Powered Up AutoID’s

Notes to myself:

AutoID’s:

• Train Motor:
  • pin 5 shorted to 4 (VCC)
  • pin 6 shorted to 3 (GND)
• M Motor:
  • 2k2 between pin 3 (GND) and pin 5
  • pin 6 shorted to 3 (GND)
• Lights (needs confirmation):
  • 2k2 between pin 3 (GND) and pin 5
• Tacho Motor (needs confirmation):
  • 2k2 between pin 3 (GND) and 4 (VCC)
  • 2M2 between pin 3 (GND) and 5
  • 2M2 between pin 3 (GND) and 6
  • 2M2 between pin 4 (VCC) and 5
  • 2M2 between pin 4 (VCC) and 6
• WeDo 2.0 Motion Sensor:
  • 2k2 between pin 3 (GND) and 4 (VCC)
  • 135k between pin 3 (GND) and 5
  • 135k between pin 3 (GND) and 6
  • 135k between pin 4 (VCC) and 5
  • 135k between pin 4 (VCC) and 6
• WeDo 2.0 Tilt Sensor:
  • 2k2 between pin 3 (GND) and 4 (VCC)
  • 135k between pin 3 (GND) and 5
  • 135k between pin 3 (GND) and 6
  • 135k between pin 4 (VCC) and 5
  • 135k between pin 4 (VCC) and 5

On the Tacho Motor the 2.2 MΩ measured between both GND and VCC and pin 5 and pin 6 make me think on a voltage divider but values are high. Also the 2.2 kΩ between GND and VCC puzzles me (other devices don’t have it).

The WeDo 2.0 Motion Sensor also has 2k2 between GND and VCC. Hmm… the same with the WeDo 2.0 Tilt sensor. But not the BOOST Color&Distance Sensor (11k).

The two WeDo 2.0 sensors (Motion and Tilt) have same measured resistance. So the AutoID ought to be completed by the protocol.

Also:

VCC is 3.3V
