HydCircCon: common questions
What microcontroller does the HydCircCon use?
The HydCircCon is built around the RP2040, from the RP2040/RP2350 family.
How big is the HydCircCon PCB?
The HydCircCon measures 50 × 40 mm, has 4 copper layers and is 1.6062 mm thick.
How many components are on the HydCircCon?
111 components, from 49 distinct parts. The full bill of materials is listed on this page.
Where can I download the HydCircCon design files?
From the Bergi84/GrowOMatic repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the HydCircCon design in my own project?
The repository has no license, so all rights stay with Bergi84. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the HydCircCon 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.
