Seeeduino Stalker (ATmega328)

Arduino-compatible wireless sensor node based on ATmega328, with onboard RTC, CR2032 backup battery, microSD socket, dual-voltage (5 V/3.3 V) I2C hub, and an XBee-form-factor socket. Functionally identical to the ATmega168 variant but with double the flash (32 kB vs 16 kB).
