Seeeduino Stalker is an extensive Wireless Sensor Network node, with native data logging features and considered modular structure. It could be conveniently used as sensor hub or integrated data collector for monitoring, tracking and etc.
Features:
Arduino compatible, based on Seeeduino
Native RTC, On board CR2032 battery holder
Native micro SD card socket
Easy stackable I2C pin header
Dual voltage (5V/3.3V) I2C hub
Standalone and shield mode
User defined button and LED
B” series socket (2*10 pin 2.0mm pitch, same as Xbee)
Interrupt evoking ready
Serial interface with DTR for auto reset during programming
A newbie question: how do you connect your Stalker to USB? I've wired a FTDI/USB of Sparkfun to the stalker's FTDI bus (tx->rx, rx->tx: is it ok?), but when loading a sketch, one LED is on, an other is blinking, Sparkfun's txLED blinking, arduino console says "uploading", but nothing else happens!
Where could be the problem? Should I choose another board from arduino's menu? Which one? Using Arduino21.
