Questions
How big is the Phenobottle sensorboard PCB?
It measures 84.4 × 68.2 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Phenobottle sensorboard use?
160 parts, built around the ESP32-S3, OPT3002DNPR, ADS1115IDGS and MIC5504-3.3YM5. 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 Phenobottle sensorboard KiCad files?
From the Flynsky/phenobottle-sensorboard repository on GitHub, at the commit this page was made from: the board is Hardware/Phenobottle Sensorboard PCB/Phenobottle Sensorboard.kicad_pcb and its schematic Hardware/Phenobottle Sensorboard PCB/Phenobottle Sensorboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Phenobottle sensorboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask Flynsky before reusing the design.
