Phenobottle sensorboard: common questions

What microcontroller does the Phenobottle sensorboard use?

The Phenobottle sensorboard is built around the ESP32-S3, from the ESP32 family.

How big is the Phenobottle sensorboard PCB?

The Phenobottle sensorboard measures 84.4 × 68.2 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Phenobottle sensorboard?

148 components, from 51 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Phenobottle sensorboard design files?

From the Flynsky/phenobottle-sensorboard repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Phenobottle sensorboard design in my own project?

The repository has no license, so all rights stay with Flynsky. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Phenobottle sensorboard without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
