Anyone have any idea how the power supply is connected to the Nervo Board? I’m lost.
The power supply is connected to the Nervo Board via the yellow XT60 connector.
It is wise to add, between the XT60 and the power supply, a main switch for safety shutdown. The switch can be placed in the side back location.
Is the XT60 connector attached to the Nervo Board by soldering at the port of 5/6V?
Yes it is.
There is a picture showing it in the tutorial.
Dear Gael, in the tutorial it stated that “Soldering the little back connector option 3.3V or 5V to power last analog pins.” in Step 3. If I’m using the same voltage for all servo, do I need to solder this? (I’m not using the 3rd nervo board for the finger sensor as I didn’t build that part)
I am guessing you will use a PIR sensor which requires 5V. The PIR sensor detects human motions, it’s nice to have on the robot.
That means you will solder the 5V to power the last analog pins.
To have all servos working on the same voltage, you need to solder the two main jumpers together.
I wonder do I need to solder the third red dot (As stated in Step 2, the one at the bottom-left in the picture) if same voltage applied?
Yes if you want to give 6V to the PIR.
But note that it’s a 3 point solder, this gives you the choice, you can give the PIR 6V or 5V.
This will give 6V to the PIR:
This will give 5V to the PIR:
