L293D Driver Module Motor Driver Shield Motor Drive Expansion Board for Arduino Welcome to my store!! Descriptions: 2 interfaces for 5V Servo connected to For Arduino's high-resolution dedicated timer - no jitter! Can drive 4 DC motors or 2 stepper motors or 2 Servo Up to 4 bi-directional DC motors with individual 8-bit speed selection Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil or interleaved stepping. 4 H-Bridges: per bridge provides 0.6A (1.2A peak current) with thermal protection, can run motors on 4.5V to 36V DC Pull down resistors keep motors disabled during power-up Reset button 2 external terminal power interfaces, for separate logic/motor supplies Tested compatible for Arduino Mega, Diecimila & Duemilanove. The L293D V1 Motor Driver Shield has 4 full-bridge motor driver channels and can drive up to 4 DC motors or 2 stepper motors. It fits Arduino Uno or other Arduino with compatible I/O pins. KEY FEATURES OF L293D V1 MOTOR SHIELD: Drive 4 DC motors with speed and direction control Drive 2 stepper motors 4.5 – 25V motor voltage range 1.2A peak current per channel (600mA continuous) The L293D V1 Motor Shield can drive up to 4 DC motors at voltages from 4.5 – 25V and at currents of up to 1.2A peak (600mA continuous) per motor with speed and direction control. The module can also support up to 2 stepper motors. Each stepper motor takes the place of 2 of the DC motors, so you can run 2 stepper motors or 1 stepper motor and 2 DC motors or 4 DC motors. The shield also technically supports 2 servo motors for which there are two 3-pin headers on the module. Unfortunately, it powers the servo motors directly off the Arduino 5V which is never a good idea. Doing so can overheat the Arduino on-board 5V regulator as well as induce electrical noise into the Arduino 5V power causing intermittent problems that are difficult to troubleshoot, therefore it is not recommended to use this feature. If you are a hacker, the traces to the 5V center pins on the servo headers can be easily cut and rewired to a separate 5V power source. Motor Power Connections Motor voltage must be between 4.5 – 25V. This power can be shared with the Arduino or be separate. To select this, there is a jumper near the 2-terminal power connector labeled PWR. When this jumper is installed, the power from the Arduino DC power jack is also connected to the motors. Vin (marked 9V on the board) is brought up from the Arduino to power the motors. When the jumper is removed, that isolates the motor power from the Arduino and it must be supplied separately by connecting power to the 2-terminal power connector. Note: Do not apply power to the 2-terminal power connector with the jumper in place or it will short the two power supplies together! 1 x 2 Terminal EXT_PWR (Motor Power) +M = Motor Vcc which must be between 4.5 and 25V. GND = Motor Ground. DC Motor Connections The motor connections are via two screw terminals for each motor and labeled M1 thru M4. The center terminal on the 5-pos terminal blocks is connected to ground. The wiring of which lead of the motor connects to which terminal is somewhat arbitrary and relative to what you consider forward vs reverse motor operation. If the motor goes in the opposite direction that you expect, simply reverse the wiring. 1 x 2 Terminal M1 – M4 (DC Motor 1-4) Motor ‘- ‘positive lead Motor ‘+’ negative lead Stepper Motor Connections Stepper motors are typically 4 wires. Coil 1 will connect across one motor port such as M1 (M3) and coil 2 will connect across the other motor port such as M2 (M4). If the stepper motor has 5 wires, the center tap wire will be connected to the center ground terminal. 1 x 2 Terminal M1(M3) – M2(M4) (Servo Motor 1-2) Motor Coil 1 Motor Coil 2 Arduino to Shield Pin Connections The shield has a remote reset button located on it for easy access. The shield uses Pins D3, D4, D5, D6, D7, D8, D11 and D12 for DC and stepper motor control. D9 and D10 come out to the Servo headers. The other pins are available including the 6 analog pins that can also be used as digital I/O. These have solder pads so that a header can be added if desired for easy connections. Next to that is a row of 5V and Ground connections that can also be populated with headers if desired. OUR EVALUATION RESULTS: This is an older style motor driver which is very inexpensive and gets the job done for driving smaller DC motors or stepper motors. The chips are socketed for easy replacement should that be required. If you need a little more power handling and you are handy with soldering, it is possible to solder spare L293D chips piggy-back over the ones on the board. This effectively doubles the power handling capability to 2.4A peak and 1.2A continues current per motor. Using the module requires use of the Adafruit Motor Shield V1 (AFMotor.h) library that come with the Arduino IDE Notes: Due to manual measurement, there is a tolerance in the product size. Due to the lighting effects and shooting angles, there is color difference in the product, please understand.
