Overview

The Olimex USB-ISO is a full-speed USB isolator designed to protect computers and connected equipment from ground loops and electrical surges. It provides 1000V DC galvanic isolation between the host and the peripheral, making it an essential tool for debugging high-voltage hardware. This device is completely transparent to the operating system and requires no drivers for operation.

Why Choose This Part

This isolator is built in a rugged, enclosed plastic case and supports Full Speed (12 Mbps) USB 2.0 communication. It simplifies laboratory safety by removing the electrical path between the target board and the host PC without requiring complex fiber optic setups.

Applications

Safe Microcontroller Debugging
Protects expensive PC motherboards and laptops when connecting to high-voltage motor controllers or mains-connected power electronics.
Ground Loop Elimination
Prevents hum and noise in sensitive analog-to-digital measurement systems by breaking the ground path between the PC and the sensor hardware.
Industrial Communication
Ensures reliable USB communication in noisy industrial environments where large voltage transients or differences in ground potential exist.

Key Specifications

Utilized IC / Part USB

Getting Started

The device is plug-and-play; simply connect a standard USB-B cable to the host and a USB-A cable to the target device. Ensure the peripheral device does not exceed the current limits provided by the isolator, as it derives power from the host USB port.
