Plantpal: common questions
What microcontroller does the Plantpal use?
The Plantpal is built around the ESP32-C6FH4, from the ESP32 family.
How big is the Plantpal PCB?
The Plantpal measures 38.4 × 128.5 mm, has 4 copper layers and is 1.58 mm thick.
How many components are on the Plantpal?
110 components, from 52 distinct parts. The full bill of materials is listed on this page.
Where can I download the Plantpal design files?
From the rajeev2705/PROJECTS repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Plantpal design in my own project?
The repository has no license, so all rights stay with rajeev2705. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Plantpal 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.
