This module allows independent control of two Omron G5LE-14-DC12 SPDT relays, supporting currents up to 10A. Thanks to built-in BSS138K MOSFETs, it can be controlled directly from 3.3V or 5V development boards such as Arduino or Raspberry Pi. Each channel is equipped with an LED to indicate relay activation and 5mm screw terminals for convenient circuit connection. Pololu 5666

DIP8

USB converter <-> UART, LQFP32, RoHS

A precision reflective sensor utilizing an IR diode and a phototransistor to measure light reflected from a surface. It offers an analog voltage output proportional to the reflected light and an optimal measurement range of 10 mm. Its low power consumption and compact size make it ideal for line-follower robots, edge detection systems, and educational projects. Pololu 4440

This step-down converter module allows you to reduce the voltage from 15-60V to a stable 15V at a current of up to 8A. Its high efficiency of up to 95% and low power losses make it ideal for applications requiring high current and stable power. The device features built-in overcurrent, thermal, and reverse connection protection, as well as a soft-start function and a Power Good indication. Pololu 5679

The RS-485 / RS-422 transceiver from Maxim Integrates in the SO8 housing, allows the transmission of a signal with a throughput of up to 2.5Mbit / s, it has the ability to support up to 32 devices on a shared bus

A communication module based on the Raspberry Pi RP2040 microcontroller, designed for data transmission in the 868 MHz band.
