I doubt many people may have the same precise needs as me, but I figured I&rsquo;d document it, in case anyone comes across a use one day.

This was more than 20 years ago.&nbsp; There are far more capable devices available today.</p><img src="https://community.element14.com/aggbug?PostID=29858&AppID=84&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/products/raspberry-pi/raspberrypi_projects/b/blog/posts/e-z-usb-to-i2c-adapter-and-uart-bridgeTue, 09 Jun 2026 19:30:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:fcae1edb-68a0-45fd-a631-fcf74bed2167DAB0<p>Nice post.</p> <p>This device could be very useful.</p><img src="https://community.element14.com/aggbug?PostID=29858&AppID=84&AppType=Weblog&ContentType=0" width="1" height="1">
