it unable to transmit when powering from 3v3 of arduino uno(can receive packets only)..when from 5v its get very hot..any suggestions???
when from 5v its get very hot..any suggestions???
1) Buy a new one as you will probably have fried that one. 2) Use a voltage regulator to reduce the 5V to 3V3. Don't forget the capacitors.
An LD1117 voltage regulator should be suitable.
Hi, Strongly suggest a separate regulator and bypass capacitors.
THIS MODULE really works for many people...
