What does the Kittenbot Iobit have to offer – The Kittenbot Iobit is a feature packed and affordable expansion board for the BBC Micro:bit, which can be used to extend the various IO ports of the BBC Micro:bit. The Kittenbot Iobit makes using the BBC micro:bit and working with different electronics projects a lot easier. The Kittenbot Iobot takes all the IO pins on the Micro:bit and extends them on easy to access pins with a buzzer and button on board. The buzzer is connected to the P0 pin through the jumper cap. The P0 pin can be released using a jumper cap. The Iobit also comes along with Gold Finger pin breakouts for Pin 0, Pin 1, Pin 2, 3V and GND very similar to what you would experience when working with the BBC micro:bit. The board also comes along with an audio connector which means you can play music and listen to it while you code.

On of the key advantages of the Kittenbot Iobit is that you can use it to power 5V sensors using the 5V pins which is something you can’t do with the BBC micro:bit since it’s a 3V device. Also, the small form factor of the Kittenbot Iobit makes it easy to fit into any small or large projects you might be considering for your BBC Micro:bit.

Please Note : The Kittenbot Iobit does not come along with a BBC micro:bit or the Kittenbot Mewobit. Each of these items needs to be purchased separately.

What are some of the main features of the Kittenbot Iobit

  1. Small size, very suitable for DIY.
  2. All IO ports are extracted.
  3. On-board buzzer: you can directly use the music module in MakeCode to play music. At the same time, the 3.5mm audio connector on the board can be connected to audio equipment; such as, headphones to have more creative endeavors.
  4. Two LEGO-compatible pin holes for easy assembly and integration.
  5. The 3PIN interface is distinguished by yellow, red, and black. It is created so that plugging it in the wrong way is difficult, and it is convenient to plug in the sensors.
  6. It imitates the 5PIN gold fingers on the Micro:bit. This is convenient for makers who like to use the alligator clips.
  7. Compared with IObit1.0, the biggest difference is that it can input and output 5V, support 5V sensor use, and increases the drive capacity (can drive multiple 9g small servos).
  8. Includes 1A self-recovery fuse.
  9. Custom-designed silk screen board.

What are some of the key technical features of the Kittenbot Iobit – Let’s have a look at the Kittenbot Iobit below and explore the capabilities of the board.

  1. Power supply mode: IobitV.2.0 supports USB5V power supply. This power supply mode requires pressing the blue power switch.
  2. Working voltage: 3V-5V (5V sensor module is not supported under 3V power supply).
  3. Output current: 3V and 5V power interface with maximum output 1A.
  4. Serial port extraction: serial port can map IO port.
  5. I2C port leads: pins 19 and 20 can only be used as I2C function pins. They cannot be read and written as ordinary IO ports, because Micro:bit bottom is dead.
  6. Spi port leads; 14, 15 (IO port can be read and written).
  7. Length x width x height: 57mmx44mmx12mm.

All the pins in the Micro:bit have been taken out without any reservation (Note: there are no P17 and P18 on the Micro:bit, it’s not that the IObit is not taken out). Yellow corresponds to the different IO pins, Red corresponds to 3.3V/5V (with silkscreen) and Black corresponds to GND. The gold fingers of the Micro:bit are used to draw 3v, gnd, P1, P2, and P3 respectively. This is for users who prefer to use alligator clips.

Here are a few things to keep in mind when you are working with the Kittenbot Iobit – If you use P0, remember to turn the buzzer toggle switch off (because the buzzer is combined with P0).

  1. When using the Micro:bit power supply, IObit IO port drive capability is very weak, IO port current is less than 200mA, please do not connect high current devices (such as large servo MG995, DC motor), otherwise it will burn out the Micro:bit , you must fully understand before using what the device current conditions needed
  2. When using a 5V external power supply, you can drive multiple small servos, but please note that the maximum current is 1A!
  3. If you use the high-low read function of the pin, you must set the pull-down on the pin.
  4. If P0 is used as a normal IO port, the buzzer toggle switch must be turned off, otherwise the buzzer will sound or the IO read value will be abnormal.
  5. Use the shared pin with the Micro:bit dot matrix (such as 3, 4, 5, 6, 7, 8, 9, 10, 11), remember to disable the dot matrix screen on the software, otherwise it will be a bit of a screen burst
  6. Do not use IO19, 20. 19 and 20 cannot be used as an IO port. Although the display on the MakeCode software can be used, it is actually not used! It can only be used for I2C communication
  7. The USB port allows a maximum input current of 1A.
  8. Do not place it on a metal surface to avoid short circuit

The Kittenbot Meowbit is quite a powerful programmable computer that can be programmed using both Makecode Arcade (Block based coding platform) including micropython. It also allows you to re-use any other BBC micro:bit addons you might have invested in. Combined with the Iobit v2.0 or the Robobit 2.1 you can further extend the capability of the Kittenbot Meowbit.

How do we program the Kittenbot Iobit : The Kittenbot Iobit when used with a BBC micro:bit can be programmed using either the Makecode Block Editor, using Javascript within the Makecode editor, using the Mu Python editor or using Kittenblock (Based on Scratch 3.0). You can find each of these options listed at the Kittenbot Software Download website.

Let’s look at each of the programming platforms very briefly –

  1. The Block Editor is a visual editor and provides an introduction to structured programming via drag and drop coding blocks that snap together. You can also convert a Block Editor script into Javascript which helps with the transition to text-based programming. Find out more at the Makecode for BBC micro:bit website.
  2. For those who have been working on Block based programming for a while and are considering moving to Javascript, the Makecode Arcade development platform offers you the flexibility to write code in Javascript too. In-fact all the block based code that you write can be directly translated to Javascript. Javascript is also back in popularity as a web programming language for development of interactive websites. Find out more at the Makecode for BBC micro:bit website.
  3. You can also use Kittenblock which is a block based programming language based on Scratch 3.0. You can read up more and download the Kittenblock software at the Kittenbot Software Download website. Documentation for Kittenblock can be access through the following link  – Kittenblock Scratch 3 tutorials.
  4. MicroPython is a completely text-based programming language, perfect for those who want to push their coding skills further. A selection of ‘tutorials’ are on hand to help auto-complete trickier tasks and a range of pre-made images and music are built-in to give you a helping hand with your code.  Read more at the Micropython website.
