Kitronik 3V Vertical Submersible Water Pump

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.

Looking to do more with your BBC micro:bit? Unlock its potential with this ‘pre-built’ version of the Edge Connector Breakout Board! This breakout board has been designed to offer an easy way to connect additional circuits and hardware to the pins on the edge of the BBC micro:bit. It provides access to all of the BBC micro:bit processor pins allowing a lot of extra functionality to be added. The datasheet (below) includes a helpful diagram explaining the function of every pin on the BBC micro:bit.

This Edge Connector Breakout Board for the BBC micro:bit gives access to all of the important pins on the bottom edge of the BBC micro:bit. 21 pins are broken out in total; providing additional I/O lines, direct access to buttons A and B, the LED matrix outputs and the I2C bus. Please refer to the datasheet below for more details.

The BBC micro:bit pins are broken out to a row of pin headers. These provide an easy way of connecting circuits using jumper wires. The SCL and SDA pins are separated at the edge of the board (solder pads) providing easy identification. The PCB includes a prototyping area with 3V, 0V and unconnected rows that can be soldered to. This allows the easy connection of switches, sensors and any pull-up or pull-down resistors etc. as required.

To use the breakout board the BBC micro:bit should be inserted firmly into the connector.

Features:

Features a dedicated pin strip for quick and easy prototyping.

Breaks out 21 pins from the edge of the BBC micro:bit.

Dedicated prototyping area with 3V and 0V rows.

Labelled pins and clear straightforward documentation.

Raspberry Pi Pico

Micro:Bit

The MI:sound board is a speaker board for the BBC microbit. It features on-board; speaker, CR2032 battery holder, thumbwheel volume control and an easy access on/off switch. The MI:sound board can either be powered by the CR2032 battery (provided) or via the micro:bit USB or JST connections. It has been designed to work with micro:bit V1 and micro:bit V2.

The speaker on MI:sound can be used in conjunction with the micro:bits onboard speaker or instead of. The micro:bit speaker can be turned off as there is a command/block for that in the MakeCode editor. Why would you want to? Volume! MI:sound's speaker is loud, and the potentiometer gives you control over its volume without the need to head back into the code. Super convenient!

To use the MI:sound speaker board, the BBC micro:bit should be attached using the supplied bolts, spacers and nuts. Only Pin 0, 3V and GND need to be connected. Crocodile clips can also be used.

When assembled, the MI:sound board is connected directly to the 3V, GND and P0 connections on the micro:bit. The 3V and GND connections provide power to the micro:bit and the built in buzzer is connected to P0, which is the default output pin when using the audio functions in the MakeCode software. The board has an easy to access on/off switch, which makes it easy to turn a project on and off.

Like the MI:power board, MI:sound offers an elegant solution for micro:bit projects on the move. Both boards provide power to micro:bit, feature an on/off switch and allow you to output sound. Sound though is a much bigger feature on the MI:sound board. Where the MI:power board features a buzzer, MI:sound has an actual speaker with a thumbwheel volume control. Not only is the speaker more versatile than a simple sounder, it is also much much louder. So, in brief; the MI:power board is more compact and MI:sound is better for projects where sound is an integral part of the project.

Features:

Power your BBC micro:bit from a stylish PCB.

It features an on-board speaker and it's loud!

There is a thumb wheel operated potentiometer volume control.

There is an onboard CR2032 battery holder.

The board features easy access on/off switch.
