Low cost Neo-6M GPS works well

Ross, VK1UN, tipped me off to these GPS modules available from Aliexpress for AU$4.10. At that price I ordered 2. Here's the ad as it appears at the moment.

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.
