Kitronik Mini 180° Servo Resin Gear SG90

Micro:bit V2 is a tiny, programmable computer board designed to teach kids and beginners about coding, electronics, and robotics. The board features a range of sensors, buttons, and LED lights that can be programmed using various programming languages and visual programming tools.

Now includes both a speaker and microphone as well as many of the same great features students have used for years. It's easier than ever to use sound and touch to get creative in the classroom.

Using the micro:bit V2, students will be able to sense and react to sound with the built-in microphone and play sound with the built-in speaker while coding in MakeCode, Python, or Scratch!

With the Kitronik Compact Robotics Board, the BBC micro:bit can be used to drive 4 motors (or 2 stepper motors) and 8 servos. Coupled with 17 other I/O expansion points, this means the BBC micro:bit can very easily become the core of a whole variety of robotics projects. The board is small on footprint but big on features and connectivity. Please note, when used with a stepper motor, half-stepping is supported - but not micro-stepping.

The Robotics Board features 2 Dual H Bridge Motor Driver ICs (capable of driving 2 standard motors or 1 stepper motor each) and 8 servo outputs (capable of driving standard and continuous rotation servos), all controlled from the BBC micro:bit using the I2C protocol via a 16 channel driver IC. Kitronik's custom MakeCode blocks make using I2C easy, even for novice users.

The Link header breaks out all the usable pins from the BBC micro:bit, and is designed to allow 2.54mm pitch pin header to be easily soldered into place. The 17 available I/O pins allow other input devices, for example, sensors, or output devices, such as ZIP LEDs, to be added to the board. The I2C communication lines are also broken out (Pins 19 & 20), which means other I2C compatible devices can also be added to the board and controlled by the BBC micro:bit.

Power is provided via either a terminal block or servo style connector. The supply is then controlled by an on/off power switch to the board. There is also a green LED to indicate when the board is turned on. The board then produces a regulated 3.3V supply which is fed into the 3V and GND connections to power the connected BBC micro:bit. This removes the need to power the BBC micro:bit separately. The 3V and GND pins are also broken out on the Link header, which means external devices can also be powered.

To use the compact robotics board, the BBC micro:bit should be inserted firmly into the edge connector, with the LEDs and buttons visible from the front.

Kitronik has produced a set of custom blocks for the MakeCode editor to simplify using the Compact Robotics Board for BBC micro:bit. To add them to the editor, select the cog icon in the top right of the editor. Then, select Extensions from the drop-down menu and in the search bar type and enter Kitronik. Pick the Kitronik robotics Board from the list and the new blocks will be added to the menu in the editor.

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.
