Is there any software I need to download for GoPiGo and if so where?
Do you have a GoPiGo 2 or a GoPiGo3 ?
If you have the GoPiGo3 and your own Raspbian SD card, you can use this command:
curl -kL dexterindustries.com/update_gopigo3 | bash
If you have DexterOS, then everything is already included.
Hope this helps,
Cleo
