Looks nice in red

Looks like a neat module indeed.
Never tried these, but yes I guess if the external antenna and the wifi antenna are too close it may leat to some interferences.

Would also need to check that the 3.3V is powerful enough to properly feed the esp and this chip at the same time, I guess it may depends on the antenna plugged to it too.

@fabien Never heard of the "Ebyte NRF24 PA+LNA module", do you have a link for it somewhere?

So far I've been using a few of these with the "regular no name" PA+LNA from Aliexpress and did not have any problems. What are the symptoms you are observing?

Forgot about this guy... Updated the project a little, the PCB now have footprints for both normal and PA+LNA modules.
The old boards are still available on the github repository if needed.

Even with the extra length added to the PCB with the dual footprint, it is overall still smaller than a regular non SMD NRF24L01 module.

Actually was not too bad to update.

I pushed the updated example sketch to github and openhardware, compatible with IRremoteESP8266 v2.0 and up.
I did a quick test here, no errors, and the vacuum cleaner already escaped to the bedroom, so good to go!

As for the board, feel free to share any sketch here or on github.

Short and not perfect answer, they changed everything when they updated the library to >2.0.

For a quick way to test your board etc, you can compile the example sketch by reverting to version 1.2.0

Ideally you may want to upgrade your sketch to be compatible with version 2.0 according to this https://github.com/markszabo/IRremoteESP8266/wiki/Upgrading-to-v2.0

I wanted to do it, but completely forgot about it... Will try to have a look at it tonight, but hopefully you can start testing everything using the old library version.

May also ask what minor modifications you did? Always open to suggestions to improve the board.

@Mynasru unfortunately the only other suitable pin would be D1, SCL.
Wemos do not have enough pins to do gateway + I2C, you will need to switch to a nodeMCU or similar.

Also keep in mind that D2 is a MySensor default for ESP8266, I tried to have it moved when support was added https://github.com/mysensors/MySensors/issues/408#issuecomment-191403862 but without success, meaning you will need to reassign CE in your code.

@bilbolodz Actually a PA+LNA version is on github (untested)
https://github.com/emc2cube/SMDnRF24_adapter/tree/master/PA_LNA

But yes, I did not update the openhardware part yet.

The choice of MOSFET can be tricky. Seems that irlz44n was discontinued so you may need to find one adapted to the voltage and current you want to handle.
In all the cases you need to get a logic MOSFET too, meaning that they are fully open usually around 1 to 3V.

Also I'm sort of confused as it seems to me that L7812CV is a Voltage regulator, not a MOSFET. So if you are actually using that in the MOSFET spot it will definitively not work.

Especially if you are handling high current or voltage I would recommend using one from a reputable source for your MOSFET, I recently switched from mouser / digikey / aliexpress to mostly use http://www.arrow.com as you get free regular shipping, event if you order a couple of components (no affiliation to them whatsoever).

@reinhold I bet it's an IRQ issue:

If you are using version 1.1 of the board, with IRQ support, you need to compile the software on the pi with the --my-rf24-irq-pin=18 option (see Install section on openhardware / github)

By default IRQ is on pin 15 so my bet is that if it's working by following https://www.mysensors.org/build/raspberry you just need to recompile the software with this option and it should work
