AVRT5 is developed on the basis of the above aprs AVRTT-AVRT4 equipment, the main function is to transmit APRS data integration. Built-in GPS antenna and module + VHF radio transceiver module to TNC codec comprehensive plan. When it power on it can be decoded to work with the standard orientation can be issued after verification of aprs data. It’s compatible with common business APRS equipment and various aprsDIGI repeat and IGATE, it’s a real APRS machine including transmitting and receiving.

Feature:

1.    GPS module

• SIRF4module, high sensitivity, fast positioning, stable power.

2.    GPS antenna

18mm x 18mm active GPS antenna, built-in LNA amplification, Star Search, locate quickly.

3.    AVR SCM

The AVR SCM (Model mega 64), stable and reliable.

4.    VHF Module (1W)

The latest 1W VHF transceiver modules, small size, high stability for all types of wireless data transmission.

5.    HF antenna

VHF antennas are individually matched to send plants to ensure that the standing wave emission and emission efficiency.

6.    3,000 mAh battery

Quality lithium batteries by IMAX B6 0.6A charge and discharge, both are in 2900 - around 3300 mAh. Boot continuous emission interval of about 20 seconds to work 24-36 hours. If the low-power or extend the transmission interval can work continuously for more than 84 hours.

7.    Built- charge management IC (Input 5V)

Built-in lithium red power management IC, avoid battery overshoot and over-discharge, caring protect the battery. Charge current <400mA, operating voltage is lower than 3.4V, automatic low -voltage protection shutdown.

8.    LED status display ( charging and transceiver LCD)

Dual LED display, red is charging indicator, when charging it’s red, full extinguished or dimmed. Green is the GPS indicator: Flashing indicates that no location. If it’s on it means success positioning.

9.    Single button (switches and transmitting)

Press button long time – turn on. After startup, short press- transmitting, long press-turn off

10. 18B20 temperature sensor (-40C ~ +99C)

Temperature sensors; IC precision 0.0625 degrees, passes the temperature of inside/outside the machine and the board in real time. (Need to measure the outside temperature can lead)

11. The buzzer ( beep )

Switch and transmitter, there beep prompt, convenient to determine the state and blind transfer machines.

12. TF deck (record coordinate )

Internal device flash memory allow you to store your position history with second by second resolution. The following support 4G TF card, FAT16 or FAT32 partition format, the file name is automatically named according to the time saved in KML format. For example: at 18:20 on December 10, 2013 to start work positioning. File name : 12101820.KML ( May Day midnight, Greenwich Mean Time ). You can simply read stored position history via USB and export them back to NMEA sentences which can be visualized on-line in most internet map services.

13. The wireless Bluetooth 2.0 module (Connecting phone )

Built-in Bluetooth module, the rate of 9600bps. Firstly it can real-time output aprs decoded signal. Secondly Android phones can be connected to input signalsKISS model TNCand control T5's transmitting. Specific functions can see the APP aprsdroid. Third, you can use Android phones serial commands to configure settings VHF call sign and frequency module.

For example: Set call sign:  AT + CALL = BG6QBV7 ​Set frequency: AT + FREQ = 144.6400 ​Set the buzzer:  AT + BEEP = 1 ON AT + BEEP = 0 OFF
