Spec Detail
1. U8 RTC DS1307 with CR1220 Battery Datasheet
2. U7 TMP102 Temperature Sensor Datasheet
3. U9 24C32 32Kbit EEPROM JP10 Disable Jumper Datasheet
4. U6 MCP4725 12bit Digital-to-Analog Converter , Datasheet
JP11 (AOUT, GND) JP1 Disable Jumper
5. U11 ADS1015 12bit Analog-to-Digital Converter , Datasheet
J7 INPUT (AIN0, AIN1,AIN2,AIN3,GND,3V3) JP12 Disable Jumper
6, J5 (5V, GND,SCL,SDL) I2C output
7. 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)
8. U16 DS9503P 1-Wire ESD protection diode
9. U2 - USB 7 Ports HUB chipset
J1 (JP3) USB HUB upper port signal input from Rs-Pi
10. 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.
11. J11 for RS-Pi V2 GPIO connector (got 4 more GPIO pin)
