check this module electrodragon nrf module

@Mickey Looks like a nice module, have you tested it?
-
currently Im using this modules:
and the smd nrf version have a range like the normal version. I just saw it and thought I share . anyway going to buy and test a couple...

Interesting stuff. Would have bought a couple of them if it had another voltage regulator more battery friendly. And the authentication chip. Also, with all the talk of bad nrf24 chips, it is probably time to get around to making the radio integrated on the board. But just soldering the nrf24 smd board to the back is obviously so much easier. It's weird that no one has looked into an in-house mysensor pcb for the smd module yet.
@Mickey are you still happy with your SMD nrf24 boards? No issues with range or other weird issues?
Giles did something like that with his Micromesh board (https://hackaday.io/project/2492-micromesh-iot-mesh-network). Did not turn out well apparently.

I saw the hackaday.io project with the smd and also the poor range report but it was after I bought 6 modules and got very disappointed but then I check 6 modules from 2 diffrent chinees marchents and they both gave me an excellent range without caps.
then I put one inside 2 point outlet box and connected 2 5v relays to pro mini raw and the range and signal quality was very poor, then added a cup and the range got back to be as before I attached the relays. so from there on I only buying the smd version and really got to shrink my sensors.
in this outlet I managed to squise a 220vac to 5vdc ,the smd module, 2 relays:

@Mickey Nice, can you show the inside of the box?

@bjornhallberg There are also advantages to leaving the radio on a riser board as it allows us to design smaller PCBs. For example, here is a printout of the IR Blaster board that I am designing with the radio sitting in the location it will be on the final PCB and then adjacent to the PCB for comparison. Notice that using a radio riser allows us to place components under the NRF board that might otherwise be occupied by the radio... In this design, we are using a double-sided PCB with 0603 components because the smaller we can make the PCBs, the less expensive they will be for users... That said, I think @tbowmo @hek are mulling on-board radio over too
-
Anyone try these out? They look pretty ideal.
-
@Mickey Did you end up buying any? Thoughts? Thanks!
-
No I decide that price is to high. in this price I can buy 2 pro and 2 nrf smd version.
