Control DC motors, Servos, and Stepper motors!
This is a pack of DC MOTOR CONTROL modules:
- Transistor DC Switch module, 5V logic, DC 24V/30A
- Motor Shield L293D 4-DC/2-Stepper motors for Arduino (assembled)
- Stepper Motor Driver A4988 module for 3D printers, with heat sink
Transistor DC Switch module, 5V logic, DC 24V/30A
If you need to control the DC power, a MOSFET is what you need. This is a very common MOSFET with very low on-resistance and a control voltage (gate threshold voltage) that is compatible with any 5V microcontroller or mechanical switch. This allows you to control high-power devices with very low-power control mechanisms.
This board has an Opto-isolator to protect your microcontroller from high currents.
More space is still available just in case you need to install a heat sink for the MOSFET.
Technical characteristics :
- Output DC Voltage: 4.5V-24V (peak 36V) 50W
- Transistor: N-chanel MOSFET
- Control Voltage: 5V
Motor Shield L293D 4-DC/2-Stepper motors for Arduino (assembled)
The L293D Motor Shield for Arduino is a great and quick way to control DC motors, servos or even stepper motors. It has the capability of controlling up to 2 stepper motors, 4 DC motors. and 2 servos. This shield is a very good start for beginners because of its versatility for its price range.
– Four H-Bridges: Two L293D Motor driver chips
– L293D is rated at 0.6A per bridge (1.2A peak) with thermal shutdown protection, internal kickback protection diodes.
– Motor Voltages from 4.5VDC to 16VDC. (up to 36V if C6 and C7 are upgraded)
– Up to 4 bi-directional DC motors with individual 8-bit speed selection (256 speeds)
– Up to 2 stepper motors (unipolar or bipolar)
– Pull down resistors keep motors disabled during power-up
– Separate Logic and Motor power connections
– Terminal block connectors for motors and power
– 2 connections for 5V ‘hobby’ servos
Stepper Motor Driver A4988 module for 3D printers, with heat sink
A4988 module is a complete microstepping motor driver with built-in translator for easy operation. This driver can be used in full, half, 1/4, 1/8 and 1/16 step modes to operate bipolar stepper motors. Output drive capacity is up to 35 V and ± 2A. The A4988 module includes a fixed off-time current regulator which can be used in slow or mixed decay modes.
The A4988 converter is the key to the easy implementation. Every “step” input from one pulse drives the motor one microstep. There are no phase sequence tables, high frequency control lines, or complex interfaces to program.
The A4988 interface is very suitable when complex microprocessor is unavailable or is overburdened. During micro-step operation, the A4988 chopping control automatically selects the current decay mode (Slow or Mixed). In mixed decay mode, the device is initially set to a fixed downtime at fast decay, then the rest of the operation is in the slow decay downtime. Mixed decay current control scheme results in reduced audible motor noise, increased step accuracy, and reduced power consumption. Internal synchronous rectification control circuitry is provided to improve the pulse-width modulation (PWM) operation, thus reducing power consumption. Internal circuit protection includes: thermal shutdown with hysteresis, undervoltage lockout (UVLO), and crossover-current protection. Special power sequencing is also included.
