  • IRF520 MOS FET Driver Module ( Copy ) ()

    Description: RF520 Mosfet Driver Module

    Specifications:

    Here is a simple breakout board for the IRF520 Mosfet. Easy hookup to your Arduino or other 3-5v micro controller. Pulse current through a PWM pin, and use this to control a pump, LED, or other DC device at up to 24v, and ~5A. You can check the specs here.

    Real simple to use: The simplest way of explaining how this little board works is this: You connect the power for the device you want to control to the Vin and GND. You connect your device to the V+ and V- screw terminals. When the SIG line is HIGH, a little LED lights up, and the GND is 'connected' to the V-. When the SIG line is LOW, the LED turns off, and the GND becomes 'disconnected' to the V-. The V+ and Vin are continuously connected.

    You can power this device from your Arduino, VCC goes to the 5V connection, and GND to the GND pin on your Arduino.



    Features:
     

    • Voltage: 3.3V, 5V
    • Output load voltage :0-24V
    • Output load current: <5A (1A and above requires a heat sink)
    • Platform: Arduino, MCU, ARM, Raspberry PI.
    • Using original IRF520 Power MOS, you can adjust the output PWM.
    • Drive up to 24V allows the load, such as LED lights, DC motors, miniature pumps, solenoid valves.
    • PWM dimming LED can be used to achieve step less dimming, variable speed motor control.
    • Note: Above 1 A load, you need to install heat sink.

  • toradex oak IO module ()
    The Oak IO is a USB attached digital input / output board. Each of the 24 I/Os can be configured 
    individually to act as CMOS input, CMOS output or open drain I/O. The logic level of all I/Os can 
    be set to 3.3V or 5V by a single jumper. 
    8 of the 24 I/O lines are ESD protected and have disconnectable interfaces. The mating connectors 
    feature screw terminals to allow a quick attachment of bare wires. These I/O lines are provided 
    with pull up resistors to allow direct sensing of switches without external circuitry. 
    For the other 16 I/O lines, a pin header with a 2.54mm pitch is provided for a simple connection 
    of the inputs and outputs. 
    The output lines can be set with a maximum USB latency of 1ms. The report rate for reading the 
    I/O pins is user adjustable from 1ms to 65s. The minimum USB latency for reading the inputs is 
    therefore 1ms. 
    The Oak IO can be integrated in a custom application very easily. The operating power as well as 
    real time input/output data and uncritical device configuration data are all transferred through a 
    simple USB cable. The very low power consumption, including automatic entering into sleep mode, 
    allows using the device not only in fixed installation, but also in mobile applications.

  • toradex oak 10V module ()
    The Oak 10V is a USB attached analog to digital converter board with 8 single-ended channels or 
    4 pseudo-differential channels. The ADC board can run at a sampling rate of up to 1kHz 
    independent of the number of used channels. Voltages between -10V and +10V can be measured 
    with a resolution of approximately 5mV (12 bit ADC)
    The analog inputs are completely isolated from the USB circuit. There is no isolation between the 
    analog input channels because they have a common ground. To simplify installation, the analog 
    inputs feature disconnectable interfaces. The mating connectors have screw terminals to allow for a 
    quick attachment of bare wires. 
    The Oak 10V can be integrated in a custom application very easily. The operating power as well as

  • Arduino UNO R3 ( UNO R3)
    Microcontroller ATmega328
    Operating Voltage 5V
    Input Voltage (recommended) 7-12V
    Input Voltage (limits) 6-20V
    Digital I/O Pins 14 (of which 6 provide PWM output)
    Analog Input Pins 6
    DC Current per I/O Pin 40 mA
    DC Current for 3.3V Pin 50 mA
    Flash Memory 32 KB (ATmega328) of which 0.5 KB used by bootloader
    SRAM 2 KB (ATmega328)
    EEPROM 1 KB (ATmega328)
    Clock Speed 16 MHz
     

    The power pins are as follows:

    • VIN. The input voltage to the Arduino board when it's using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). You can supply voltage through this pin, or, if supplying voltage via the power jack, access it through this pin.
    • 5V.This pin outputs a regulated 5V from the regulator on the board. The board can be supplied with power either from the DC power jack (7 - 12V), the USB connector (5V), or the VIN pin of the board (7-12V). Supplying voltage via the 5V or 3.3V pins bypasses the regulator, and can damage your board. We don't advise it.
    • 3V3. A 3.3 volt supply generated by the on-board regulator. Maximum current draw is 50 mA.
    • GND. Ground pins.
    • IOREF. This pin on the Arduino board provides the voltage reference with which the microcontroller operates. A properly configured shield can read the IOREF pin voltage and select the appropriate power source or enable voltage translators on the outputs for working with the 5V or 3.3V.
