    Description

    Maybe you are very familiar with the seeeduino stalker series, or maybe you are totally new to this feature rich Wireless Sensor Network Node. No matter what situation you are in, if you are going to make an outdoor data-logging application, you will find that Seeeduino Stalker is the best board.

    The main purpose of creating this series is to create an X-bee carrier board so that users can make outdoor application more conveniently. Ever since the first version be released in 2009, Seeeders have been continuously collecting feedback from users and kept upgrading the board. there are 6 versions ever existed during the past 7 years, this summer we are excited to release the 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 surprise you'll find about the board is impressively low power consumption, in sleep mode, the output current of the whole board will be as low as 100uA,the mian reason for this progress is that in V3.1, when MCU is in sleep mode, all other power supplement, including Bee area port, 3.3v port, VCC can be cut off manually, so that power can really 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 you want to connect.

    • We also added 2 toggle switch on RTC circuitry corresponding 2 INT pin of MCU, so that users can easily choose which INT pin to be connected with RTC INT port then activate MCU.

    • Just like every other revises, we fixed a few bugs.


    SPECIFICATIONS

    • Arduino compatible, based on Seeeduino

    • MCU: ATmega328P

    • 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

    • ŸMicro-SD card socket

    • ŸI2C Pin header (operation voltage is selectable: 5.0V or 3.3V)

    • ŸUser defined LED

    • ŸCurrent in sleep mode:<100 uA

    • ŸSize of PCB:86.1mm x 60mm


    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

    I have connected 2x DHT22 and 1x DS18B20 to 3.3V with the obligatory 4k7 between data line and 3.3V. But it seems that power collapse and there is no serial communication. In case I replace the 3.3V power source with a normal pin set as output and high all is working fine. So I think something is wrong with the 3.3V switchable power.

    Hello, seems that it need a bit more in-depth debugging that we can do via comments.
    Please contact techsupport@seeed.cc with your set up, the code you’re using, and any errors you might be getting.
    Thanks.

    In detail my wiring:

    1. DHT22 [1]
    Vcc   -> 3.3V
    GND   -> GND
    Sense -> D6
    + 4k7 between 3.3V and D6

    2. DHT22 [2]
    Vcc   -> 3.3V
    GND   -> GND
    Sense -> D7
    + 4k7 between 3.3V and D7

    3. DS18B20
    Vcc   -> 3.3V
    GND   -> GND
    Sense -> D8
    + 4k7 between 3.3V and D8


    I'm using a"raW"DHT so ther is no additiona PCB wit additional components. The DS18B20 is a waterproof version with a cable.


    This is my test sketch, serious!


    // counter
    int i=0;

    void setup() {
      // serial communication
      Serial.begin(9600);

      // in version 3.1 of the Seeeduino Stalker a power switching pin
      // for 3.3 V and the GPRS pins / bee socket was introduced:
      // set pin 9 high to switch power on
      pinMode(9, OUTPUT);
      digitalWrite(9, HIGH);
      delay(500);
    }

    void loop() {
      Serial.print("Test");
      Serial.println(i);
      i++;
    }


    With this setup and code I got noting! not serial output at all!!

    In case I connect the sensors Vcc pins not to 3.3V but to D9 (as power(!) source) all is working. So something is wrong with the 3.3V power source or switching power or power and serial port!

    I have tested this with a second Stalker v3.1 board same problem. Oblivious all is working with the v3.0 of the Stalker.

    Hello, Please can you give some exemple code about how to turn on power on grove port and how to setup D0, D1? Thank you

    D9 is controlling the power of Vcc - if you need power, you should make D9 HIGH: digitalWrite(9, HIGH), and don’t forget to pinMode(9, OUTPUT) in the Setup
