Bluetooth DIP Module voltage

Hi All,

Anyone have experience on how much voltage the Bluetooth DIP Module can tolerate? I know its rated at 3.3v and I am wondering if I dare give it 5v or will it burn up?

What is the typical % of voltage margin for a device like this?

Thanks,

Serge

Anything more than 5% off the specified voltage would be pushing it. 5v is definitely too much. If you’re using 5v I would suggest the [BlueSMiRF. It’s a bit more expensive, but it has a voltage regulator and level translators on board. If you already have the DIP module, you can regulate the power to 3.3v and use some kind of level translator (transistors, a full level-translator chip, or just a current-limiting resistor).](Bluetooth Modem - BlueSMiRF Gold (Old-School) - WRL-00582 - SparkFun Electronics)

Thanks for this information. Do you have any good links to a web resource which would help me calculate the value I need if I were to go with the CLR route?

Thanks,

Serge
