Title: Lora vcc regulator
Post by: garfius on Jun 23, 2019, 06:50 pm
Hi, i started creating LoRa devices using arduino nano and sx1278 modules and https://github.com/sandeepmistry/arduino-LoRa .

I realized there are serious problems when i use a separated 3.3v voltage regulator.

Everything works perfect while i use the 3.3v output from arduino (ch340 output)

But problems come when i use an ams1117 3.3v regulator instead, stops receiving at the moment i transmit.

Any idea how to solve this?
