Hi !

Any side effect or possible circuit damage if I ground the IRQ ?

I use this module with a ItsyBitsy from Adafruit, the pin out is perfectlly aligned but the ground :

Want to know if can ground the IRQ to simplify the connection.

Thanks for support

IRQ is active low, which means when it’s not active, it’s high. Grounding that pin would be a short circuit and could damage the IRQ pin or possibly other parts of the nRF24L01+ chip.

My advice would be to leave it disconnected if you’re not using it.
