Hello everyone,
Just received Arduino Mega 2560 which does not have the following components as shown on the photo. What kind of components are missed and where can I order them. Is it dangerous if I'll just put the jumpers(wires) instead of resistors?

I could be resistor array 4x22R i the middle and varistors on both sides. USB D+ and D- is disconnected without it.
In the schematics (here on the web), the resistors are RN2A, RN2B, RN2C, RN2D and the varistors Z1, Z2.

For some reason I can't open your image (not necessarily your fault).

My advise is to send it back.
If you understand an example, use it.
If you don't understand an example, don't use it.
