I have some of those too. I was getting good results with those as a base and the standard modules as nodes, and figured that these smaller ones would work well for making nodes smaller. And the seller said that code is all they have

Ended up sending me this rar file with c code... its not a datasheet but it might be helpful.

Yea its worth a shot. If all else fails I haven't confirmed that I received it yet so I can still file a dispute

Yea i might try to get a datasheet or something out of the seller. These seem to be the same thing, just different pin layout:

a lot of listings for these have popped up since I got mine, and each one has orders, so I'd expect to see some more people with these modules in the near future

After some more research, I'm thinking this is a completely different chip. No websites list the nrf24lo1+ chip as available in anything other than qfn, which the epoxy blob chips I have are definitely not. Also there are a lot less support components when compared to other nrf24l01+ boards. So I'm not sure what to do from here. How do I find out what chip this is if it is indeed a different chip?

Look at the pingpair_pl example. It uses ack payloads on one pipe address

I bought one lot of these:
http://www.aliexpress.com/item/Free-shipping-10pcs-lot-NRF24L01-wireless-data-transmission-module-NRF24L01-wireless-module/1996222121.html

Thinking that they would work great for small wireless projects. I assumed that they would work exactly like my other standard nrf24l01+ boards, but they won't work at all. They are recognized by the RF24 library as a plus variant, so it can read registers on the chip, but all the values in the other registers are different and neither transmitting nor receiving are working. Did I get fakes? or maybe another chip entirely?

Any help is appreciated

8  Using Arduino / LEDs and Multiplexing / Large LED Matrrix transfer protocol on: February 25, 2014, 07:10:42 am
I am looking to build a large RGB LED matrix composed of several 16x16 panels. Each panel will have an onboard controller and will multiplex with 3 TLC5940s. I have the basic hardware layout, but what would be the best way to transfer all the data between the main controller and the panels? I was thinking of a wired protocol but now I'm considering switching to Artnet so computer control is easier. Any ideas?

And at some point it is a promise of that price as soon as I click the buy button...
10  Using Arduino / LEDs and Multiplexing / Re: Cheap WS2811 LEDs on: September 03, 2013, 01:05:04 pm
I'd definitely post something about them not honoring posted price. Don't think it'll matter or make a difference....but I'd do it anyway.

Yeah! Wreck their feedback because they made a genuine mistake then refused to let you rip them off.


I agree to a point, but if they dont lose something then what motivates them to be more careful next time?

Well crap
12  Using Arduino / LEDs and Multiplexing / Re: Cheap WS2811 LEDs on: September 02, 2013, 02:20:15 pm
Yea I just noticed the page went offline. I guess we'll see if the seller cancels the order or not
13  Using Arduino / LEDs and Multiplexing / Re: Cheap WS2811 LEDs on: September 02, 2013, 12:40:18 pm
Yea I got 10 lots just cause why not. We'll see what happens. I might have just scored 1000 leds for $6.10

So I just found this..

I would look at ShiftPWM
