    My original USB TTL dongle also purchased on Amazon over a year ago was apparently bad from reading reviews of that item. I decided to spend a few extra bucks and get a better version since I do a lot with routers and messing with OpenWRT. Also into Raspberry Pi now so I figured Id get a good one this time. Worked perfectly and I saved my EdgeRouterX last night. Just remember you have to cross the TXD and RXD connections for it to work. Also look on YouTube for tutorials and specifics for your model device.

    There are a lot of serial to usb adapters on the market, but I really like this one and have purchased several of them for use at home and at work. The ability to select several different voltages for the interface using a jumper allows you to use the device in various situations. Very nice physical presentation and easy to configure and use. Highly recommended.

    Sometimes I run into issues where certain adapters just wont communicate properly with a chip Im trying to program. So I ordered this one to attempt to fix an issue I was having programming another chip and this one worked the first time beautifully.

Ideal for programmers, hardware engineers and DIY User.
Compared to other USB to TTL UART adapters, this adapter not only supports 3.3V and 5V logic levels, but also adds support for 1.8V logic levels.

circuits.
