I have purchased x2 252cfm DC 3 wire fans to build my wind sim but not sure if I’ve ordered the correct Arduino and motor shield. The fans are 12v 48w 5000rpm fans will the Arduino rev 3 power two of them? I’ve followed the boosted diy windsim video but only thing different is I’ve got higher cfm fans, first ever go at something like this and I’m in no way an electrician so pls be kind lol

The Adafruit motor shield kit for Arduino gives you the ability to drive up to 4 DC motors or 2 stepper motors and can be stacked to add more motors, leaving the pins on the Arduino free for more inputs and outputs for sensors. The TB6612 MOSFET drivers have been used in place of the previously used L293D darlington driver, with 1.2A per channel current capability (you can draw up to 3A peak for approx 20ms at a time). It also has much lower voltage drops across the motor so you get more torque out of your batteries, and there are built-in flyback diodes as well. There is a fully-dedicated PWM driver chip onboard. This chip handles all the motor and speed controls over I2C. Only two pins (SDA & SCL) are required to drive the multiple motors, and since it's I2C you can also connect any other I2C devices or shields to the same pins. This also makes it drop-in compatible with any Arduino, such as the Uno, Due, Leonardo and Mega R3. Completely stackable des
thanks in advance

Hi !
If I'm not wrong 48w at 12v is 4 amps, you would be above of the motorshield V2 specifications, for such fans you will need to opt for the monster moto Shield https://github.com/SHWotever/SimHub/wiki/Arduino-Shake-It#monster-moto-shield

Thankyou for the reply and the advice Nicolas. Much appreciated.. I’ll send the one I’ve ordered back and switch the this one.. all the best and thanks again

Is it this one I need?
Monster Moto Shield VNH2SP30 stepper motor driver module high current 30A replace by VNH3SP30 £4.98
or there is another one that looks the same but for £50.00. Does say discontinued product though?

Hi I’ve ordered this one which I believe is the right one. Again thank you

Do you have more information (a link) on the FAN you are using?
Did you manage to get both fans spooling?
