Raspberry Pi - spi 23s17 & GPIO 8 Switch Board


Raspberry Pi - spi 23s17 & GPIO 8 Switch Board





This board use   RS-Pi  pin 11,12,13,15,16,18,22,7 as GPIO 0 to GPIO7 to control Switch 1 to 8 ,

 You still got i2c , and SPI , TX, Rx signal available from your Raspberry Pi,

WiringPi  support 8 GPIO switch 




  * spi 23s17 provide 16 extra GPIO

*  support Rs-Pi V2 P5 got extra 4 GPIO (28,29,30,31)

*  2 extra 12c input for sensors  (5V or 3v3) (5V port with Level converter)

*   J7   GND,5V, SDA,SCL     J8   GND,3V3, SDA,SCL

 Red power-good V+ LED

 1.6A PolySwitch Fuse for V+ input protect.

 Pi_Scratch control demo

1.Setting GPIO (17,18,27,22,23,24,25,4) as input  control Switch 1 to 8 , 

2. broadcast  "Update" 

3. in Sensing --> Slider , you will see the GPIO 17,18,27,22,23,24,25,4 in the list



Detect GPIO (17,18,27,22,23,24,25,4) switch status

Press GPIO17 input switch  output to GPIO28 LED
