internal 4 Ports USB HUB &

Multi-function i2c A/D D/A 1-Wire Board for Raspberry Pi

(RTC, Temperature Sensor, D/A, A/D, EEPROM, MCP23008, DS2482-100)

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 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.

9. J13 Mini USB 5V input for USB HUB, you don't need plug 5V , the HUB already use 5V from Raspberry Pi,

if your use USB device need more power, then you can plug-in 5V in this port.

Adafruit Occidentalis v0.2 image support the
TMP102 , RTC DS1307 , ADS1015 and 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.

Full Support by our Pi_Scratch software can be very easy control by Scratch

Pi_Scratch detail Scratch driver software

(1) i2c address 48 TMP102 temperature sensor test

after broadcast "Update" in Sensing --> Slider , you will see the Temp in the list

(2) i2c address 68 DS1307 RTC detect & demo

after broadcast "Update" in Sensing --> Slider , you will see the RTC in the list

"Year, Month, Day, Date, Hour, Minutes, seconds"

RTC information from Raspberry Pi i2c RTC module

if you can't detect RTC function in Scratch

you have echo ds1307 in /etc/rc.local

in 0x68 address display "UU"

send broadcast"rtc" then broadcast"update"

after broadcast "Update" in Sensing --> Slider , you will see the RTC in the list

"Year, Month, Day, Date, Hour, Minutes, seconds"

(3) i2c address 20 23008 8 GPIO test

use command 8pin+"address"+a"bit (1 to 8)"

8pin+"address"+ a"10001000" --> 8bit mode

8pin20a5 --> output to address 20 bit 5

or use "8pin20a10010011" --> 8bit address 20 from 8 to 1 "10010011"

(4) i2c address 49 adc ads1015 4 channel input test

i2c adc ads1015 12bit Analog-to-Digital Converter

after broadcast "Update" in Sensing --> Slider , you will see the ADC1, ADC2,ADC3, ADC4 in the list

(1)adc1 input & output to 23008 8 bit GPIO bit 1

if adc1 < 2 23008 bit 1 LED "ON" 8pin20a1

(2) adc2 input & output to 23008 8 bit GPIO bit 7

if adc2 < 2 23008 bit 7 LED "ON" 8pin20a7

(5) EEPROM i2c address 50 24c32 read/write

command "EEP" + start address x, start address y + " message"

--> EEP 0x00 0x00 pridopia eeprom test

The System will open a new screen for EEPROM editor , need waiting about 10 seconds
