Arduino nano + logic level shifter + 3.3v PSU+RFM69HW?
-
I have tried alot of times to build a functioning RFM69HW gateway and failed. Can anyone tell me how to correctly wire a logic level shifter to the rfm radio.
What I have done previously is to connect the arduino side to the HV side and the LV to the RFM69 radio. 3.3v , 5v and two GND from the arduino goes to the 3.3v/5v/GND on the logic level shifter.
3.3v/GND on the radio is connected to a 5v--> 3.3v psu powered from usb.
Is this correct?
