I hope I am posting this in the right place in the forum…
I am trying to connect a Bluetooth module HC-05 to a microcontroller New NodeMCU V3, and I have the following question:
The pins that the Bluetooth module uses to send/receive work with 3.3V. Can I connect these to the microcontroller’s New NodeMCU pins? I haven’t found New NodeMCU’s specifications anywhere, and I’m afraid I can damage the module or the New NodeMCU microcontroller.
