I am experimenting with a Jeenode USB V3 with I2C to a IC. It went good. After a while I want to send a new sketch to the Jeenode and I got the message:
Binary sketch size: 2056 bytes (of a 30720 byte maximum) avrdude: stk500_getsync(): not in sync: resp=0x00 avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51
I have 2 same Jeenode's. If I send the sketch to the other Jeenode send I got no problems. If I use a defferend PC I have the same results.
I think that something went wrong in my electronic circuit. But what? I notished that the red battery led burned somthims. I can't find out when that led goos to light. Is a high Amp. to mutch for the USB from the Jeenode whitout damage my PC?
Is there an other way to findout wats the problem?
Thanks for reply
