I've managed to order a kepypad for my Raspberry Pi but it has an 8 wire matrix connection. Is there a simple, cheap little converter that I can use to convert the 8 wires to an I2C so I can use the I2C connection on the Pi thus leaving more GPIO pins available for servoes and solenoids? This is the Kepyad I ordered. https://www.ebay.com/itm/174125035463 Rhys Sage
