2 DC Motor / 1 Stepper Motor Driver Shield – 10 A

Description

Arduino shield based on an H-bridge made of 8 NMOS transistors, which besides providing better efficiency, eliminates the need for a heat sink. Designed for 2 DC motors with a supply voltage from 7 VDC to 30 VDC and a maximum current of 10 A. Compatible with Arduino UNO, Arduino Mega, Maker Uno, Maker Uno Plus, or Arduino-compatible boards. It features a screw terminal for motor connection, test buttons, external control inputs, status LEDs, jumpers for PWM and DIR pin selection, a reset button, and male/female pin strips that allow stacking other boards. Dimensions (mm): 82.80 x 59 x 21.

Warning! The power input has no reverse polarity protection. Connecting the battery with reversed polarity will instantly damage the motor driver.
