1 Channel Relay Module DC 5V 10A Low/High Trigger for Arduino features:
- Channel: 1 (protected with Optocoupler)
- Supply voltage: 5V
- Output Current: 10A
- Relay activation current: 15mA ~ 20mA
- Insulation: Yes
- Trigger signal type jumper (low / high)
- LED indicator
- Dimensions: 30x 54mm
- Has a jumper that allows to choose type of trigger signal (low / high)
- This module can be controlled directly by the microcontroller (Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL)

Driver DRV8833 can control up to two DC motors or one stepper motor with a constant current of 1.5 A (peak 4A ). The motors are controlled, independently by means of PWM signals the direction of rotation of the motors can be controlled, neutral or stop with a frequency of up to 100 kHz. Two input signals (IN1 and IN2) can be used to control one motor (connected to OUT1 and OUT2) and the other two input signals (IN3 and IN4) to control the second motor (connected to OUT3 and OUT4). NOTE: This DRV8833 dual-bridge motor controller is the replacement for the TB6612FNG dual-channel motor controller. The pins come unsoldered. If the motor draws currents above 0.6A, the use of a heat sink may be required. DRV8833 Controller DC Motor PAP features:
