I bought a BiBoard through RoboticsShop as it saved the delay and cost of arranging the import duties payment when it was delivered to the UK. They have no option for buying the Hat.
The Petoi shop doesn't offer the Hat without the board...
Can anyone advise where I can buy a BiBoard Hat V1.0 separately?
Quick question:
Is your BiBoard a V0_1? If so, it lacks the 3 sets of header pins required to mate with the 3 sets of header receivers on the Hat Extension. Here is a link to the underside of a BiBoard V0_1:

Note the header holes (no pins) in the upper left, upper right and lower right.
The BiBoard V0_2 has header pins there. With a bit of simple soldering, you can add these header pins to a BiBoard V0_1.
