Geeetech developed 3D WiFi Module, with the only aim of enabling all the 3D printing hobbyists to control their printer wirelessly. Our rigorous tests confirm that 3D WiFi Module is broadly compatible with many different kinds of 3D printers on the market. As long as the USB to serial chip of your printer belongs to one of these three ones (CH340, FT232 and PL2303) and is controlled by G.code instructions, our 3D WiFi Module can upgrade your machine as Wi-Fi enabled and make it comparable to other prohibitively expensive Wi-Fi connected 3D printers.
