Hello.
I am experiencing a similar problem and I would appreciate some help.
I have recently purchased a black widow (328 chip) and some rainbowduinos (328 chip).
In some forums, I read that using these two devices with this chip is incompatible. Is this right?
If I was supplying the rainbowduino board with a 6v power from the JST 2 pin connection and did not connect the GND, VCC wires would this be correct?
Thanks.
