Another post reminded me of this question I've been meaning to ask.
The underside of the EZB has traces near the bluetooth connector that seem to me like a user selectable voltage to the connector. My question is: Can I break the trace for the +5V jumper pad and solder the jumper pad for +3.3V? Also would this change the logic levels on that connector or only change the V+ pin to 3.3V?
The EZ-B will accept logic to a maximum of 5 volts. Any voltage greater than 0 volts is considered ON. Any voltage referencing GND (zero volts) is OFF.
The pad can be cut on the EZ-B to power +3.3v to the communication header. Additionally, you can get 3.3v from the side header.
