Hi, first I would like to know what is the current consumption on one Waspmote Gateway SX1272 module.
I would also need to know how much current the gateway need to work correctly on a Raspberry Pi 3.

Also, what is the maximum gateways I can put on a Raspberry Pi 3 that already has a HDMI monitor attached to it. I would need to put at least 11 gateways if possible (using a USB hub of course).

Basically how much current I need for 11 gateways using a Raspberry Pi 3?
Is it possible to put 11 gateways on a single Raspberry Pi 3 using a USB hub?

Thanks for our help.

Hi iPat16

All the power consumption details of the SX1272 module are here:

The power consumption depends on the way that the module transmit.

We have never connected this device to a Raspberry Pi we don't know if your project is possible, you will need to calculate it and try.

Perfect, thanks for the reply.

Hi iPat16,

You are welcome. Good luck with your project.
