Hi,
I'm currently using a Teensy 3.6 with a NRF24L01+ module. For my prototype I'm running the radio module from the 3.3V pin on the Teensy. When I power the system via a USB cable and secondly with a 4.5 V battery connected to the Teensy Vcc pin the system works fine, and I'm able to send data between the transmitter and receiver to test the system.
I'm trying to develop the system to perform some prolonged tests, and need to power the transmitter system with a 5V power supply. I have a 1.5A 5V linear voltage regulator, and when trialed I cannot get any data to send from the transmitter circuit (nothing else has changed). I am getting 5 V at the Teensy board, and 3.3V at the radio module. To test that the system was working I also wired up an external LED to blink without the radio module being used and this worked correctly, so the Teensy is powering up.
I'm slightly confused why this isn't working, I've checked through my wiring and this is correct with all the grounds connected. The system is currently wired on a breadboard for debugging.
I was wondering if anyone else in the community has come across this problem, and whether changing the power supply to a switching regulator would help in this instance, as I'm stepping down from 24V to 5V. Unfortunately I cannot use batteries for this particular application.
Only I cannot quite figure why the current setup isn't working and any ideas would be much appreciated
Many thanks
