Where to get legit nRF24L01+ modules?
-
@Yveaux Fair enough. I won't rel on that, but did want to mention the observation.
On a relatively side note, I got 4 SMD nRF24 cards from eByte, but can't locate any boards to mount them on! The holes are 1.27mm pitch, so I just ordered some 1.27mm headers.
Has anyone grabbed a board to surface mount solder them at this pitch?@Bogus-Exception said in Where to get legit nRF24L01+ modules?:

Has anyone grabbed a board to surface mount solder them at this pitch?What's the pitch on most other SMD nRF24L01+ modules? Is it also 1.27mm, or something else? I hadn't paid attention.

@NeverDie Great question. Mine look like these from a post earlier in this thread, and they are the first I've seen that didn't have their (breadboard-unfriendly) pinout.

Not sure if it's what you mean, but for prototyping purposes you could solder them to generic 1.27mm proto-board, such as this: https://www.aliexpress.com/item/6-X-8CM-spacing-1-27-universal-board-thickness-1-6mm-sided-HASL-PCB-test-board/32774106087.html?spm=a2g0s.9042311.0.0.eD40xE

I received my Ebyte modules, not a warranty of authenticity but the nrf chip has a square instead of a dot like all the fakes I have been using until now. I have a few standard SMD modules and a PA LNA version, I will try to make some basic range tests soon compared to the SMD clones.
@kalina made these DIP-to-SMD-NRF24L01-adapter, but my need isn't enough quantity to buy the chemicals, pay someone to make a rum of them, or convince my wife that, "We'll sell them and make our money back!" :-[

@Nca78 Not just the module (10 for $15, right?), but the page concept is exactly what I am doing these days. Built in flexibility where it matters!
You've clearly spent a lot of time at my stage of tinkering with this!
Little touches like PA pinout, etc. makes this cake have more icing then cake! :o

@Bogus-Exception
I'm sure the Kalina adapter would be inexpensive if you purchased 3 through OSH PARK because the surface area is small. -
@d00616 I have to ask...
How did you create this image?

The image is created with a medical X-Ray machine.

@NeverDie What I meant was, I don't have anything in 1.27mm, so now I've ordered enough stuff to keep my 2.54 and 2.0 company! :)

@d00616 Yeah, but I mean, that image doesn't show detail, does it? I thought it was thermal/IR when I first saw it-like it was running.
First time I've seen this tried. Has it worked for other electronics? Is that image you posted what is usually expected?
And most importantly, how did you talk your dentist/radiologist into doing it?! :) -
@Bogus-Exception may I ask why are you using spi for bme280 sensor instead of i2c?
@gohan Was this wrong? Is there a readon to change?

With the inability to get signal strength from the nRF24, I'm open to any suggestions to fairly evaluate the boards I've collected. Don't think the wife will let me spring for a spectrum analyzer... :(

Somewhere in the other thread I posted a sketch for automatically counting packet loss percentages. That's the best way that I've been able to think of. Signal strength, bit error rate, and packet loss rate should all be very strongly correlated to one another.

@Nca78 where did you get the ebyte modules? From aliexpress they are charging quite a bit for shipping.

Some news. After playing with NRF5 and the NRF24 protocol.
The red EBYTE modules are fakes.Over the N of NRF is a dot. I have ordered these modules: https://aliexpress.com/item/Wireless-Module-NRF24L01-original-2-4-Ghz-RF-transceiver-SPI/32712174920.html they have an rectangle over the N and responding line an original NRF24L01. Maybe this helps to identify originals.
The difference between both modules is in NoACK attribute handling. Fakes always responding with ACK and sending inverse NoACK attributes. So fakes have problems communicate with original modules.EDIT: This was an issue at the NRF5 side.
