## Overview

The GeeekPi USB Digital Isolation Module uses ADuM3160 technology to provide robust 5KV ESD and overcurrent protection for USB 1.0/1.1/2.0 full-speed devices. Designed to prevent damage from short circuits and surges, it supports data rates up to 12 Mbps and features a red LED fault indicator. Ideal for USB debugging, industrial devices, and DIY electronics, this compact isolator safeguards your computer, microcontrollers, and development boards without compromising USB functionality.

## Description

This USB isolator is made for someone leads to burning the USB port of the computer device or the host device,and even burning the motherboard. Some electronic enthusiasts use the bare electronic device but may damaged the device accidently by some wrong operation. When you DIY a new circuit board, but there may be a short circuit or the current is too large, plugged into the computer for testing,causing the USB port to burn down or the motherboard is damaged. We have created a hardware device that can prevent this situation. Known as USB isolation.Its biggest feature is to prevent accidental surge attacks and prevent short circuits when you use USB properly. It is the protection of your computer, microcontroller, Raspberry Pi and other electronic devices! Protect your computer or the USB port of your development board without affecting your USB device use! When a short circuit condition occurs, a red light will be lit on the USB isolation device, which will remind you that the access device is short-circuited and will not cause damage to your computer. The USB Isolator is based on ADuM3160 component.Combining high speed CMOS and monolithic air core transformer technology, this isolation component provides outstanding performance characteristics and is easily integrated with low and full speed USB-compatible peripheral devices. Many microcontrollers implement USB so that it presents only the D+ and D− lines to external pins. This is desirable in many cases because it minimizes external components and simplifies the design;however, this presents particular challenges when isolation is required. Because the USB lines must switch between actively driving D+/D− and allowing external resistors to set the state of the bus,the ADuM3160 provides mechanisms for detecting the direction of data flow and control over the state of the output buffers.

Review: Looks to work good - I've been playing around with several different small board programmable modules, and wanted to make sure any screw up in the breadboard wiring, etc, didn't make it back to my PC. So far appears to be good at isolating it
Review: Does what is says, for all the tests I tried. - Does what it says. I tested it with a Klein Tools ET920 USB Tester, and a resistance-subsitution-box..which allows one to incrementally adjust to less and less resistance. I got it all the way down to 1 ohm, and 1.3 amps. I did not try this setup with data simultaneously, as I cut the test USB cord in two. I also test this device with the wires shorted in the usb cable (the power wires), and it got 1.03 amps...which is sort of interesting, since they are the same wires that just before had an additional 1 ohm of resistance in the loop...yet had MORE amperage. But, it was close to the same. Likewise, I ran Arduino Micro through it, with USB and tested up to 2Mbps, quiet successfully. I'm looking to use some other kind of microcontroller and test up to the full 12Mbps. I did try two of my external-USB-Harddrives and neither would usb-post. They were only looking for about 0.58 amps when trying to spin up, and about 0.4 amps. So, since tested it to 1-1.3 amps with the shorted USB-cord, then my drives must not have worked, simply due to not enough USB-throughput with this isolator. I had hoped to connect things like Oscilloscopes and other expensive test Equipment through one of these. But, the low bandwidth, and USB 1.0 only compatibility is keeping it from working it looks like.

## Questions & Answers

**Q: Would this help when connecting phone to computer for streamng. I get a horrible buzz sound when connecting phone to computer by usb.**
A: This is not recommended for connecting mobile phone and computer

**Q: Will this give full 5v power isolation from spikes and noise?  Want to make sure it isolates the power as well.**
A: I am using this to run a debug pod, and it works perfectly.  It has isolated power WITH AN EFUSE, so it won't burn out if you pull too much power from it.

Not sure how much isolation you get from spikes and noise, but it has electrical isolation and it looks like it's good to the rated voltage.  I haven't hipotted it, but visually it looks like the design is correct for the specs.  High frequency components of spikes and noise will couple through the isolation somewhat, but I don't know how much.

**Q: I need power and signal isolation. does this device provide complete isolation of all aspects of the usb connection?**
A: Yes, you can refer to this wiki:　https://wiki.52pi.com/index.php?title=EP-0101

**Q: Overcharge of t-mobile hotspot t10, is this device protecting my franklin t10 from battery overcharging when permanently connected to power?**
A: No,it cannot protect against overcharging, but only against short circuits and protect the circuit.

### ⭐ Fantastic for ground loop buzz! DAC/AMP/PC loop
*by V***K on November 20, 2022*

Update. Lasted 2 days, died. Replacement lasted a day, died. Garbage. These reviews seem all over the place and I suspect its due to being used for issues this is not intended to solve.. I used this to get rid of a very annoying albeit subtle ground loop buzz/hum whatever you wna call it that Id been dealing with for over a year lol. I was looking at products that cost 6 times as much and nearly bought them before deciding this was so cheap that even if it didnt work, nbd.. Well it works, perfectly. Plugged in and issue gone. See if these specifics match your system/issue to determine if it may help. I have a DAC/AMP connected to my PC via a single USB. The USB is both power and data. Id read if you feed your DAC/AMP via a dedicated power supply then that may fix your issue. Didnt try it so idk about that. I had a constant hum/buzz as soon as I launched any game or audio app. It was quiet, so when you played music or actually started getting game audio, itd be drowned out, but in quiet moments it was always there and eventually began to drive me insane lol. Plugged this in and noise gone! Dead silence! This needs to be upstream of the DAC/AMP. So it goes as follows, PC-this dongle-USB cable-DAC/AMP. Good luck!
