NRF24-SHIM (mini-HAT), an interface board for NRF32L01+ radio boards for Raspberry Pi.
This project came to reality when I was looking for a way to connect standard NRF24L01+ module to my Pi. I had found many tutorials explaining how to connect NRF24 modules to Pi but no ready made board or even proper schematics. "Hmm... DIY!" I've told myself and here we are.
Raspberry Pi 40-pin NRF24-SHIM mini-HAT.
Preview:
Features:
- locked Pi headers
- locked NRF24 headers
- double set of Pi headers (for inside and outside mount)
- SPI0/SPI1 bus selection
- CE/IRQ selection
- can be used as SHIM (no headers) or HAT (with headers)
Pins Configuration:
| NRF24 Pin | Option 1 | Option 2 |
|---|---|---|
| CE | GPIO22* | GPIO25 |
| CSN | GPIO8* | GPIO18 |
| SCK | GPIO11* | GPIO21 |
| MOSI | GPIO10* | GPIO20 |
| MISO | GPIO9* | GPIO19 |
| IRQ | GPIO23 | GPIO24 |
*) the pin is connected by default.
CAM files are available.
