Microduino-USBHOST

Microduino-GPRS/GSM module can get Microduino core board connected to the internet and achieve the function of sending and receiving messages when it is just inserted with a SIM card and follows some simple instructions.

Features

  • ESD protection;
  • Capable of being charged by USB, li-ion or other power supply options;
  • Support automatic baud rate detection function;
  • Capable of sending AT instructions and data through the serial port;
  • Small, cheap, stackable and open;
  • Open hardware circuit design and Arduino compatible programming development environment;
  • Uniformed Microduino interface standard and rich peripheral modules, capable of having a fast and flexible connection and extension with other modules and sensors in accord with Microduino interface standard;
  • Easy to be integrated to pegboards with a 2.45-pitch female header connector interface.

Specifications

Adopt SIM800L module to support four-band GSM/GPRS, whose working band is：GSM850, EGSM900, DCS1800 and PCS1900MHz.

  • Electrical characteristics
    • Working voltage：3.4V ~4.4V；
    • The current consumption is 0.7 mA under the Sleep Mode
  • GPRS data
    • The maximum data transmission rate of GPRS is 85.6 kbps;；
    • Build-in TCP/IP protocol；
    • Encoding format：CS-1, CS-2, CS-3 and CS-4；
    • Support Unstructured Supplementary Service Data(USSD)
  • Serial debugging
    • Support standard full-function serial as well as the transmission rate with a range from 1200bps to 115200bps;
    • Support the serial port multiplexing function complying with GSM 07.10 protocol；
  • Two Main Compoments:
    • SIM800L module
Microduino-SIM800L-Pinout
Microduino-SIM800L-Pinout
    • SIM card power and base plant
Microduino-SIM-Pinout
Microduino-SIM-Pinout

Document

Development

You can use GSM library to test, https://github.com/Microduino/Microduino_Tutorials/tree/master/Microduino_Libraries/_03_Microduino_GSM_SIM800L

Note：This library only supports Microduino-core.

Application

Sending short messages through the example program in the library.

Preparation

  • Hardware：Microduino FT232R, Microduino Core, Microduino GSM, USB cable or lithium battery；
  • Software: GSM library, Arduino IDE (version 1.0.3 and higher)；
  • Uncompress the zip folder to libraries of Arduino IDE；
  • Connect the Microduino FT232R and PC using USB cable to download program and monitor the serial port；
  • USB cable or li-ion battery to charge the Microduino GSM module and press the power button for a long time to activate Microduino GSM for about 4 seconds. That the power-on indicator goes on shows a successful start.

Debugging

  • Download the test program:

https://github.com/Microduino/Microduino_Tutorials/commit/25a821ba8894fb02d4b1560c9912450cc353b875

  • Open the test program, you need double check the following parameter:
    • “#define NUM "13667928xxx"”：Need change to the number that receive message.
    • “#define SMS_CEN "13010720xxx"”：Your message center for you own mobile phone number, you can find it in your phone. It isn't the nessary. If hit an issue during send a message, you can try it.
  • Compile the program, select the boardy type "Microduino Core+ (Atmega644P@16M,5V)", download directly:
  • Open the serial monitor, set the baud rate is 9600:
    • Input "t", to send the message "wiki.microduino.cc";
    • Input "d", you can make a call, but can't finish a normal call, because no the speaker and microphone;
    • Input "h", you can submit a HTTP request to get some data from network;
    • Input "s", you can send the sensor data to newtork.
  • 如果你使用Microduino Core调试，你需要用到软串口（TX1，RX1）
  • If you use the Microduino Cort to debug, must use the SoftwareSerail (TX1,RX1)
    • Use the SoftwareSerial library
#include <SoftwareSerial.h>

SoftwareSerial mySerial(2, 3); // RX, TX
    • Change the Serial1 to mySerial, it should be ok。
  • If you use the Microduino CoreUSB to debug, you only need to change the serail to serial 0 (TX0,RX0).

FQA

  • Does this module can be used to make a voice phone? Any voice pin was picked out?
    • This module can’t be made a voice phone, because it doesn’t have pin.
  • Does this module can work with Core+ module?
    • Yes.
  • Does this module can use Arduino GSM library?
    • Yes.
  • Does this module can use to 3G?
    • No, it only supports GPRS and GSM.
  • How to power on this module?
    • There are two methods:
      • Using the USB on attached module to supply the power, the voltage is 5V and the current MUST lager than 1A.
      • Using Li-ion battery on attached module to supply the power, the Li-ion should be 3.7V.

BM module can power on the Core module and other module, such as 10DOF, but don't suggest to power GPRS/GSM module, because it is a big power consumption module.
