To continue my previous post about the RedBear Wifi IOT PHAT, I got carried away with talking about incompatibility with servoblaster. I meant to say that I sent a message to the Redbear team early on regarding the fact that they only supplied the HAT with a standard 40 way socket. So when the unit is attached to the PiZero, there is no access to the i/o pins. I don't know if they changed what they are supplying now, because having no access is exactly what the PiZero is not about
I bought a socket with extended pins from eBay so that I can put a Protoboard or individual wires on the pins sticking up above the IOT PHAT. It looks like this:
The pins sticking up at the top are for connections to a couple of servos and a laser pointer for the latest cat toy in production, once I get round the servoblaster problems.
