UNO's 3.3V output can only supply 50mA.
|
||
|
|
In addition, the output current capacity of UNO-compatible devices is smaller than that of official products.
|
||
|
|
__So nRF24L01 may not work normally when supplied from the on-board 3v3__.
|
||
|
|
nRF24L01+PA+LNA(nRF24L01+RFX24C01) needs 115mA.

You will need to power it from the 5V pin using a regulator.

These pins are 5V Tolerant and can accept up to 5.25V.

These pins can be changed in the sketch.
