I am working on my own design based on USBizi100 and have noticed that pin 7 on the UEXT is MISO0 also shows as CTS1 on the pinouts of USBizi100 which is also pin 6 of the UEXT yet I see no electrical connection using s meter. This is also the case with pins 10 and 4 and pins 9 and 3 of the UEXT. Is this by design or is there an error in the datasheet for the USBizi100?
Hey Paul, welcome to the forums !
i’ve never checke dthe Mini, and don’t have one, so can’t respond with any real knowledge. But one thing I would say is you should check out the Panda or Panda II schematics too as they’re both USBizi100 chip solutions and might give you the additional info you need.
