This motor driver shield can drive up to 4 DC motor with 2 servo motors or 2 stepper motors with 2 servo motors. This motor driver shield uses a 2x L293D motor controller chip with a 74HC595 shift register for all of its functions.
It has 2 connections for 5v servos connected to the arduino’s high-resolution dedicated timer.
It’s 4 h-bridges and l293d chipset provide 0. 6A per bridge.
It comes with thermal shutdown protection and internal kickback protection diodes.
It can run motors on 4. 5vdc to 25vdc.
It provides up to 4 bi-directional dc motors with individual 8-bit speed selection with single coil, double coil or interleaved stepping.
The pull-down resistors keeps motors disabled during power-up.
It has big terminal block connectors to easily hook up wires and power arduino reset button brought up top 2-pin terminal block and jumper to connect external power, for separate logic/motor supplies.
This shield is driven by 2 L293D chips, which are very strong 4-channel drivers. Because of the power of these chips, this shield can control 4 DC motors or 2 stepper / servo motors. This board can control four channels with 0.6A (1.2A peak) with heat protection and can supply a voltage of 4.5V to 36V DC (external power supply possible).
