Hi,

today arrived the Olimex EKG/EMG-Shield.

I do the steps for setup the shield to the Olimexino328:
- Jumper on Olimexino to 5V
- Jumper on the Shield to 5V, too
- REF_E close
- D9 close

when i connect the Olimexino with the Shield together on my notebook, the IC2 going more hotter than the other pcb.

can somebody help me ? what is going wrong ? Cable to measure EMG/EKG is not connected.

many thanks,
chris
