Pmod BT2 is not turning on.



I am working on a project in which i am using Pmod Bt2.
Once i have connected Pmod BT2 with Arduino and give it 5 voltage and ground   then after few minutes Pmod BT2 turn off and Now it's not turning on.
What is the problem with it ?
Is it burn due to 5 voltage or what happened with it?

Hi @Abdul Qayyum,

The RN-42(IC) uses 3.3 logic as shown in the resource center for the Pmod BT2.   Here is the home page for the RN-42 here.

1) On page 48 of the Bluetooth Data Module Command Reference & Advanced Information User’s Guide is states that "When using a 5.0-V DC input, GPIO pins require a voltage divider. A good choice is a 10 KΩ series with 20 K to ground. The GPIO pins are 0 - 3.3 V DC, not 5-V tolerant." 

The Pmod BT2 could have been damaged due to the 5V.

thank you,
