A4988 Stepper Motor Driver Carrier with male header pins installed, so no soldering is required to use it with an appropriate 16-pin socket or solderless breadboard. Pololu 2980

A circular board for the BBC micro:bit with 24 addressable ZIP LEDs, offering a full color spectrum and allowing for the creation of eye-catching lighting animations. Mounts directly to the micro:bit using screws, and additional pins allow for the connection of sensors or additional LEDs. Power is supplied via a JST socket or solder pads, and the built-in regulator also powers the micro:bit. The ZIP Halo is fully compatible with NeoPixel libraries and can be programmed in MakeCode or MicroPython. Kitronik 5625

Module with 16-channel IO expander MCP23017 controlled by the I2C interface. Designed for minicomputers Raspberry Pi. Adafruit 4132

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 7.5 V. The board measures only 0.7″ × 0.7″, but it allows a typical continuous output current of up to 2.5 A. Typical efficiencies of 85% to 95% make this regulator well suited for powering moderate loads like sensors or small motors.

LED module dedicated to low-power lighting, ideal for desk lamps and creative lighting housings. Equipped with a micro USB connector, it is easy to power from computers or laptops, and thanks to its compact dimensions and simple layout, it can be easily integrated into various projects, offering the possibility of connecting an additional switch.

Crowtail – BME280 Atmospheric Sensor 2.0 is a multifunctional environmental sensor measuring temperature, humidity, and pressure, with an I2C interface and low power consumption. It is used in weather applications, home automation, and mobile systems.

The compact (0.4″ × 0.5″) D24V5F12 synchronous buck voltage regulator takes an input voltage of up to 36 V and efficiently reduces it to 12 V while allowing for a maximum output current of 500 mA.

An 8MP camera designed to work with NVIDIA Jetson boards, as well as other systems such as ARM, DSP, and FPGA, offering a wide field of view and high image quality. The camera is very sensitive to infrared light due to the lack of an IR filter, which allows it to be used in applications such as night vision systems, heat detection, and robotic vision systems. ArduCAM B0193

Bluetooth module with integrated HC-08 system. Thanks to the angular pin connector with the bus signals, it is possible to easily connect the module to the contact plate or wires

The compact (0.4″ × 0.5″) D24V5F6 synchronous buck voltage regulator takes an input voltage of up to 36 V and efficiently reduces it to 6 V while allowing for a maximum output current of 500 mA. Pololu 2844

IR proximity sensor used to detect objects at a distance of 10mm to 80mm using infrared radiation. It is powered by 5 V and has a digital output. DFRobot SEN0556

An expansion board for the BBC micro:bit, allowing easy connection and control of low-power servos. It supports two servos by default, and up to three by disabling the built-in ZIP LEDs. Powered by three AAA batteries, it simultaneously supplies power to the micro:bit, while a power switch protects against unnecessary discharge. With five RGB ZIP LEDs and the ability to connect additional ones, the board allows for attractive lighting effects and is ideal for robotic projects like the :MOVE mini. Kitronik 5623
