Plant monitor: common questions
What microcontroller does the Plant monitor use?
The Plant monitor is built around the STM32L071KBT6, from the STM32 family.
How big is the Plant monitor PCB?
The Plant monitor measures 50 × 74 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Plant monitor?
168 components, from 50 distinct parts. The full bill of materials is listed on this page.
Where can I download the Plant monitor design files?
From the PimentoFr/plant-monitor repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Plant monitor design in my own project?
The repository has no license, so all rights stay with PimentoFr. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Plant monitor without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
