Module with 2 QTRX type optocoupler with analog output. The module operates from 2.9 V to 5.5 V, detects objects at a distance of up to 30 mm. The sensor will be used in projects that require detection of changes in the ground, e.g. in linefollower robots. Pololu 4402

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

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

A complete starter kit for creating projects with e-textiles and micro:bit, ideal for beginners, hobbyists, and educators. The box includes sewing LEDs, 5mm diffused LEDs, conductive thread, and alligator clips, allowing you to start experimenting right away.
