Kitronik Yellow Wheels

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.

Micro:Bit

Add motor driving capability to the microbit with the Kitronik compact motor driver board for the BBC micro:bit. This motor driver board allows two motors to be driven simultaneously with forward, reverse & stop control, making it ideal for designs such as buggies. The board has a built-in short circuit, over current and thermal protection. Please note, when used with a stepper motor, half-stepping is supported - but not micro-stepping.

The board includes an integrated Edge Connector for your BBC micro:bit to slot into easily. It also features external connections to the button A and button B inputs. This allows additional switches/inputs to be connected to the motor driver board and the state of these can then be read by the BBC micro:bit.

There are 2 additional inputs/outputs. These can be used for connecting a range of parts and can be used in either digital or analogue modes.

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 a green LED to indicate when the board is turned on. The board also produces a regulated 3V supply that is fed into the 40 way connector to power the inserted BBC micro:bit, removing the need to power the BBC micro:bit directly.

Kitronik has produced a set of custom blocks for the MakeCode editor to simplify using the Compact motor driver board. 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 motor driver tile from the list and the new blocks will be added to the menu in the editor.

Features:

Ideal for designs such as buggies and other robotics projects.

Drive 2 motors with full forward, reverse and stop control.

Terminal blocks for easy connection of motors and inputs.

The 2 additional inputs/outputs can be used in either digital or analogue modes.

This board also features an on/off switch and power status LED.

Includes Edge Connector for the BBC micro:bit to slot into.

Provides regulated power to the BBC micro:bit.

Access the other BBC micro:bit pins easily and conveniently.

Program with the MakeCode editor or with python.

When used with a stepper motor, half-stepping is supported - but not micro-stepping.

This Kitronik MI:pro Protector Case for the BBC micro:bit has been designed to work with both the original Micro:bit V1and the new Micro:bit V2and continues in the traditions of our earlier cases. The cases are designed to keep the micro:bit safe, fully useable, and to offer the freedom of not being tethered to a computer.

If a battery holder is attached to the back it can also can be stood neatly on a desk and it also features large and easy to read labels for the A and B buttons. This case provides full access to the bottom pins on the BBC micro:bit so the Edge Connector Breakout Board for the BBC Micro:bit can be used. One of the key features of the micro:bit is its physical size and this case has been designed with that in mind. It's as compact as we could make it, whilst still offering protection for the micro:bit.

The case is also supplied with a sticky fixer pad so that you can attach a battery holder to the rear of the case, such as can be found in our BBC micro:bit Starter Kit. When a battery holder is used, micro:bit projects can go wherever you go. Even with a battery holder attached, the case is still palm-sized and portable.

Note: This case requires assembly, full instructions can be found in the resources section below.

Features:

Provides excellent protection to the BBC micro:bit whilst allowing access to the bottom pins.

Full access to the A and B buttons on the BBC micro:bit.

Attach a battery cage to the rear of the case with the supplied sticky fixer.

Full access to pins and connections including the micro USB connector.

Clear case material shows the on-board LEDs in perfect clarity.

The case is compatible with versions 1 and 2 of the micro:bit.

When used in conjunction with a battery holder, micro:bit projects can be fully mobile.
