nRF24L01+PA+LNA MAX power

[Fat Fly]

How to connect this module to use max power ? In config i know but voltage from external adapter ?

@Fat-Fly - well, you could use a voltage regulator like LE33ACZ or NRF24L01+ Socket Adapter Board (also found in store). The problem might occur if you connect it through the arduino.

This ? Power from adapter, not from arduino.

@Fat-Fly - think so, I have not tested it myself but as long as you have enough mA on your charger/power and that chip doesnt limit it somehow i think it will work great.

I have used this adapter and it works well.

I try. I bought these from China friends 20 pcs.

I also use this small board for powering the nrf+pa+ln. So far no problems with it!

I need solder power wire to Nano mini usb connector directly? I use for power meter Arduino Nano.

If I remember correctly, then this little board has a nice and strong power regulator for 3.3 V on board. On my repeater node I have connected my 5V usb charger to this little board and I use the 3.3 V output to power directly both the pro mini and the nrf.

If you use the socket on the board to put you nrf in, I would feed the board with a strong 5V source.

Okay. I solder wire from nrf socket power directly to arduino nano mini usb connector power wire.

I connect nrf socket + pin to Nano 5V pin. Working perfect.

Hey.

If i need change nrf tx power in arduino sketch. This is right ?
#define MY_RF24_PA_LEVEL RF24_PA_LOW

Replace LOW with HIGH or MAX for the highest power settings
