Open Hardware Microfluidics Controller Arduino Shield

Finally, I managed to produce our first open hardware project.  The Microfluidics Controller allows us to drive 8 air pressure controllers and 8 air valves.  For this we have two 4-channel Digital-to-Analog chips (MCP4728) that produce voltages from 0-5V as input for our air-pressure controllers.  The air switching valves are driven using a darlington array […]
