Here's me running it via a USB serial device supplying 3.3V. The specs say it will run from 3.3 - 5V. Default baud rate is 9600 and amazingly these devices have the 1Hz PPM output which used to only be available on the more expensive modules.
With a little bit of tinkering I've now got it displaying on an OLED display. Makes a nice clock for the shack.
Amazing that a device costing $4 can receive satellites.
