The goal of this launch campaign is to test functions of all subsystems during the drastic high-speed flight scenario. In the meantime, the flight data can be help the 2nd stage rocket design of the future dual-stage sounding rocket and the validation of launch site safety measure. HTTP-3S Sounding Rocket System Architecture. MicroRidge manufactures a variety of serial interface devices. We had a need for a fast, effective and easy-to-use serial test communications program. We developed ComTestSerial to meet that need, and are offering it free of charge to anyone who has a need for a test program to help them understand the output of their serial device.

Introduction
This GPRS/GSM/GPS Shield based on Ai-think A7 module, which is a newest GSM GRPS+GPS Quad-Band module. This Shield integrated these necessary functions for you to build an outdoor or mobile application, such as mobile tracker, cargo monitoring. The Shield is controlled via AT commands, and fully compatible with Arduino/Maduino.
Model: OAS0000A7
Serial 3s Test
Features
- Support the GSM / GPRS four bands, including 850,900,1800,1900MHZ
- Support GPS and AGPS
- Support digital audio and analog audio support for HR, FR, EFR, AMR speech coding
- Support GPRS data traffic, the maximum data rate, download 85.6Kbps, upload 42.8Kbps
- Support SMS text messaging
- Support voice calls
Interface Function
Connectors:
- Headset jack-This is a 'standard' TRRS 3.5mm phone headset jack with stereo earphone and mono microphone. Any 'iPhone' or 'Android' compatible (but not iPhone original) should work.
- uFL GSM connector-This is the GSM Antenna connector, an antenna is required to use the SIM808 shield!
- uFL GPS connector-This is the GPS Antenna connector, an antenna is required if you want to get GPS readings!
- SIM Connector:A 2G Mini SIM card is required to use the module. You can buy it in any cell phone shop. It must be a 2G GSM card.
LEDs
- PWR –Power light
- Status – Power on status. Lit when the Cell module is booted and running
POWER_KEY
- PON Power on the A7.
- POFF Power off the A7.
Pins usage on Arduino
- D0 - Used if you select hardware serial port to communicate with A7
- D1 - Used if you select hardware serial port to communicate with A7
- D7 - Used if you select software serial port to communicate with A7
- D8 - Used if you select software serial port to communicate with A7
- D2 - Used for software control the LOW POWER model of the A7
- D3 - Used for software control the Power ON of the A7
- D9 - Used for software control the Power OFF of the A7
Usage
On its own, this shield can't do anything. It requires a microcontroller like an Arduino to drive it! You will also need some required accessories to make SIM808 shield work.
SIM Card! A 2G Mini SIM card is required to do anything on the cellular network. US AT&T no longer sells 2G SIMs and will shut off their 2G network, so for American customers we recommend any T-Mobile or reseller (TING, SIMPLE mobile, etc) that uses the T-Mobile network.
Assembly
1.Attaching Antennas:GSM antenna is required to use the Cellular module. If you want to use GPS as well, a passive GPS antenna is also required.
2.SIM Card:
Insert a mini SIM card(GPS does work without a SIM)
3.Connect the headset to the headset jack.(when you make a call you may need to use it)
4.Plug to Arduino or Maduino, connect the USB to the PC.
Power on the A7 shield by the PON( sometime you can control it by the software control ( Arduino D9 PIN))
Load Demo
Print the GPS data with serial port
Open up File: A7_Get_GPS_Info.ino and upload to your Arduino wired up to the module.
Once uploaded to your Arduino, open up the serial console at 9600 baud speed to show the test result:
