Unshielded UTP category 5E Ethernet network cable with RJ45 plugs. Lanberg PCU5-10CC-0750-BK

A module with line sensors designed to work with the Kitronik kit. It has two sensors in the form of phototransistors that generate an analog voltage that can be read by the microcontroller. The module is equipped with a 4-pin connector (3V, 0V, L, R), which allows for power supply and reception of signals from the sensors, and the output voltage changes depending on the detected surface, which allows it to be used not only with the Kitronik kit, but also with platforms such as Arduino or Raspberry Pi Pico. Kitronik 56111

Module with a 12 V relay and a timer. It allows you to turn the device on and off cyclically at a specified time using potentiometers. It can also operate in single trigger mode, which allows the device to be turned on after a signal has been applied for a specified period of time. The operating time can be adjusted from 1 s to 100 s or from 1 s to 15 min
