I used 3 module and all of them is reset. what can be the problem?

- Tue Oct 20, 2015 7:27 am #31825 Hi, power dipping is the most common reason for resets. It looks like you have a good setup but just double check the connections. Do you have CH_PD connected to Vcc ether directly or via a resistor?
