DJ, since im having issues with win8, I decided to pull out my usb to serial adapter. it does 3.3 or 5v. I tried 3.3. I attached according to how labeled on my board. Starting from pin closest to power connector it is RX,TX,GND,V+ I smelled hot resistor after a couple minutes so I unplugged everything and checked the underside of the Bluetooth card. Starting from same reference its labeled VCC,GND,TX,RX.
WORRIED SOMETHING IS FRIED
Your EZ-B is v3 (not 3.1, etc). https://synthiam.com/Tutorials/Diagnostics.aspx
So your bluetooth module has an adapter
Thanks dj, I will check it in the morning. Ive packed it away to take to work,
The rerouting pcb located between the BT and the EZ-B, I actually ended up with that burning up the traces too. I tried removing it and attaching wires from the BT to the EZ-B but ended up with the pads on the BT lifting off the pcb due to heat from my soldering iron.
The way i connected my usb to serial adapter for my omnibot's EZ-B is only connecting signal lines and ground. Saves a lot of trouble
This is true Niek however for devices that require the 5V input rather than just sending and receiving, adding the gnds having to be tied together, it makes that extra V+ line on the connector handy. I actually have this little beauty in my collection however I don't have it hooked to my ez-b. It's going to my arduIMU V3. It should be well capable of connecting with the EZ-B,.
