💬 Easy-Peasy Amplified MySensors Serial Gateway

@Yveaux good point. Wemos D1 mini uses a ME6211 ldo which is rated for 500mA (600mA absolute maximum). If I remember correctly, the nrf24 with pa/lna needs a maximum of 115mA and the esp8266 itself 160mA. So there should be plenty of margin.

I hope all the clones will use the same LDO, or equivalent then ;-)

Lets hope people stick to the originals since they are not that expensive

very simple :)
I agree with yveaux though, always good to have some optional footprints for decoupling in case. No idea if there are some. Also, putting electronics above antenna (of esp8266) is not very recommended, but this should work.

This does not use the genuine NRF24L01+ by the looks of it.
The wording is clever, but the imported parts list does not include Norway and the device is only 'based on' and imported chip from Norway. Nowhere does it say it incorporates this chip and if you look at the RF spec, it can operate higher than the NRF spec sheet for the real chip.....
-
I don't know anything more than you do. However, you could substitute a different amplified nRF24L01+ module if you prefer. I can say that it seems to work alright at 250kbps and 1mbps. 2mbps is possibly problematic, though in my limited testing the cause of that may be unrelated.
-
I had a chance to test the module more thoroughly, and it appears to work just fine at 2mbps also. So, as of this moment, everything seems good, and I'm not aware of any problems. :)

The newer E01-2G4M27D has more powerful transmit and more sensitive receive capability:
