IRF520 MOSFET Driver Module is a breakout board for the IFR520 MOSFET transistor. The module is designed to switch heavy DC loads from a single digital pin of your microcontroller.

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

Its main purpose of this IRF520 MOSFET Driver Module is to provide a low-cost way to drive a DC motor for robotics applications, but the module can be used to control most high current DC loads. Screw terminals are provided to interface with your load an external power source. An LED indicator provides a visual indication of when your load is being switched.

The simplest way of explaining how this little board works is as below,

You connect the power for the device you want to control 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.

Pin Connections :Features :

1. Using original IRF520 Power MOS, you can adjust the output PWM
2. Arduino drive up to 24V allows the load, such as LED lights, DC motors, miniature pumps, solenoid valves

This is 0.28-inch Digital Voltmeter Ammeter DC 100V 50A LED Amp Volt Meter With Shunt. This meter will measure up to 100 VDC with a 0.1-volt resolution.

One thing to note is, this meter has 2 wiring harnesses. One harness is to provide power for the meters, that’s the 2 poles with a RED and a BLACK lead. Small size, portable, the magnitudes of voltage and current are displayed on the same screen at the same time.

This can be supplied anywhere from 6 volts DC up to 30 VDC. This is a separate power supply that is isolated from the source, it is possible to use the same supply but it seems to affect the amp meter reading. The 3 wire harness is used for a ground that connects directly to the battery or supply ground of the load.

Note: There are two different wiring variants (i.e. yellow wire and Green wire ) with the same working functionality is available which will be shipped randomly. Use the followings guidelines according to your version.

CASE 1: Onboard Wiring Instructions for “Yellow” Wire connection

1. Thin Red Wire (VCC): positive pole of power supply input (4.5-30V)
(Note: if the measuring signal is less than 30V and the power is adequate, can be the power supply of module)

2. Thin Black Wire (GND): the negative pole of power supply input (4.5-30V, common ground with measuring signal)

3. Green Wire (VIN): positive pole of measuring signal input (0-100V)

4. Thick Red Wire (I+): positive pole of current input (series connect on the power supply cathode)

5. Thick Black Wire (I-): the negative pole of current input (series connect on the power supply cathode)

Connection Diagram:

 

Note: If the input voltage is more than 5V then please use the buck converter.

CASE 2: Onboard Wiring Instructions for “Green” Wire connection

(The current range of 10A requires the external shunt connection process)

1. Connect the lines which are not connected well, and do not touch other places.

2. The shunt is connected to the negative pole of the measuring system (the shunt itself does not distinguish the direction, and the connection is fixed to the two large screw holes in the distributor.

3. According to the current direction, the green line (+) and the black line (-) of the three lines are respectively screwed on the two small screws of the shunt.

4. Connect the red line of the three lines to the positive pole of the measuring system.

5. The power supply line in the two lines is connected to the appropriate power supply (and the voltage between the black lines in the three lines. It is suggested to be connected to the 12V, at the same time, the electric power black lines in the two lines are wrapped with insulating tape, so do not encounter other places, so as not to cause a short circuit).

6. The above 1-5 steps are suitable for the use of common ground; for independent power supply occasions, the red and black lines of power supply in two lines are respectively connected to both sides of the positive and negative poles of the power supply (the power supply voltage <28V, suggested to be about 12V).

QUICK OVERVIEW

1. Material: Aluminium.
2. Bore Diameter d1: 5 MM.
3. Bore Diameter d2: 8 MM.
4. Torsional stiffness: Zero backlash
5. One piece construction

This flexible type motor coupling can connect your driving shaft with the driven shaft while it is very efficient in eliminating any misalignment to the possible extent. Minimum backlash is another great advantage of this Aluminium Flexible Coupling Coupler Helical Shaft 5mm x 8mm.

This Flexible coupling with the outer diameter of 19mm and the length of 25mm is machined aluminum coupling.

First bore diameter is 5mm and the second bore diameter is of 8mm also.

It comes with the spiral cut in the middle along its length which makes it flexible so they can be fit to two shafts even if they are not perfectly co-linear and will help reduce binding effects. Such couplings are also known as Beam coupling, helical coupling, Flexible coupling.

Some of the important features of flexible shaft coupling are,

1. Helical cut makes them behave like a springy in the X Y and Z linear axis but not in the rotational axis. That means that you won’t get more backlash, hence they are suitable for precision CNC work.
2. A coupling is a device which transmits power and torque. Couplings do not normally allow disconnection of shafts during operation. However, there are torque limiting couplings which can slip or disconnect when some torque limit exceeds.
3. By careful selection, installation and maintenance of couplings, substantial savings are possible in reduced maintenance costs and downtime.
4. It can protect the driving and driven shaft members against harmful effects because of misalignment of the shafts, sudden shock loads, shaft expansion or vibrations etc.

This is DC To AC SSR-40DA Solid State Relay Module 3-32VDC/24-380VAC 40A. A solid state relay (SSR) allows you to control high-current AC loads from lower voltage DC control circuitry. Solid state relays have several advantages over mechanical relays.

One such advantage is that they can be switched by a much lower voltage and at a much lower current than most mechanical relays. Also, because there are no moving contacts, solid state relays can be switched much faster and for much longer periods without wearing out.

This particular SSR can switch current loads of up to 40A with a 3-32V DC input and a zero cross trigger control method. Each one of these relays is equipped with four screw terminals (for use with ring or fork connectors) and a plastic cover that slides over the top of the relay to protect the terminals.
