Version 0.9 (2017-05-19) - remove ground plate below touch pads 1 & 2 for better touch sensitivity - moved on&off leds a bit further away from the touch pads so they are not directly below the clear part of the glass - holes to attach a 3D printed plastic diffuser, so the light will be more evenly distributed around the button - changed connectors for serial programming to be more convenient - added 2 extra leds on middle button - improved VCC track to limit interferences
