An attempt at controlling a bunch of peristaltic pumps
I have ordered 8 Peristaltic Pumps. 12VDC 200-300mA https://www.adafruit.com/products/1150
I hope to drive them via a Raspberry Pi Model B and a Spark core. I want to be able to control the pumps individually with Mosfets for ON/OFF operation (Possibly via PWM) from the GPIO pins on the Raspberry Pi. I hope to connect the pumps via RJ45 connectors for easy connect and disconnect. I want to drive the entire system from a single 12V power supply. My current plan is to build my own PCB (first time ever so I need a little help) using these components and ordering the PCB from OSHPark.
Components for the build:
1 pcs Raspberry Pi Model B
1 pcs Spark Core http://spark.io
8 pcs Peristaltic Pumps. 12VDC 200-300mA (https://www.adafruit.com/products/1150)
8 pcs RJ45 8-Pin connectors (https://www.sparkfun.com/products/643)
8 pcs N-Channel MOSFET 60V 30A FQP30N06L (https://www.sparkfun.com/products/10213)
8 pcs 10k Ohm 1/4th W Resistors (https://www.sparkfun.com/products/8374)
8 pcs 1N4007 Diode MIC DO-41 1A 1000V Rectifier Diode
1 pcs Voltage Regulator - 5V L7805 (https://www.sparkfun.com/products/107)
1 pcs Raspberry Pi - GPIO Shrouded Header (2x13)
