Motor shield V2.0 TB6612 et PCA9685 (Motor-shield-v2-TB6612)
- Fully compatible with interface extensions.
- Address can be modified through I2C and communication.
- It can connect 2 steering gear and output PWM drive directly.
- Up to 4 bi-directional DC motors
- Up to 2 stepper motors (unipolar or bipolar)
- 4 H-Bridges: TB6612 chipset provides 1.2A per bridge (3A for brief 20ms peaks) with thermal shutdown protection, internal kickback protection diodes. Can run motors on 4.5VDC to 13.5VDC
- 2 connections for 5V 'hobby' servos connected to the Arduino's high-resolution dedicated timer - no jitter!
- Big terminal block connectors to easily hook up wires (18-26AWG) and power
- Tested compatible with Arduino UNO, Leonardo, ADK/Mega R3, Diecimila & Duemilanove. Works with Due with 3.3v logic jumper. Works with Mega/ADK R2 and earlier with 2 wire jumpers
A4988 Stepper Motor Driver
- This product is a breakout board for Allegro's A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection;
- This stepper motor driver lets you to operate bipolar stepper motors in full-, half-, quarter-, eighth-,
and sixteenth-step modes, with an output drive capacity of up to 35 V and 2 A. - The translator is the key to the easy implementation of the A4988.
- Simply inputting one pulse on the STEP input drives the motor one microstep.
- There are no phase sequence tables, high frequency control lines, or complex interfaces to program.
- The A4988 interface is an ideal fit for applications where a complex microprocessor is unavailable or is overburdened.
- Features
- Simple step and direction control interface
- Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step
- Adjustable current control lets you set the maximum current output with a potentiometer,
which lets you use voltages above your stepper motor's rated voltage to achieve higher step rates - Intelligent chopping control that automatically selects the correct current decay mode
(fast decay or slow decay) - Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection
- Short-to-ground and shorted-load protection
