Esp32s3-plant monitor: common questions

What microcontroller does the Esp32s3-plant monitor use?

The Esp32s3-plant monitor is built around the ESP32-S3-WROOM-1-N8, from the ESP32 family.

How big is the Esp32s3-plant monitor PCB?

The Esp32s3-plant monitor measures 62.5 × 44.5 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the Esp32s3-plant monitor?

51 components, from 28 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 Esp32s3-plant monitor design files?

From the MuffinByteLabs/esp32s3-plant-monitor 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 Esp32s3-plant monitor design in my own project?

Yes, under the terms of its CERN-OHL-P-2.0 license, which MuffinByteLabs chose for the repository.

Can I test firmware for the Esp32s3-plant monitor 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.
