lights, SwitchBots etc.

Questions
How big is the Bedberry PCB?
It measures 100 × 100 mm and has 4 copper layers, 1.59 mm thick.
What parts does the Bedberry use?
88 parts, built around the CPC1017N, CAT24C128LI-, MCP23017-E/SO and M2.5. 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 Bedberry KiCad files?
From the DarwinInnovation/bedberry repository on GitHub, at the commit this page was made from: the board is kicad/bedberry.kicad_pcb and its schematic kicad/IO_Bed.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bedberry design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
