About the Valve control PCB

Valve control is an open source AVR/Arduino PCB design by GNHua, published on GitHub under the MIT license. It is a 2-layer board measuring 73.7 × 55.9 mm, with 48 components from 11 distinct parts.

Its main chip is the Arduino_Uno_Shield, from the AVR/Arduino family. Other key parts include the 74HC595 and HCPL2731. By type, the board carries 16 resistors, 13 connectors, 8 transistors, 5 ICs, 4 diodes and 1 capacitor.

Use Arduino Uno to control solenoid valves

Use Arduino Uno to control solenoid valves. Follow the steps below to set up your own valve control station.

Clippard, E310C-2C012, 10 mm N-C 3-way Valve, In-line Connector w/LED, 0.030" Orifice, 1.3W, 12 VDC Valve connector cable * Manifold

Details can be found on page 215-221 in Clippard Full-line Catalog

Highly recommend JLCPCB. Fabrication and shipping took ~1 week for me in the U.S. If you choose JLCPCB, go here, upload plots.zip, and leave everything else as default. * If you have access to a PCB baking oven, buying a SMT-Stencil will save you a lot of time for soldering. If not, all…

Valve control: common questions

What microcontroller does the Valve control use?

The Valve control is built around the Arduino_Uno_Shield, from the AVR/Arduino family.

How big is the Valve control PCB?

The Valve control measures 73.7 × 55.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Valve control?

48 components, from 11 distinct parts. The full bill of materials is listed on this page.

Where can I download the Valve control design files?

From the GNHua/valve-control repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Valve control design in my own project?

Yes, under the terms of its MIT license, which GNHua chose for the repository.

Can I test firmware for the Valve control without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
