Arduino Nano 33 BLE and SIM800L EVB Connection

Official Hardware Nano Family Nano 33 BLE

Hey,

I'm trying to configure a SIM800L EVB module to work with my Arduino Nano 33 BLE. I would like to use it to access the internet (juste make HTTP calls to private API).

I can't manage to find any solution to my problem anywhere because it seems like the Arduino Nano 33 BLE is not that used by the community.

I wired it like that but there's no light coming from any LED of the SIM800L EVB module:

5V -> +5V directly on the Arduino (which I've activated already, working for other modules)
GND -> GND directly on the Arduino (right next to +5V pin)
VDD
SIM_TXD -> D3 pin on the Arduino
SIM_RXD -> D2 pin on the Arduino
GND
RST

VDD GDN (second one) and RST are not connected to anything but from what I've seen it doesn't seems so be an issue.

Is there something I'm doing bad? Am I not delivering enough power to the SIM800L EVB module? In this situation any help, advice or idea could be good, I'm clueless right now.

Thanks!

GSM modules, like the SIM800L EVB module, require too much current (>1A), so you'd need to come up with a separate power solution.
