ElecFreaks Servo 360degree EF90A for micro:bit

360 Digital Servo(EF90D) with wheel and tire is a kind of 360° analog servo. It is light and portable, a little bigger than 5 cent coin. It works at 3V voltage and uses pulse width to adjust speed of the servo rotation, which also can be used to make small robot modules, mechanical arm modules and intelligent car modules.

EF90D micro:servo 360 degrees digital servo for micro:bit

Wheel

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.

Develop your coding skills with the Kitronik :MOVE Motor for micro:bit, a fun introduction to buggies and robotics. The Kitronik :MOVE Motor for the BBC micro:bit provides a fun introduction to buggy robotics. More than just a programmable buggy, learning to use all of the included features will give the budding roboteer a solid grounding in robotics as a whole.

Learn about movement, how to utilise light and sound, obstacle detection and avoidance, and how to code :MOVE Motor to follow a line. When used in conjunction with the micro:bit's radio features, the possibilities are endless.

Attached to the chassis are two bi-directional DC motors with variable speed control. The wheels have rubber tyres and are a simple push-fit onto the motor shafts. Slot a BBC micro:bit into the edge connector and you are ready to code. There is no other assembly required and no tools required.

There are built-in battery holders for 4x AA batteries. This provides a regulated voltage supply to power the BBC micro:bit which is fed into the edge connector. There is also a power switch to conserve batteries when the buggy is not in use. The micro:bit slots into the onboard edge connector. Code the micro:bit, plug it into the buggy, switch the power on, and then play.

The :MOVE Motor Klaw provides a fun and easy to install addition to the Kitronik :MOVE Motor buggy for microbit. It has been carefully designed to have the ability to fit both vertically and horizontally with one bolt. Included are two types of Klaw attachments for each of these builds.

It is controlled by a low voltage servo which is included, this servo is used to open and close the Klaw. The voltage supply and control signal are all from the :MOVE Motor via the pin headers, simply connect the servo lead onto the pin headers.

The :MOVE Motor Klaw can be coded with MakeCode or with MicroPython and we have produced online guides to walk you through both. These guides can be found in the list of resources below along with the build instructions.

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.

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.
