A compact board that allows for easy connection of a standard SPDT "sugar cube" relay in electronics projects. An integrated MOSFET transistor allows for relay control using a 2.5V to 20V logic signal, and two LEDs indicate its status. The module is equipped with a 3-pin JST SH connector and 5mm terminal holes for easy installation and integration with microcontrollers. Pololu 5664

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

Step-down voltage regulator module based on the APM81815 providing a fixed 5 V output at up to 1.1 A with an input voltage range of 5.05 - 72 V. Pololu 5267

An advanced FPGA platform based on the Altera Stratix 10 TX, designed for ultra-high-throughput sensor data processing. It supports direct data streaming to the GPU using NVIDIA Hololink IP and GPUDirect RDMA, ensuring extremely low latency. Dual 100GbE (RoCE v2) interfaces and an FMC+ connector enable integration with advanced sensor modules and JESD204C interfaces. TerasIC P0817

Ultrasonic distance sensor MB1000 with a range from 0 to 645 cm. It has an output in the form of a serial interface, an analog signal or generates an impulse whose duration is proportional to the measured distance. Pololu 723
