New Opensource LRS Coming

Posted by Melih Karakelle on November 12, 2010 at 4:49am
Hi Guys,

I just finished the test of our new opensource long range system modules.
This modules 3th generation and i guess i should design 4th generation before publishing them.

r0010338.jpg


I'm using RFM22B radio modules and ATMEGA328P chips on Rx and Tx.
Rx modules including 8 channel servo ports and RS232 for telemetry uplink

Tx modules including PPM-Input for analog servo control and RS232 for Computer based controls and Telemetry downlink.


System range will be around 4-5km.

Firmware Upgradeable over RS232.


Ground tests was unbelievable, it's working around 500 meters into the city (after 20+ concrete building)

I will share the flight test results, sources and schematics soon.


If you have any idea about design and inputs, please share with me before 4th generation's production..

Thanks for reading

Melih

    Any news on this front? Really interested...

    Thanks for your reply Melih. I wasn't necessarily concerned with size, but more with will this work with a 2.4ghz radio controller (like my Turnigy 9X)? (I am a noob to RC, apologies)

     

    If we can get a casing similar to JR/Futuba modules so it can fit in the Turnigy 9X controller, we will have a controller with open source firmware and a nice long range open source module. :)

    @Ivan

     

    No, first 3 version was only for my personal tests. I2m designing v4 for publishing. It's not including an LCD, you can use your computer for telemetrey ;)

    Melih,

     

    Will v3 boards also be available in your shop? I don't need no LCD screen for telemetry when I have a big screen on my laptop.

    @Kamu

    Our Tx module smaller than all modules(futaba or jr). you can put it into the old modules.

    That's a great question Kamu. I wonder if these will be a DIY module that is to fit inside the transmiter like the Frysky unit or if it could fit inside a module that we could swap out for our regular 2.4Ghz gear and recievers.  I'd be willing to trash one of my Turnigy modules for a re-fit to be able to swap it out.

    A question regarding controllers.. is it possible to interface the OpenFARC with a controller that can switch out modules? (i.e. the turnigy/imax/flysky 9x) I think they are compatible with JR modules.

    @Danstah,

    Rx and TX boards same on v3 boards. Because both side using transceiver modules and all boards Tx+Rx ;)
    But i'm changing the design for v4, and Rx module including RSSI and SerialPPM outputs. Tx board have a buzzer and less pinouts.
    I'm designing a telemetry LCD screen and some sensors now and waiting for sample parts for tests, then i will order the PCBs.

    Do you have any pictures of the TX setup. All the pics i see are of the RX side
