Olimex ATMega128 header board

Hello, I’m a newbie to electronics. so please bear with me.

I just got Olimex ATmega128 header board. I looked at the schematic and I’m puzzed where to start :slight_smile: I just want to connect it with power and download simple program using the AVR-USB-JTAG and AVR studio.

I see the power pin labeled power (+). Is this is the one that connects to the source 5v? In the schematic, I see many pins connected to 5v but not sure if I need to connect all the pins labeled 5v to the source power or just the single power 5v pin (labeled +).

Also, in AVR studio do i select JTAGICE or JTAGICE-mkii with the AVR-USB-JTAG?

Thanks a million.

JTAG ICE choice - Which do you have? JTAGICE is the old original or there are some clones. MK-II is newer and there are also some Asian clones.

Power and ground connections - the board has a regulator so it’s intended to be used with a 9VDC or so wall transformer. Or you remove the EPWR jumper and provide 5VDC regulated. Be careful that this 5V is clean. You can connect that 5V to the proper pin on the EPWR jumper.
