I’ve been unable to make it work when it is directly plugged on my UNO clone. However it works perfectly when I use the Rx, Tx and Gnd pins from the UART under the Status and NetLight LEDs (as shown in picture). For my project it’s okay, but could be a problem if you want the shield to be stacked. In addition it’s clearly not brand new... but hey, at this price point I can’t complain since it’s working!
