  Hi Renzo;
  
  I’m trying to design a pcb similar to your design. Would you suggest I put a decupling capacitor on the lora e32? how many capacitors should i put. Do you think i should put it in front of arduino nano every? Thanks.

  Hi jordan,
  I must take a look at the PCB, generally, the decoupling capacitor is used to stabilize the voltage regulator.

  Hi Renzo;
  
  I emailed EBAYTE. He said you can use 100nf and 1uf. for your information

  Hi Jordan,
  if you use the regulator from Arduino Nano Every, It already has a 1uF capacitor; otherwise, you must check your PCB to select the correct one. If you connect the E32 directly from USB power, It’s ok.
  
  Bye Renzo
