ElecFreaks micro:bit Smart AI Lens Kit

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.

Display meaningful output from your micro:bit project with the Kitronik :VIEW Graphics128 OLED display. The Kitronik :VIEW Graphics128 OLED display gives the user the ability to add a monochrome 128x64 display to the BBC micro: bit. The onboard edge connector allows the micro:bit to slot into the board without any additional fixings. The board also features a micro:bit style I/O connector which means it can be slotted into any other micro:bit accessory that has a slot for inserting a micro:bit. All of the pins from the BBC micro:bit are tracked through to provide the edge pads with the full usage of the BBC micro:bit, with the addition of a display. As the micro:bit slots directly into the board, no tools, fixings, or soldering are required.

Power to the board can be provided via the edge connector or from the micro:bit. The board requires a 3V supply and has no voltage protection on the board. The board features an LED to indicate when the board has power. With every display, pixel turned on the board has a maximum power draw of 40mA. The 128x64 display uses the SSD1306 driver on an I2C interface. At the centre of the board are the breakout pads for the I2C lines, along with two ground pads and a 3V power pad. These pads are on a 2.54mm pitch, which means they will fit either wire or a pin header for jumper cables (not provided). This can be used by those who wish to add more I2C devices and functionality. It is possible to change the default I2C address of the board (see the Selecting Display section of this Datasheet for more details).

Features:

Add a monochrome 128x64 OLED display to the micro:bit.

The micro:bit slots into the onboard edge connector.

The board features a micro:bit style I/O connector allowing it to be slotted into other micro:bit accessories.

It can be coded with MakeCode blocks and with Python.

Kitronik has created custom MakeCode blocks.

Kitronik has created a GitHub repo for custom Python functions.

It can be powered via the edge connector or by the micro:bit.

Requires a 3V supply.

The board features a power indicator LED.

It is possible to change the default I2C address of the board.

No tools, fixings, or soldering are required.

Raspberry Pi Camera Module 3 is a compact camera from Raspberry Pi. It offers an IMX708 12-megapixel sensor with HDR, and features phase detection autofocus. Camera Module 3 is available in standard and wide-angle variants, both of which are available with or without an infrared cut filter.

Camera Module 3 can be used to take full HD video as well as stills photographs, and features an HDR mode up to 3 megapixels. Its operation is fully supported by the libcamera library, including Camera Module 3’s rapid autofocus feature: this makes it easy for beginners to use, while offering plenty for advanced users. Camera Module 3 is compatible with all Raspberry Pi computers.

The PCB size and mounting holes remain the same as for Camera Module 2. The Z dimension differs: due to the improved optics, Camera Module 3 is several millimetres taller than Camera Module 2.

Key Features:

Back-illuminated 12-megapixel Sony IMX708 sensor

High signal-to-noise ratio (SNR)

Integrated 2D Dynamic Defect Pixel Correction (DPC)

Fast Phase Detection Autofocus (PDAF)

QBC Re-mosaic function

HDR mode supporting up to 3-megapixel output

CSI-2 data output

I2C fast-mode compatible serial communication

2-wire serial control for focus mechanism

Compatible with:

Raspberry Pi 4

Raspberry Pi 5

Raspberry Pi Zero

The Raspberry Pi 5 includes two MIPI connectors designed for camera modules or displays. These connectors are more compact than those on previous Raspberry Pi models, so an adapter cable is required to connect your camera module.

Cable length: 200mm

These adapter cables feature a 22-pin, 0.5mm-pitch connector on one side for the Raspberry Pi 5, and a 15-pin, 1mm-pitch connector on the opposite side.

These camera cables DO NOT work with DSI displays.
