Kitronik Audio Cable for BBC micro:bit - V1 & V2

The Prong soil moisture sensor for BBC microbit is a sensor board that can be directly mounted to a BBC micro:bit to monitor the moisture present in the soil. The two conductive tines are placed into the soil. Any water or moisture in the soil will conduct to give an analogue voltage that can be read by the BBC micro:bit.

Prong is powered from the 3V supply of the BBC micro:bit. Use either the USB or JST connector on the BBC micro:bit to power the circuit. Prong and the BBC micro:bit can also be powered from the Mi:Power board to create a compact stand-alone unit.

The board has been designed so that the BBC micro:bit can be bolted on using 3 x M3 nuts and 3 x M3 screws. Place the screws through the P1, 3V and GND holes of the PCB and BBC micro:bit, then use the M3 nuts to fasten together on the back of BBC micro:bit. Alternatively, croc-clips can be used to connect between the Prong and the BBC micro:bit.

If using the Mi:Power board then additionally connecting P0 means the BBC micro:bit can sound an alarm if the soil becomes too dry. When fitted to the Prong moisture sensor, the micro:bit can be coded via any of the micro:bit editors, such as the Microsoft MakeCode editor.

Note: To ensure that the Prong moisture sensor has a long and fulfilling life, it is better to write your code to perform a moisture check every so often rather than continuously. When the check is performed continuously it promotes rapid erosion of the electrodes.

Features:

Measure soil moisture levels.

Attaches directly to the microbit.

Use in conjunction with the Mi:Power board to provide power and an audible alarm.

Code with any microbit coding editor.

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.

Add some colour to your next coding project with our new Halo board for the BBC micro:bit. The Halo has 24 ZIP LEDs, which are individually addressable full-colour LEDs. This means that each LED can display a huge spectrum of colours, allowing amazing colourful effects to be achieved.

The Halo bolts directly onto the BBC micro:bit using five bolts which are secure and robust. The board also has extension connector pads (0.1” pitch) allowing more ZIP LEDs to be connected. The P1 and P2 micro:bit pins are also broken out to 0.1" pads along with power and GND. This allows for additional connections to low power components such as sensors and switches.

The Halo takes a supply voltage of 3.5V-5V and provides a regulated power supply to BBC micro:bit. Power can be connected using the JST input using a 3xAAA battery holder, LiPo battery, or JST lead. Alternatively, you can solder a power supply directly to the solder pads on the PCB. The LEDs used are based on the WS2812B part which is compatible with any WS2812B driver code. They can also be coded in the MakeCode Block/Javascript editor.

Features:

Halo has 24 individually addressable ZIP LEDs.

Compatible with Adafruit NeoPixel and other WS2812B driver code.

Supply voltage: 3.5V to 5V.

Halo bolts directly onto the BBC micro:bit.

The board also has extension connector pads.

Version 3 is the newest version of our best selling Mono Amplifier Kit that can be used with any personal stereo equipment, including MP3 players, making it an ideal kit choice for an amplifier case design project.

It uses an NCP2890 audio amplifier IC which is pre-mounted on the underside of the board (see image below) and can output 1.0W of power. The NCP2890 is an audio power amplifier designed for portable communication device applications such as mobile phone applications and PDAs. The IC also features an onboard “Pop and Click” at startup and closedown Noise Protection Circuit.

The kit is supplied with a pre-built jack cable, an 8ohm 66mm speaker, and a AA battery pack and can run off any voltage from 2.2 to 5.5 Volts (Absolute Maximum 6V). For a full list of parts, see the Contents section below.

Previous versions of this amp included a PP3 power connection and were designed to operate around 9V, V3.0 has been designed for use with 2 x AA batteries. There are several advantages to using AA batteries over PP3, they include; AA batteries are much cheaper, more readily available and will also last significantly longer than PP3 batteries, anything up to ten times longer.

Features:

Great value electronic project kit.

Works with any stereo equipment, including computers, phones, and tablets that can accept the jack lead.
