This is a micro servo It only weights 20g and provides a 1.6kg.com torque. It will comes with a 3-pin control cable and mounting hardware.

Almost all the micro bit servo in the market have to be driven by 5V, but the normal working voltage for micro:bit is 3V. It is embarrassing to drive a 5V servo with a micro:bit. Thus, we have customized these two servos that can be driven by two batteries with the lowest working voltage at 2.7V. It is the first batch of the micro bit servo designed for the micro:bit in the market.

The high linearity makes its control more accurate. It is designed for micro:bit with high-linearity, which gives you a smooth feel of control.

Low working voltage, compatible to 3V-5.5V(With 2.7V at least), designed for micro:bit.

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.

A flow rate of 80L/H @ 3V and 100L/H at 4.5V.

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:

Kitronik's Linear Actuator converts the circular movement of a 180° servo (supplied) into motion in a straight line, one way and then the other. It can be mounted to a project to provide either horizontal or vertical movement.

Linear Actuators are useful for a whole host of different applications, like; robots, automated button switching, steering racks for buggies, a point switcher on a model railway, animating a diorama display, etc. Linear actuators are also used extensively in industry and in consumer products, such as; valves, cams, floppy disk drives and optical disk drives, just to name a few.

The Linear Actuator has been cut from a 5mm clear blue Perspex Sheet, the same material as used in our servo powered Klaw gripper. There are a range of mounting holes at either end of the rack including a 3mm hole, a 3mm square, and standard servo horn holes suitable for wire (1mm dia) and it has approximately 20mm of travel. It has a gear ratio of 2:3 and the stall torque of the provided servo is 1.5kg/cm at 6V and 1.3kg at 4.8V.

Features:

The Linear Actuator converts the circular movement of a 180 degree servo (supplied) into motion in a straight line.

It is supplied with a 180 degree FS90 servo and fixings.

Useful for a wide range of applications, such as; robotics, switching, animating displays and more.

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.
