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.
- Built- charge management IC (Input 5V)
- LED status display: 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
- Single button: Press button long time – turn on. After startup, short press- transmitting, long press-turn off
- 18B20 temperature sensor: IC precision 0.0625 degrees, passes the temperature of inside/outside the machine and the board in real time
- The buzzer (beep): Switch and transmitter, there beep prompt, convenient to determine the state and blind transfer machines
- TF deck: Internal device flash memory allow you to store your position history with second by second resolution
Integrated Hardware: GPS module, antenna, MCU SCM (Single-Chip Micro), VHF transceiver modules, built-in lithium battery, charger IC, temperature sensor, TF card, buzzer, wireless Bluetooth module:
1. GPS Module
SIRF4 GPS module, high sensitivity, fast positioning, less drifting, stable power.
2. GPS Antenna
18mm * 18mm active GPS antenna, built-in LNA amplification, Star Search, locate quickly.
3. AVR SCM
AVR Mega 64 SCM, stable and reliable.
4. VHF Module (1W)
The latest 1W VHF transceiver modules, tiny one, high stability for all types of wireless data transmission.
5. VHF Antenna
VHF antennas are individually matched to send plants to ensure that the standing wave emission and emission efficiency.
6. 3,300mAh battery
Quality lithium batteries by IMAX B6 0.6A charge and discharge. Standby 28-36 hours with the emission interval of about 20 seconds. Or it will work up to 90 hours when on the low-power mode or a wider interval.
7. Built-in 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 for charging. Green is the GPS indicator: Flashing indicates that no location. If it’s on, it means successful positioning.
9. Single Button (power switch and manual transmit)
Turn on / off – Hold the button.
Manual Transmit – After startup, short press it.
10. 18B20 Temperature Sensor (-40C ~ +99C)
IC precision at 0.0625 degree.
It delivers the temperature inside the machine in real time.
(Need to extract the temperature sensor out if to measure the outside temperature)
11. Buzzer ( beep )
A starting-up and transmission reminder, easy to know the working status.
12. TF Deck (to record coordinates )
The following supports 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)
13. Bluetooth 2.0 Module (for Mobile Phone Connectivity )
