This 3V vertical submersible low power water pump is an ideal solution for creating a small indoor water feature or as part of a plant watering system. At the heart of the pump is a 3V DC motor that runs quietly and only draws approximately 100mA.

The pump needs priming before use and should be kept fully submerged during use as it will only pump water not air. Also, it only works in one direction as a pump, you cannot reverse the connections and have it move water in the other direction.

It's 3V, 100mA power requirements are such that you could use a microcontroller with suitable drive capacity to switch it on or off. As the new micro:bit now has 200mA available for powering external devices, this pump can be powered directly by the micro:bit V2.

The micro:bit can only drive 15mA from its pins, so a transistor or FET is required to control it from the pins, either in an on/off capacity, or, with PWM to vary pumping rate. If using the original micro:bit or if the microbit is already controlling other devices, this pump can also be powered and controlled via a motor driver board, or similar.

Note: This pump is not supplied with any tubing.

Features:

Vertical type submersible pump.

Operating power requirements are; 3V and 100mA.

Low noise DC motor.

Can be controlled with a simple on/off switch or microcontroller/motor driver board.

Ideal for small water features or plant watering systems.

Kitronik's new clippable servo has had the standard pin header replaced with super useful crocodile clips. This allows it to be used in projects that feature other clippable connection points, such as projects utilising the Kitronik Klip Motor Driver.

The 180 degree rotation servo is based on the Feetech FS90MG-CL and features metal gears, which are more reliable and hard-wearing than their plastic counterparts. The servo is rated to operate between 4.8V - 6V, which gives output Torque of between 1.8kg - 2.2kg respectively. If the clippable servo is being used in micro:bit projects, a separate power supply is required. If you are using the Kitronik Klip Motor Driver, the power can be taken directly from the Klip motor driver board.

The servo can rotate approx. 180 degrees, or approx. 90 in each direction, and it can be driven with any standard 180 degree servo code/libraries. It can be coded using the MakeCode or Python editors which makes it ideal for novice or expert level microbit projects.

The servos are supplied with four horns and the associated fixings which should allow you to slot these servos into your projects with relative ease and without the need to make custom horns.

Note: This servo requires a separate power supply from the controlling micro:bit. Attempting to power this servo directly from the micro:bit is likely to cause permanent damage to the micro:bit.

Features:

This FS90R Mini 360 Servo by Feetech is a great value multi-purpose micro size servo and it's ideal for use with micro-controller systems like the BBC microbit, Arduino, Raspberry Pi and PICAXE. It's miniature size also makes it great for use in radio controlled models and small robot projects.

This is a 360 degree continuous rotation servo. Its operation is very different to that of a standard servo. Instead of going to a specified angle, this servo will be static at a 1.5ms pulse (a trimmer is included to tweak this), a longer pulse gives forward rotation and a shorter pulse give backwards rotation.

The FS90R continuous rotation servo converts standard RC servo position pulses into continuous rotation speed. The default rest point is 1.5 ms, but this can be adjusted by using a small screwdriver to turn the middle-point adjustment potentiometer. Pulse widths above the rest point result in counterclockwise rotation, with speed increasing as the pulse width increases; pulse widths below the rest point result in clockwise rotation, with speed increasing as the pulse width decreases.

It comes with mounting screws and a range of horns to suit most applications. You can use any servo code, hardware or library to control these servos, so it's great for beginners who want to make things move without the need for a motor driver board. These servos are fully compatible with our Servo:Lite board which is also included in the :MOVE mini buggy kit for the BBC microbit.

This 90RPM in-line geared TT hobby motor is a great cost-effective solution for adding some movement to your buggy/robot builds. It can be used with our matching wheels and with our motor driver boards, such as our Motor Driver Board for Raspberry Pi Pico and the Compact Motor Driver Board for the BBC micro:bit, to name just two. Note: when using a microcontroller, do not drive these motors directly with the microcontroller, always use them in conjunction with a motor driver board.

Despite their low price point, these brightly coloured 120:1 motors are quite durable and are likely to last through multiple builds with ease.

Although there is a gearbox between the motor and the shaft, there are no rotary encoders. When connected to an appropriate motor driver, like the two listed above, you get forwards/backwards/stop. Simple yet effective. With 2 motors connected to a motor driver, you can also have directional control by turning off one motor and not the other. As is sometimes the case with servos and motors, there can be some small RPM differences between motors which can be overcome when coding, a little trial end error and the odd pause is usually all it takes.

These hobby motors have an operating voltage of between 3V and 6V, with 4.5V being nominal. This makes them suitable for powering with batteries. At 4.5V, they have a speed of 90RPM no-load and 72RPM at load. Torque at the nominal 4.5V is 0.3Kg/cm and they have a stall torque rating of 1.4Kg/cm. See Datasheet for more information.

Note:When using a microcontroller, do not attempt to drive these motors directly with the microcontroller, always use them in conjunction with a motor driver board.

Features:

The solderless TT motor adapter board is probably the best way of adding a TT motor to a project. Hands up if you've ever partially melted a motor or destroyed a lug whilst trying to solder wires to one? /raises hand... Not anymore! Not only is it easy to fit, it will extend the working life of your motors, especially in an educational environment. Re-use the motors over and over again. You won't even need to remove the TT motor adapter board between builds.

To fit; bend the motors lugs out approx 45 degrees from flat, place the board against the motor lining up the motors holes with the holes on the PCB, screw the two together. You can now connect to the board to your project with crocodile leads and you are good to go! Alternatively, if you want to use jumper cables instead of crocodile clips; choose one of three connection holes that is right for your project and fit some pins headers to the board. You will need the soldering iron for this one, but soldering to the PCB is a much more appealing proposition than soldering to the lugs on the motors. All the fun of soldering without the smell of burning plastic!

If you combine these solderless boards with our motor driver board for the BBC microbit, also solderless, you can build yourself a working programmable buggy/robot without a soldering iron! Just add a chassis, such as a flat piece of wood, cardboard or perspex, sticky pad everything to it and job done! This activity could also easily be done completely safely with younger children in primary education.

Features:

Add motors to your project without using a soldering iron.

Simple to fit and use.

Makes your budget go further by allowing you to reuse motors time and time again.

Suitable to use with older primary children.

Connect to the board using crocodile clips.

Alternatively, you can fit pin headers to the board and use jumper cables (soldering required).
