• General Pin Out is the standard pin out of a Sensor / Trinket connector.
• Sensor / Trinket's Pin Out is this specific Sensor / Trinket's wiring in relation to the General Pin Out.
• SIGNAL-A / SIGNAL-B are signals that could be digital input, digital output, analog input or analog output. Or special signals such as serial communication (SoftwareSerial, IIC (I2C), etc) or other special signals.
• Not Connected refers to the Pin not being used for this particular Sensor / Trinket.
• Read more about the hub module.

Features
