Abstract
The following is how to wiring the components together. Please use this pinout diagram for reference. To find out more details about the parts please view the Bill of Materials page of the wiki.
RFID RC522
To connect the RC522 module to SPI use the following schematic.
| Board pin name | Board pin | Physical RPi pin | RPi pin name |
|---|---|---|---|
| SDA | 1 | 24 | GPIO8, CE0 |
| SCK | 2 | 23 | GPIO11, SCKL |
| MOSI | 3 | 19 | GPIO10, MOSI |
| MISO | 4 | 21 | GPIO9, MISO |
| IRQ | 29 | GPIO5 | |
| GND | 6 | 6, 9, 20, 25 | Ground |
| RST | 31 | GPIO6 | |
| 3.3V | 8 | 1,17 | 3V3 |

To connect the epd using SPI using the following schematic:
| Board pin name | Board pin | RPi pin name |
|---|---|---|
| VCC | 1 | 3v3 |
| GND | 6 | GND |
| DIN | 19 | GPIO10, MOSI |
| CLK | 11 | GPIO11, SCKL |
| CS | 24 | GPIO8, CE0 |
| DC | 22 | GPIO25 |
| RST | 11 | GPIO17 |
| BUSY | 18 | GPIO24 |
Servo
To connect the servo, note that the data pin must be able to support PWM.
| Board pin name | Board pin | RPi pin name |
|---|---|---|
| VCC | 2 | 5v |
| GND | 6 | GND |
| Data | 35 | GPIO19 |
Buzzer
To connect the buzzer you can use any data pin, in this case we used GPIO 12.
| Board pin name | Board pin | RPi pin name |
|---|---|---|
| IO | 32 | GPIO12 |
| GND | 30 | GND |
