Seeeduino Stalker v2

Features

• Arduino compatible, based on Seeeduino
• Design operation temperature -40C to +85C
• Full on board Real Time Clock (RTC) functionality RX8025 with internal crystal oscillator. No battery needed, this RTC is powered to keep time in its off state by a large super capacitor.
• Lithium battery Charging circuit CN3083 with a power input for a Solar panel or other DC power. Recommended input voltage range of 4.6V to 6V, as we have a protect diode in series.
• Micro SD card socket (micro SD card not included)
• I2C Digital Temperature Sensor: Accuracy: 0.5C (-25C to +85C)
• Self isolating I2C when powered off. Normally an Arduino slave on an I2C bus when powered off will short the clock and data signals to ground disabling the entire I2C bus. This circuit will self isolate and allow the other devices to continue communicating.
• user defined LED
• Bee series socket (2*10 pin 2.0mm pitch, same as Xbee) with an additional break out footprint 0.10 inch pitch.
• Can be woken up from a low power sleep state by the RTC at a predefined time.
• ISP socket.
• Power input revers polarity protection diode.
• Cut-able solder jumper.
• UART

Applications

• Autonomous vehicle
• Solar powered weather station
• Data collecting ocean buoy
