Knob with an inner diameter of 6 mm for mounting on a rotary potentiometer. Purple color

A module that provides galvanically isolated, bidirectional I²C communication and isolated power supply, protecting devices from misconnections and voltage differences. Thanks to the TI ISO1640B device, it supports data transfer up to 1.7 MHz, and the power supply isolation via MPS MIE1W0505BGLVH eliminates ground loops and interference. Pololu 5392

The Arducam B0462 camera module with the GC2145 color sensor offers 2 MP image capture with low power consumption. Its wide compatibility with the Arduino GIGA R1 platform makes it suitable for use in embedded systems, robotics, and real-time image analysis.

Module with 512 kbit (64kB) EEPROM. Communication is via the I2C interface. The module has 3 jumpers to select one of 8 addresses. SparkFun COM-18355

Pololu 5651 is an adapter that enables integration of JST PH and SH wires with circuits using a 2.54 mm pitch. Thanks to its compact design and the side-entry PH connector, it is suitable for projects with limited space and where wires need to be routed parallel to the PCB.

A compact converter designed to drive LEDs in series and parallel circuits. The device generates voltages up to 40V and currents up to 400mA from a 3-5V supply, with the output current adjustable via mini DIP switches. The board features a built-in 1.2A switch, overvoltage protection, and PWM LED dimming. Adafruit 6354

A compact Hall-effect current sensor that provides accurate DC and AC current measurement within a ±30 A range with galvanic isolation. It features a high-sensitivity analog VOUT output with a 150 kHz bandwidth, enabling fast and precise readings in dynamic systems. The module operates over a wide temperature range of -40°C to 125°C, and the low current path resistance minimizes energy loss. Its small size and flexible mounting options make it ideal for prototyping, industrial systems, and space-constrained projects. Pololu 5447
