5 what does "GROUND 3 PLACES" mean ?

1. Banana Jack is where you put you power in (VCC)
2. "Banana Jack" is a Jack. One for Vcc one for GND.
3. The big capacitor is for smoothing Vcc when the circuit takes a lot of current.
4. Dont know, it is not clear from the picture.
5. you put 3 vias. to connect it to the ground plane.
6. Rogers is a manufacturrer of PCB laminate.

Good luck

THANKS a lot!
