•        Support the dual interface: I2C interface and Serial interface.
•        The module is a master for I2C bus.
•        Standard 100Kbps and Fast 400Kbps I2C interface.
•        8 Bit Data Port.
•        Data Port pins may be individually selected to be digital input /
output, analog input or PWM output.
•        10 Bit ADC, up to 5 analog inputs
•        On-board the pull up resisters for I2C bus.
•        LED to indicate USB connection.
•        The module is self powered from the USB and can supply up to
50mA at 5V for external circuitry.
•        Small form factor (1.6” x 0.7”).

I2C Multifunction Module
New
" I2C - FLEXEL" is a versatile, general-purpose data acquisition module with I2C interface. The
module is designed as Arduino shield and also can be connected to other microcontrollers with I2C
interface.
The module includes a 16-bit microcontroller and works as co-processor for Arduino or your
microcontroller. The embedded pre-programmed microcontroller provides control for external
peripherals and takes care of communication with I2C bus.   

The module is connected to I2C bus as slave device and supports a simple command structure to
communicate with Arduino or your microcontroller. Only two lines are used to connect the module to
Arduino. All other Arduino inputs / outputs can be used for other tasks.


Key Features

Communicate over standard I2C bus (100 Kbit speed) as slave device
Control two bidirection DC motors with max current 1.2A per motor
 Four high power outputs (control relays, high current LEDs …)
 RGB LEDs dimming with up to 750mA current per channel
 Up to 4 servo motor control
 Four channels 12 Bit Analog to Digital Converter
Support the character LCD16x2 and 20x4 with LCD backlight and contrast setup via software
Infrared (IR) remote control
Support a matrix keypad up to 16 keys (4 rows by 4 columns) or up to 8 buttons
Support a standard keyboard with PS2 interface
Real Time Clock and Calendar (RTCC)
Buzzer control
Socket for EEPROM chip with I2C interface
Small form factor - size 2.0” x 2.1” (51mm x 53mm)
