NEW 12pcs NRF24L01+ 2.4GHz Arduino Wireless RF Transceiver Module...

Item was as described and very reasonable.

So yes they are clone chips. We all know that. If you are using the RF24.h library add this code in setup after radio.begin(); radio.setDataRate(RF24_1MBPS); they should run at 10mbps, but these dont. 5hrs later I figured I would help you guys save time. Almost gave up on yhe whole project after this.

I have a lot of time wasted on these, and I should have known better!! At first, they seemed decent since they worked right away since I was plugged into my arduino via USB but if I disconnected the USB and plugged it in only seconds/minutes later it would stop working and I would have to continually reset my arduino to get it to reinitialize. I purchased voltage regulators and even tried adding a "capacitor" (as many people online suggest) to smooth out power but it made no difference. I thought at this point it was just my arduino sketch so I spent 10+ hours troubleshooting it with the same outcome, so I knew it was the transceiver. After I figured out that work around, it was time to connect a battery up to the arduino to test the range, but the transceiver wouldn't work. I tested 3 different arduino boards, and 7 of these transceivers and all behaved the same. If I plugged the battery through the USB of the arduino board it would work, but not if I plugged it into "vin" or the 2.5mm jack, which would limit me to 5v. Ultimately decided to buy a different brand of NRF240L1 transceiver and what do you know, it worked right away! It's unbelievably frustrating to be out so many hours of my time because of this product, but hopefully I've helped someone who is having the same problem. It's possible this was just a "bad" batch, but either way it's unacceptable in my opinion.

I had great success with these modules using the official circuitpython library on raspberry pi via SPI. The official docs including pinout diagrams and was easy to follow.

these were a great value, and they work really well. the only issue i had was that one of the modules still had a small piece of scrap PCB that wasn't taken off before it shipped. it just slipped through the cracks, and had no effect on the operation of the module. i just snapped the extra off, and everything was fine. i also decided to modify a couple of modules, and changed out the straight pins for right angle pins. sometimes using the right angle pins make it an easier fit.
