Raspberry Pi - I2C 23017 x2 - 32 GPIO Board

   

  

                                                      

                                                  32 GPIO output with 32 Blue LED

 

                                                      Can work with our Rs-Pi-USB Hub Board

 

 

                                                                  i2c  detect  status

   20  -> MCP23008        48  -> tmp102      50  -> 24c32       60    ->  MCP4725     68 -> RTC DS1307

   21 , 22 -> 23017 x2

 

 

                                         use 23017-21.py  set each bit to be High or Low

 

   our new output test program     23017-2port-s-v103.py   display all 32 GPIO status
