Raspberry Pi - 7 USB Hub & I2C 23017 x1 16

GPIO Board

  

 Raspberry Pi  7 Ports USB Hub & I2C 23017-1 16 GPIO  Board

 

 size small than Raspberry Pi with Multi-Function

 

  Why Raspberry Pi suggest you need use External USB Hub with power Adapter? 
  because they design use 140mA fuse in each USB port, "140mA", 
  but USB spec need 500mA for each port,
  that's why lots people have power issue for USB port.
  in Rs-pi V2 they remove the Fuse design, and you don't have any protect from Rs-Pi USB

port.     What  you can do ? 

  1. modify Rs-pi Fuse power circuit.  

2. Use external USB Hub with power adapter 

 
 Our RS-Pi internal USB hub with 1.5A polyswitch fuse and use USB signal (D+, D-) from

Rs-pi only, not use power from USB port and use Raspberry Pi 5V from P1 pin2 , so if you

have good quality "more than 1.2A" DC 5V adapter , then you can use our Rs-Pi USB hub

 no problem.  if your device need more power, we also can provide extra 5V input

(J13 mini USB B).   The Rs-Pi V1 board  if you not modify the fuse circuit, you may need

plug in extra Dc 5V from  (J13 mini USB B), for the Rs-Pi V2 no need for this input.

Spec Detail

1. U15 I2C 23017 16 GPIO      

     23017 Datasheet

2.  U2 - USB 7 Ports HUB chipset

     J1 (JP3)  USB HUB upper port signal input from Rs-Pi

3.  J13  Mini USB 5V input for USB Hub, you don't need plug 5V , the USB Hub

    already use 5V  from Raspberry Pi (P1 pin2), if your USB device

   need more  power,  you can plug-in 5V in this port.

4. J11  for RS-Pi V2 GPIO connector (got 4 more GPIO pin)
