Pumps: common questions
What microcontroller does the Pumps use?
The Pumps is built around the Pico H, from the RP2040/RP2350 family.
How big is the Pumps PCB?
The Pumps measures 330 × 225.9 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Pumps?
86 components, from 42 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 Pumps design files?
From the DagaVedant/Hydroponic-Garden 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 Pumps design in my own project?
The repository has no license, so all rights stay with DagaVedant. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Pumps without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
