Doing other things besides GPS

[Nehuix]

Hi, I'm working on a project ya involves and Arduino Nano, temperature measurement (LM35) and geolocation (Neo 6m) and LoRa transmitting (sx1278). It seems that when I connect both LoRa and GPS modules to the external source (3.3V) it stops working. Is it because it doesn't supply enough current? PD: I connected the gps to the Nano's 3.3v pin and it works
