Scorpion Nano PRODUCT UPDATE.

THE SCORPION NANO IS MORE RELIABLE– BUT THE WIRING HAS CHANGED.  KEEP UP WITH THE CHANGES.

the Basic Scorpion Nano Wiring Diagrams, Old and New.  INCLUDes Receiver Connections:

Robot Power has just changed their Scorpion Nano.  In a few isolated cases, providing power and ground from two sources to the receiver can create issues.  To solve this, ROBOT POWER HAS CHANGED FROM THREE wires on each connection to a single wire on the connection NEAREST THE LARGE BLACK IC.  IF YOU ARE EQUATING TO A RC PLANE CONTROLLER, THIS IS THE THROTTLE CHANNEL.  THE CONNECTOR NEAREST THE SWITCH WOULD BE THE STEERING CHANNEL ON A PLANE. 

one connection has three wires, power, ground, and signal.  These are typically red, black, and white, or brown, red, and orange.  The other connection ONLY has the signal connection, colored yellow.  See below for more information.

Note:  Robot Power has also added glue as a strain relief on the receiver connections.  this does not affect the operation of the UNIT, only protects the SOLDER ON THE wiring connections TO THE BOARD from breakage.

Identifying Receiver Connections:

  1. Identify the connectors on the Scorpion Nano so that you are clear which is channel 1 and channel 2.  See the diagram.
    • The Channel 1 wires and connector are the ones that are close to the larger, square, black integrated circuit
    • The Channel 2 wires and connector are the ones that are closest to the small switch in the center of the board near one edge.

Other configurations are possible, depending on how the motors are wired, which connector is plugged into which channel, and your programming setup. We offer this as a known good configuration.

Robot Power’s changeS TO the Scorpion Nano MAKE THE BOARD MORE RELIABLE.  HOWEVER, IT DOES MEAN THAT THE WAY THE BOARD IS CONNECTED TO THE RECEIVER IS SLIGHTLY DIFFERENT.  DON’T BE THROWN BY THIS CHANGE;  IT’S REALLY QUITE STRAIGHTFORWARD.

 

In a few isolated cases, providing power and ground from two sources to the receiver can create issues.  To solve this, ROBOT POWER HAS CHANGED FROM THREE wires on each connection to a single wire on the second connection.  ThE ONLY DIFFERENCE IS THAT, INSTEAD OF PLUGGING IN A 3 WIRE CONNECTOR, YOU ONLY PLUG IN A SINGLE WIRE CONNECTOR.

Note that in this configuration, the single yellow wire plugs into CHANNEL 1.  You can make different configurations work, depending on how you have the wires attached to the motor, your programming set up, etc.  We know this configuration works with the programming setup illustrated on the scorpion wiring blog entry here.
