Servo Tester (3CH 4.8-6V)

12V DC Solenoid Water Air Valve Switch (Normally Closed) – 1/2″ controls the flow of fluid (liquid or air) and acts as a valve between high-pressure fluid! This liquid valve would make a great addition to your robotic gardening project. There are two ½” (Nominal NPT) outlets. Normally, the valve is closed. When a 12V DC supply is applied to the two terminals, the valve opens and water can push through.

The valve works with the solenoid coil which operates electronically with DC 12 volt supply. As it is a normally closed assembly, it opens the flow of fluids as soon as it is powered ON and stops/blocks the flow when the supply voltage removed.

Note:  While Connecting Valve in Flow pipeline, you need to mind the Input and Output direction of the valve. It will work only if you connect it in the right direction. (Hint: Inside the value, at one side you will find the filter this is the input side of the value)

Features:

1. Compact and convenient.
2. Easily installed and serviced
3. Precise and reliable.
4. The installation direction can be arbitrary Angle
5. Pressure-regulating valve (steady flow valve) function similar to the water flow switch
6. Not only can it provide a steady flow, but it also prevents the dry burning.
7. Suitable for fluids like water, oil, air.

Package Includes:

1 x 12V Solenoid Water Air Valve Switch (Normally Closed) – 1/2″

If you are new in multirotor/drone hobby area and want to try out some basic multirotor designs so as to enhance your basic knowledge about multirotors!!! Don’t wait and get this combo of  720 Magnetic Micro Coreless Motor + 55 MM Propeller for Micro Quadcopters (Set of 2Pcs).

Most importantly this 720 Magnetic Micro Coreless Motor is very compact and lightweight DC motor nicely crafted for perfectly matching with your small 100mm like multirotor frames.

They are 48000 RPM Motors which is more than needed to lift and push your drone to the target. These are less noisy with low resistance. The only drawback of using coreless is the amount of torque they provide, just because they are High Speed and Low Torque motors.

In this pack, we have included high-quality black 55mm propeller compatible with 720, 8520, 615 Coreless Motor.

The propellers are made of high-tenacity material and thus can sustain crashes. Therefore, this propeller with 720 Coreless motors is a perfect combination for your multirotor. Only, Plug-n-Play.

Features :

1. 720 Coreless motor is High Speed and Low Torque motor.
2. Less noisy operation.
3. Offers low resistance.
4. They are equipped with high-quality magnets.
5. This coreless motor supports 1S battery.

Package Includes :

2 x 720 Magnetic Micro Coreless Motor

2 x 55 mm Propeller (Color: Black)

This Flat 1034 Mobile Phone Vibrator Motor is a shaftless vibration motor that is fully-enclosed with no exposed moving parts. Its small size (10 mm diameter, 3.4 mm height) and shaftless design mean you can mount it on a PCB or even place it in a pocket to add quiet, haptic feedback to your project.

The motor has a 3M adhesive backing on it for easy mounting and 1.5″ leads for making quick connections. Polarity is not important; the motor can run CW or CCW.

This tiny, button-type, vibrating motor shakes with a vibration amplitude of 0.75g and draws approximately 60 mA when 3 V is applied to its leads.

Package Includes :

1 x Flat 1034 Mobile Phone Vibrator Motor.

The DRV8825 Stepper Motor Driver with Aluminum Heat Sink is a breakout board for TI’s DRV8825 microstepping bipolar stepper motor driver.

The module has a pinout and interface that are nearly identical to those of the A4988 stepper motor driver carriers, so it can be used as a higher-performance drop-in replacement for those boards in many applications.

The DRV8825 features adjustable current limiting, overcurrent, and overtemperature protection, and six microstep resolutions (down to 1/32-step). It operates from 8.2 – 45 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (rated for up to 2.2 A per coil with sufficient additional cooling).

Note: We are supplying two DRV8825 Drivers as DRV8825 Stepper Motor Driver with Aluminum Heat Sink- Good Quality and DRV8825 Stepper Motor Driver with Aluminum Heat Sink- Normal Quality. The difference between them is, the good quality DRV8825 has more number of PCB layers and it features the connecting pins which are of gold plated as compared to other. (refer to above image)

Using the Driver

Features :

1. Microstep resolutions: full, 1/2, 1/4, 1/8, 1/16, and 1/32.
2. Simple step and direction control interface
3. Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step
4. Adjustable current control lets you set the maximum current output with a potentiometer. Hence lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates
5. Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
6. 45 V maximum supply voltage
7. Built-in regulator (no external logic voltage supply needed)
8. Can interface directly with 3.3 V and 5 V systems
9. Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout
10. Short-to-ground and shorted-load protection
11. 4-layer, 2 oz copper PCB for improved heat dissipation
12. Exposed solderable ground pad below the driver IC on the bottom of the PCB

Package Includes :

1 x DRV8825 Stepper Motor Driver with Aluminum Heat Sink- Good Quality.
