Hi Photron,
After having removed the Wifi extension, I have only a masterbrick and the colour bricklet, nothing else. As an aside, I can't find a case for the colour bricklet in the shop? I am using the case meant for the i/r temp. bricklet; this works okay somewhat, except I now don't have a case for the i/r bricklet, which I disconnected to trouble shoot.
Cheers
Karl
