PCB Watersysteem: common questions
What microcontroller does the PCB Watersysteem use?
The PCB Watersysteem is built around the AMS1117-3.3, from the ESP32 family.
How big is the PCB Watersysteem?
The PCB Watersysteem measures 89.3 × 100 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the PCB Watersysteem?
88 components, from 56 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 PCB Watersysteem design files?
From the Vertical-Farming-IB3/Plan-T 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 PCB Watersysteem design in my own project?
The repository has no license, so all rights stay with Vertical-Farming-IB3. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the PCB Watersysteem 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.
