# NRF24-SHIM project
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.
## NRF24-SHIM
Raspberry Pi 40-pin **NRF24-SHIM** mini-HAT.
Preview:
[Schematics in PDF format](doc/NRF24-SHIM.pdf)
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.
## NRF24-mini-SHIM
Raspberry Pi **NTF32-mini-SHIM** micro-HAT.
Preview:
[Schematics in PDF format](doc/NRF24-mini-SHIM.pdf)
Features:
- locked Pi headers
- locked NRF24 headers
- CE/IRQ selection
- very small size
- fits on 26- and 40-pin Pi headers
Pins Configuration:
|NRF24 Pin |Option 1 |Option 2 |
|----------|---------|---------|
|CE |GPIO22\* |GPIO25 |
|CSN |GPIO8\* | |
|SCK |GPIO11\* | |
|MOSI |GPIO10\* | |
|MISO |GPIO9\* | |
|IRQ |GPIO23 |GPIO24 |
\*) the pin is connected by default.
CAM files are available.
## NRF24-zero-SHIM
Raspberry Pi zero 40-pin **NRF24-zero-SHIM** mini-HAT.
Preview:
[Schematics in PDF format](doc/NRF24-zero-SHIM.pdf)
Features:
- locked Pi headers
- locked NRF24 headers
- Pi zero board style
- SPI0/SPI1 bus selection
- CE/IRQ selection
- double NRF24 configuration possible
- can be used as SHIM (no headers) or HAT (with headers)
Pins Configuration:
|NRF24 Pin |Option 1 |Option 2 |Option 3 |Option 4 |Option 5 |
|----------|---------|---------|---------|---------|---------|
|P0 CE |GPIO22\* |GPIO25 |GPIO27 | | |
|P0 CSN |GPIO8\* |GPIO7 |GPIO18 |GPIO17 |GPIO16 |
|P0 SCK |GPIO11\* |GPIO21 | | | |
|P0 MOSI |GPIO10\* |GPIO20 | | | |
|P0 MISO |GPIO9\* |GPIO19 | | | |
|P0 IRQ |GPIO23 |GPIO24 | | | |
|P1 CE |GPIO22 |GPIO25\* |GPIO27 | | |
|P1 CSN |GPIO8 |GPIO7 |GPIO18\* |GPIO17 |GPIO16 |
|P1 SCK |GPIO11 |GPIO21\* | | | |
|P1 MOSI |GPIO10 |GPIO20\* | | | |
|P1 MISO |GPIO9 |GPIO19\* | | | |
|P1 IRQ |GPIO23 |GPIO24 | | | |
\*) the pin is connected by default.
CAM files are available.
## BOM
Bill Of Materials is currently available only for LCSC Electronic Components Distributor, which is probably cheapest anyway.
### LCSC BOM
|Designator |Part/Value |Package/Footprint |LCSC # |
|--------------------------------|-----------|------------------|-------|
|C1, C3\* |Cap. 100nF |0402 |C1525 |
|C2, C4\* |Cap. 1uF |0603 |C15849 |
|R1, R2, R3, R4, R5, R6, R7, R8\*|Res. 10K |0402 |C25744 |
\*) These passive components are optional but it's recommended to install them.
