iControlPad2 $62
Building a carputer or autonomous robot with a Raspberry Pi is cool but once you need to connect a keyboard, mouse, and other peripherals it starts to look a little clunky. The iControPad 2 is a vast improvement over lugging an old Dell keyboard and mouse around just to interact with a Raspberry Pi. It’s a small, battery-powered Bluetooth-enabled keyboard, gamepad, and mouse that is barely larger than a Raspberry Pi. Perfect for building a portable MAME machine, carputer, or just to have a really, really tiny keyboard around.
