DownloadATMEL ATMega1280 based powerful, multifunctional, reliable, expandable and extremely flexible hardware platform for home and industrial processes automation, robotic toys, security systems, education and enjoyment.
Features
- Includes Atmel ATmega1280 chip with 128k internal flash program memory clocked by 14.7456 MHz crystal
- Power supply: 3.3 Vdc, dual independent stabilized power sources (7-14 V unregulated input as main source, 0.8-14 V input as backup or battery source), interrupt driven power failure detection
- Four independent input lines for alarm sensors (PIR sensors, etc) and one line for tamper detection
- Two 10A 240 VAC relay outputs
- Four hardware serial interfaces for communication with GSM/Ethernet/Bluethooth/Zigbee/GPS modules, JPEG CMOS cameras etc. (One serial port is used by onboard USB-to-Serial FT232BL chip to simplify device configuration, flashing and debugging procedures but USB functionality may be disabled by a jumper so there will be four serial ports at your service)
- Dedicated I2C real time clock chip
- Dedicated I2C thermometer/thermostat chip
- Standard AVR ISP 10-pin connector for in-circuit flashing
- Standard JTAG 10-pin connector for in-circuit debugging
- USB connection via serial port emulation, Win/Linux driver support
- MicroSD slot for storing pictures, sounds etc
- I2C connector for interfacing with tilt/accelerometer/motion etc sensors
- Interface for 2×16 3.3V LCD display, backlight fading out feature
- Two buttons for toggling modes
- Three LEDs (green, red and blue) to indicate states, the first one is used for USB traffic indication, the last two could be programmed at designer discretion
- PWM driven interface to external speaker
- Four interfaces to external servo motors
- Pre-flashed bootloader allows to program the unit via USB, no need in external AVR ISP programmer
- Open source firmware unlocks literally unlimited potential of this unit
- Two extension connectors with 10 and 6 I/O lines
