Hello, I got this board - https://www.dfrobot.com/product-844.html, Romeo V2 controller. I want to connect a nrf24l01 + pa + lna module.
Using this schematic of the board (http://image.dfrobot.com/image/data/DFR ... %20sch.pdf), I have found that:
-Miso-digital pin 11
-Mosi-digital pin 10
-Sck-digital pin 9
Correct me If I am wrong please. I can not find CE, CSN, IRQ pins. Please help me.
After doing some review, you can connect CE, CSN, and IRQ to any digital pin on the board. These outputs can be used in the general Arduino GPIO setup. You can take a look at the following link for your information: https://www.rhydolabz.com/wiki/?p=15956 . Although IRQ is not mentioned, you can simply connect it to a digital pin and read from it to see when the value is set to low to see if a interrupt was triggered.
