NRF24L01 Arduino用ワイヤレストランシーバーモジュールSMAアンテナMCU Geekcreit-公式Arduinoボードで動作する製品
Ok
The description of the product is confusing, once it says NFR24L01, for the second time it says NRF24L01+. On the picture the NRF24L01+ is displayed. But I have received the old version NRF24L01 which is not compatible with mysensors.org and therefore useless for me.
Great product for the value
Not yet received. take so long
Goods in accordance witn the order, good appearance and functioning
OTTIMO
Delivered, works well.
I purchased this item to add it to a Devo 7E RC Transmitter with Deviation firmware. While it worked ok at the beginning I started to lose signal on my quadcopter (V262) at 40 meters. Later I found out this module does not have PA (power amplifier) so max output at 2.4G is 10 mW... one with PA has 150mW and 300 meters range. Might work ok in other aplications. Visit RC forums - V262 Thread- review of jameschen072, for more info.
I bought a few to built a network with Arduino's. They work perfect although I made the mistake of not seeing that these are missing the PA. So the distance between them cannot be very large. When used on an Arduino you have to take care that the NRF needs 3.3volt and the Arduino models for 5volt can only deliver this while connected to USB.
The NRF24 is a good little radio module for you projects. relaible communication with the minimum stuffing around. I recommend buying the interface boards with on board regulator when considering these. I would also recommend getting the improved version of this unit the +PA+LNA. There are good tutorials on the unit available that will make their use even easier. Use the RF24 library.
