  * Piezo+ is the line for bimorph shaking the cantilever in tapping mode
  * Extra is Analog2 channel (depending of hardware you have, you may need to toggle some jumpers/switches to route Analog2 to this pin) to bias the tip with EFM cantilever holder only
  * STM is the channel to route STM current signal in STM mode. It is a "free" line when operating with AFM modes
  * +12 and -12V are always there.\\
