 Made for people be require the adapter to be as small as possible. Not much wider than the serial port itself. 
 
 ## Powering the device
+### MicroUSB:

+The easiest way to power the device would be to use the Picos micro USB port. Be sure to use a USB power only cable or a wall power adapter otherwise it won't pick up the mouse.
 
+### Power-In Header:

+Both the Phat and Slim PCB's feature an 5 volt power in header. You can use this creatively to power the adapter, even from the PC itself perhaps? Personally I'm connecting it to a wall power supply to give a more secure connection than MicroUSB.
 
+### Other ways:
+There is nothing stopping you from powering the device using a powered OTG cable or a hacked up USB extension lead. The device itself needs about 100 milliamps so as long as you get it that power, it'll run away happily!
