Module with three 4-20 mA analog outputs. It communicates via the RS485 interface and supports the Modbus RTU protocol. The board is enclosed in an industrial housing. Wellpro WP3078ADAM

This stepper motor driver offers microsteps down to 1/256th of a step, ensuring exceptional precision and smooth motion. Its simple operation—requiring only two microcontroller pins—and low operating voltage (1.8 to 10V) make it ideal for energy-efficient mobile, robotic, and DIY applications. Integrated connectors, LEDs, and a potentiometer for current adjustment facilitate prototyping and secure integration with popular platforms like Arduino and ESP32. Adafruit 6353

LED strip with addressable RGB WS2815 diodes on a white PCB. It is powered by 12 V DC, has a length of 1 m and 30 LEDs/m. Protection level IP67

Module with an active buzzer. The board is equipped with a Grove connector and is controlled by a digital signal. Seeed Studio 107020000

Photon Micro OLED Shield breaks out a small monochrome, blue-on-black OLED to use with your Photon module. It’s “micro”, but it still packs a punch – the OLED display is crisp, and you can fit a deceivingly large amount of graphics on there. DEV-13628

Universal silicone cover that protects the LED strip against moisture, water and dirt. Provides protection in accordance with the IP67 standard

Module with 16 digital outputs. It communicates via the RS485 interface and supports the Modbus RTU protocol. The board is enclosed in an industrial housing. Wellpro WP8027ADAM

Module with 8 relays with a maximum switching current of 2 A. It communicates via the RS485 interface and supports the Modbus RTU protocol. The board is enclosed in an industrial housing. Wellpro WP8025ADAM

This module allows you to automatically turn on LEDs in the dark thanks to a built-in light sensor. It comes with a CR2032 battery holder and a slide switch to turn the module on and off. It also has two sets of pads for connecting LEDs, allowing for flexible lighting design. Kitronik 2721

The :MOVE mini MK2 robot kit allows for automatic line tracking, enhancing the interactivity of educational projects. The kit is easy to assemble, requires no soldering, and adjustable sensors allow for precise sensitivity adjustments for the left and right sides of the robot. The module can track both a dark line on a light background and a light line on a dark background, and backward compatibility with the original :MOVE mini makes it easy to use in older projects.
