A compact buck module that reduces input voltage from 4 to 65 V to a stable 3.3 V at up to 700 mA. It features high efficiency, low quiescent current (<0.2 mA), and short-circuit and thermal protection, ensuring safe and efficient operation. Its small size and ease of integration make it ideal for mobile devices, battery-powered designs, and systems requiring stable power. Pololu 5432

A miniature lidar distance sensor that detects objects up to 25 cm away, regardless of color, transparency, or lighting. It generates a digital signal (0 V on detection), operates in the 3-5.5 V range, draws only 30 mA, and supports sleep mode via the ENABLE pin. Ideal for robotics, automation, and contactless interfaces, it offers a fast response time (100 Hz), switching hysteresis, and a compact housing with an indicator LED. Pololu 5480

This module provides precise, galvanically isolated current measurement within a range of ±30 A and voltage up to 480 VRMS, providing RMS, instantaneous, and active, reactive, and apparent power readings. Equipped with an I²C interface, 4-pin JST SH connectors, and 2.54 mm pins, it allows for easy integration with Qwiic, STEMMA QT, and standard microcontrollers. Configuration stored in EEPROM allows for defining address and overload thresholds. The sensor offers three voltage measurement ranges (120 V - default, 240 V, 480 V RMS) and the ability to detect overvoltages. Built-in protection and low conduction resistance ensure safe and accurate measurements. The version comes with soldered screw terminals. Pololu 5411
