“Bought this to make an Ender 3D printer wireless using Octoprint. Set up the Pi SD card with the download and make sure it works by connecting it to the Ender usb port. Cut a micro USB plug from a lead with about 75mm of wire and solder to the back of the micro usb socket on the Ender control board using just the D+ and D- take the 5V of the 6 pin programming port pins using some jump plugs. Put the Pi in on top of the control board place insulating tap over the pi board back to stop any chance of shorts and put lid back on. Powered up and works brilliant from octoprint web page.”
