The parts come from a Lexamrk X6570 all-in-one printer wich goes for around 100$ on eBay. This printer has with a Lexmark N2050 WiFi card running BusyBox. After soldering a few wires to the USB/UART pins on the N2050, [sjMoquin] had a very cheap but highly useful single board computer running Linux. So far neither the USB or WIFI is functional but the hackers [sjMoquin]& [Julia Longtin] are currently working on that. so a fully functional embedded Linux board based on a printer’s WiFi card should be available soon.
