Seeeduino Stalker V3.1

As long as you're going to make an outdoor data-logging application, no matter your level of familiarity with this feature rich Wireless Sensor Network Node, this is the board for you!

The main purpose of this series is to create an X-bee carrier board so that users can make outdoor applications more conveniently. Ever since debut launch in 2009, Seeeders have been continuously collecting feedback from users to aid with the upgrading of the board. Currently, there are 6 versions that were launched in the past 7 years. This summer Seeedstudio is releasing their most updated member of the Seeeduino stalker family--Seeeduino Stalker V3.1.

Seeeduino Stalker V3.1 is not just a simple update of V3.0.The main takeaway you'll find about the board is it's impressively low power consumption. In sleep mode, the output current of the entire board will be as low as 100uA. The main reason for this is that in the V3.1, when MCU is put into sleep mode, all other power supplements, including the Bee area port, 3.3v port and the VCC can be cut off manually, so that power can ultimately be saved.

Other Changes

• There is a toggle switch added to X-bee area, which allows you to select either the hardware serial port or software serial port base on what need.

• Seeedstudio also added 2 toggle switches on the RTC circuitry corresponding 2 INT pin of MCU, so that users can easily choose which INT pin they want to connect to the RTC INT port, to then activate the MCU.

• Just like every other new release, Seeedstudio fixed a few bugs.

Features

• Arduino compatible, based on Seeeduino

• RTC powered by button cell only

• 2 toggle switch on RTC circuitry

• Serial interface with DTR for auto reset during programming when operating in standalone mode.(For programming, UartSBee must be bought separately)

• Bee series socket - 2*10 pin 2.0mm pitch (which will mate with - one at a time - any of the wireless modules: X-Bee, Bluetooth-Bee, GPS-Bee or RF-Bee.)

• 1 toggle switch on Bee socket

• Micro-SD card socket

• I2C Pin header (operation voltage is selectable: 5.0V or 3.3V)

• User defined LED

NOTE

• Please set D0,D1 as input before going into sleep mode

• Please turn on the power before using Bee, grove port, 3.3v and 5v port

• The IO Ports work in 0~3.3v level only
