Pololu A4990 Dual Motor Driver Carrier hub-labor Linearizing the output:Allegro? s A4990 is a dual H bridge motor driver IC that can be used for bidirectional control of two brushed DC motors at 6 to 32 V. It can supply up to 0. 7 A continuously to each motor channel, and the current control feature of the A4990 limits the peak motor current to about 0. 9 A per channel with the onboard sense resistors, making this a good choice for small, low current motors that run on relatively high voltages. Since this board is a
