Pololu Dual MC33926 Motor Driver Shield for Arduino POL_Female-Female Wires with Pre-Crimped Terminals The control lines can be

The control lines can be reduced to two pins if PWM signals are applied directly to the two input pins with both disable pins held inactive

This unit displays a digital readout of the actual air temperature with a flow rate of up to 24L per minute

The relays are SPCO (Single Pole Change Over) types

you'll be able to program the Arduino controller

It ships with the single battery contacts already soldered in

Pololu Dual MC33926 Motor Driver Shield for Arduino POL_Female-Female Wires with Pre-Crimped Terminals The control lines can beThis shield makes it easy to control two brushed DC motors with your Arduino or Arduino compatible board. Its dual MC33926 motor drivers operate from 5 to 28 V and can deliver a continuous 3 A per motor. These great drivers also offer current sense feedback and accept ultrasonic PWM frequencies for quieter operation. The Arduino pin mappings can all be customized if the defaults are not convenient, and the motor driver control lines are broken out
