Seeeduino Stalker is a feature rich Arduino compatible Wireless Sensor Network node. It's modular structure and onboard peripherals makes it convenient to log and time stamp sensor data on a periodic basis. The Seeeduino Stalker is a good candidate for all your tracking, monitoring and control projects.

Features

  • Arduino compatible, based on Seeeduino
  • Onboard microcontroller: ATmega328P
  • Onboard Real Time Clock chip with a supercap as a backup power source
  • Serial interface with DTR for auto reset during programming when operating in standalone mode. (For programming, UartSBee must be bought separately)
  • microSD card socket
  • I2C Pin header (operation voltage is selectable: 5.0V or 3.3V)
  • User defined switch and LED
  • Bee series socket - 2*10 pin 2.0mm pitch (which will mate with - one at a time - any of the wireless modules: XBee, BluetoothBee, GPSBee or RFBee.)

Please note that The IO Ports work in 0~3.3v level only.

Handy Hints

I brought some of these boards and they are great,

Please note that the IO on this board is 0 - 3.3V level only, not 0 - 5V level.

When connecting to the computer, ensure you have the board selected as Arduino Pro/Pro mini 8Mhz, 3.3V with ATmega 328
(If you don't, the example code serial monitor output will not work properly)

Hopefully this helps as i must admit it took me a little while to work out what i was doing wrong as most of these details are in the fine print.

Best of luck :)

5 volt v 3.3 volts

A little problem that I discovered with the 2.1 version ...

If you run the board off a 5 volt supply - e.g. USB. Then run it off 3.3 volt supply, the RTC capacitor is still charged with 5 volts, communication with the RTC fails due to inappropriate I2C voltage levels. Discharge the capacitor and all is good ...
