My final Gateway version

[TheoL]

My production Gateway is still on a breadboard with a normal NRF24L01+ radio - so not the long range. After 11 years it's time to get rid of that breadboard setup- as it's collecting dust - and make a final PCB for it, so that I can put it in a decent housing. Also a good moment to upgrade from MySensors 2.0.0 to the latest release as I haven't upgraded that Gateway for years.

My plan is to power the gateway from the barrel jack on the Arduino UNO and I also want to replace that normal NRF24L01 with a PAN LNA version. Now I know that extending the range consumes a lot of power. That's why I wanna power the Arduino from the power jack as it can handle 2 Amps. And then use a buck converter that grabs it's power from the VIN pin on the Arduino, to lower the voltage to 3.3V for the radio.

Well that is the plan at least. The official documentation says that you can provide power through the barrel and use the USB.

Here's the schematic for my Uno shield
:

My question is: How much current does the NRF24L01 PAN LNA draw when set to RF24_PA_HIGH?

For now it remains Work In Progress xd

11.3mA according to the datasheet

But 13.5mA when in receive mode.

@mfalkvidd Than I'll order a first prototype if this version. I might even swap the buck converter for an AMS11173V. I always thought it would draw much more current when sending.
