that amount of a full PCB with a Bluetooth wireless transmitter and battery. To upgrade your controller, you simply unscrew it, pop out the original PCB, put in the new one and you're off and running. You can charge up the internal battery with a mico-USB cable and there are even new LED indicators to show you how much charge is left.
