Servo connection to grovepi+


#1

is it possible to connect your grove servo to the grovepi?

Hey rob, when we tried it on earlier versions it doesn’t work very well. The Servo draws a lot of power and cuasese the GrovePi to reset the Raspberry Pi and an unexpected restart.

Thanks. I have the gopigo board but it only has a 4 connectors and one servo - it might work for what I’m trying but would like more connections and also be able to run servo and the motors. 2 questions

  1. is there a wall power adapter for the gopigo board - the battery works but for my project I don’t need mobility
  2. can I join/stack the gopigo and grovepi boards onto a single raspberryPI 2?

1). Yes, there’s a wall power source for this: http://www.dexterindustries.com/shop/raspberry-pi-power-supply/ But you should NOT run the motors without batteries in place.

2). There’s not a great way to do this. You can pin them though with some jumper wires.

Hey Rob,

You should be able to use any power supply which is rated for 9V to 12V at 2A to use with the GoPiGo.
2) can I join/stack the gopigo and grovepi boards onto a single raspberryPI 2?
You should be able to connect the GrovePi to the GoPiGo. You can just connect a Grove cable b/w the I2C port on the GrovePi and the I2C port on the GoPiGo and it should work.

Hi John,

I’ve already asked in other thread (http://www.dexterindustries.com/topic/raspberry-pi-python-and-servo/#post-95472), but I need your help/advice in order to manage GrovePi + servos using RPI and programming with Python… if it is possible…

Any advice will be welcome!

Regards,

Miguel Angel
