Our Micro Metal Gearmotor family consists of tiny brushed DC metal gearmotors with nitride-hardened martensitic stainless steel gears in a wide range of gear ratios, motor windings, brushes, and encoder configurations: Micro Metal...

The D42V55Fx family of synchronous buck (step-down) voltage regulators generates lower output voltages from input voltages as high as 60 V. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC...

This USB-to-I²C adapter functions as a bridge between I²C devices and a PC or other USB host, enabling the USB host to serve as an I²C controller and communicate with target devices on the I²C bus. It supports bidirectional communication...

This board functions as a solid state, single-pole, single-throw (SPST) relay or switch that can be activated by a low-current control signal between 2.7 V and 40 V. The switching is performed by a pair of MOSFETs controlled by an...

We are offering these breakout boards with support from Allegro Microsystems as an easy way to use or evaluate their ACS37800KMACTR-030B3-I2C isolated power monitoring IC; we therefore recommend careful reading of the ACS37800 datasheet...

These 0.1" straight female header strips are commonly used as low-cost connectors for custom-made cables or perforated prototyping PCBs . The standard spacing is the same as on most solderless breadboards and matches 0.1" male header...

This module enables galvanically isolated (electrically isolated), bidirectional communication between two I²C devices. This isolation means current cannot flow from one side to the other, and incorrect connections or bad voltages on one...

Pololu Reverse Voltage Protectors are compact modules that can be inserted between a power supply and its load to protect that load from damage in the case of accidental reversal of power polarity. They operate from 4 V (3.2 V after...
