Raspberry Pi - 7 USB Hub & SPI 23s17 x1 16 GPIO Board

  

 Raspberry Pi  7 Ports USB Hub & SPI 23s17-1 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 yo 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 adapater 

 
 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 portand 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.

                                            Rs-Pi 7 Port USB hub 23x17-1 board  plug-in Raspberry Pi

 

 

    Rs-Pi 7hub 23x17-1  plug in Raspberry Pi  with 16 GPIO LED  "ON"

 

  

 

               The SPI 23s17 can control and detect by pi-face software.     

                   

 

 

our new output test program    23s17-1port-v100.py   display all 16 GPIO status

Spec Detail

1. U15 SPI 23s17 16 GPIO        23s17 ; 23s17 ; 23s17 ; 23s17 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,   then you can plug-in 5V in this port.

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