(RTC-DS1307, Temperature Sensor-TMP102, D/A ,A/D ,

EEPROM, MCP23008, FT232RL, ZT3243)

 size small than Raspberry Pi with Multi-Function


Spec Detail


1. U5 MCP23008  J2 (GP0 ~  GP7 ) OUTPUT    &    




R20,R21,R22 (A0,A1,A2) address select      JP12 Disable Jumper    


2. U8 RTC DS1307 with CR1220 Battery   

3. U7 TMP102 Temperature Sensor 

4. U9 24C32  32Kbit  EEPROM    JP10 Disable Jumper 

5. U6 MCP4725 12bit Digital-to-Analog Converter ,   

    JP11 (AOUT, GND)  JP1 Disable Jumper

6. U11 ADS1015 12bit  Analog-to-Digital Converter ,  

   J7 INPUT (AIN0, AIN1,AIN2,AIN3,GND,3V3)       JP12 Disable Jumper

7, J5 (5V, GND,SCL,SDL) J6(3v3,GND,SCL,SDL)  I2C output

8.  U2 - USB 4 Ports HUB chipset

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

9.  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 use USB device need more power,

   then you can plug-in 5V in this port.

10. U10 FT232RL  J4 USB input from PC for USB to RS232 console port, just connect

   a cable  (5pin mini USB-B  to A USB ) then you have this console function. 

      U12 ZT3243 RS232 Transceiver Driver , You can have DB9 full 9pin RS232 output

       from PC or Mac USB cable input or from Rs-Pi HUB Port for input  

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


  Adafruit Occidentalis v0.2 image support the


  TMP102 and RTC DS1307 , ADS1015 , MCP4725


Use this board you can learn how to program use "C" or  "Python" , Will provide sample program for test can download from our web site.

also our Rs-Pi USB Hub board have 5 different Ver, all different function and different price, all with short pin Ver, please send email to us, if you are interesting.
