3. U7 TMP102 Temperature Sensor Datasheet

4. U9 24C32 32Kbit EEPROM JP10 Disable Jumper Datasheet

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

JP11 (AOUT, GND) JP1 Disable Jumper

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

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. U15 DS2482-100 I2C to 1-Wire bridge device

J22 1-wire Port pin 1 – pin4

(5V,GND, OW (1-Wire Data, ESD Protected). RT (1-Wire Return/Ground ,ESC protected)

9. U16 DS9503P 1-Wire ESD protection diode

10. U2 – USB 4 Ports HUB chipset

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

11. 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.

 

10. 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
