Study the documentation carefully and you will be able to utilize the devices to their full potential. I have not tested the devices with more than 100ft of cable . Review: Didn't Work - Bottom line, it didn't work in my application. I'm not sure if I got a defective unit. I looked at the remote end output with a scope and the signal was incredibly noisy as compared to the input. The bus I was extending was 100 ft of CAT-5 with my I2C bus running at 100 kHz. Clearly within the claimed capability of the device. Simple questions posted on the support forum went unanswered. I didn't pursue this further as a solution so I can't speak to what the problem was. I solved the problem by putting an inexpensive processor (Arduino UNO) near the location where the I2C sensor needed to be and wrote code to return the result via a serial port. I think this was ultimately a better solution anyway. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B013Z6MTRC | | Additional Features | Ergonomic | | Brand | Mayhew Labs | | Connectivity Technology | ethernet | | Controller Type | Button Control | | Customer Reviews | 4.1 out of 5 stars 4 Reviews | | Manufacturer | Mayhew Labs | | Mfr Part Number | I2C & Power Extender End Node | | Special Feature | Ergonomic | | UPC | 635040975041 | ## Product Details - **Brand:** Mayhew Labs - **Special Feature:** Ergonomic - **Connectivity Technology:** ethernet - **Controller Type:** Button Control - **UPC:** 635040975041 ## Images ![I2C & Power Extender End Node - 2 Pack - Image 1](https://m.media-amazon.com/images/I/41I3Ykgf3IL.jpg) ![I2C & Power Extender End Node - 2 Pack - Image 2](https://m.media-amazon.com/images/I/51mYO9EtQGL.jpg) ![I2C & Power Extender End Node - 2 Pack - Image 3](https://m.media-amazon.com/images/I/41yxg3C8YQL.jpg) ![I2C & Power Extender End Node - 2 Pack - Image 4](https://m.media-amazon.com/images/I/41IT9QBmAQL.jpg) ![I2C & Power Extender End Node - 2 Pack - Image 5](https://m.media-amazon.com/images/I/51tGVsWtPAL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good option for use of remote I2C devices *by D***1 on November 5, 2016* The parts arrived as promised and worked perfect when installed.
