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
