The all new OrangeRX Open LRS TX Module is an open source transmitter module that can be programmed to use your choice of protocol and any channel in the 400~460MHz range. It is a fully user-customizable RF transmitter system. It can even be programmed to utilize extra features such as telemetry when used with the OrangeRX OpenLRS Rx module.
The OrangeRX Open LRS TX Module a very versatile unit perfect for your custom projects.
It utilizes a 1000mW RF unit and Atmega328 processor with Arduino Bootloader allowing you to upload pre-written codes or write your own to suit your transmitter needs.
The default code utilizes 3 channel frequency hopping. If you would like to use a different protocol, you can write your own hopping codes or simply download one of the many pre-written OpenLRS code sets already available.
• 3.3v FTDI support for easy programming (DO NOT use 5V serial / AVRISP adapters)
• Serial Port for firmware upload and telemetry application
• I2C port for sensor applications (Wii Motion Plus based Headtracker)
• 16Mhz Atmega328 processor with Arduino Pro Mini compatible bootloader.
• LM2937 3.3v voltage regulator
• U.F.L connector between PCB and antenna
• Buzzer for audible information
• 1000mW output, frequency hopping capability and hundreds of features
Compatibility: 5-pin JR compatible module-based transmitters
Voltage input: 6.8~12VDC
Range: Full range system

This was the best emitter that could even be used as receiver using the Ultimate LRS software. Compatible with Ardupilot telemetry, it provides an awesome range.
Considering that you don't even need the hkpilot telemetry set when you use these, I can say the value for the price is amazing. Please HK we need restock! Check the ultimate LRS website to see the improvments that you should make to this module to get the best range possible.Best LRS option considering its price in the market so adviced.good for mods with my apm. nicethese have crap range out of the box but all you need is to turn the stock antenna into a half wave whip all you need is a wire and antenna tube start at 350mm and slowly cut it back checking rrsi dont cut shorter than 310mm use a quarter wave on rx i left the rx in my house and walked half way across town without lossing signal i didnt go to the max range ill never fly that far awayWARNING! I bought 3 of these orange lrs modules and in ALL of them the ground plane on the pigtail was broken. If you are getting 200-300m range probably yours is broken too. And here is the real fun part: You probably burned the TX at this point(practically run the module without antenna)
I strongly recommend running a continuity test on the pigtail before ever turning the module on. Also if you have an soderin iron put dab of soder on SMA's pins. That was botced one of my modules too. Seriously messed up QCAfter a couple of months I have been trying to get my OpenLRS Orange RX 1W TX to work correctly. It's still not, at least not as good as you'd expect it to work.
No problem with the flashing process (OpenLRSNG) and binding, so far everything was fine. However, even with decent antennae (SR771 on TX and Sander on RX), the maximum range I could achieve was 1.8Km, beyond that the RX went into failsafe. Not even close to what you can get with FrSky system (I have achieved 2.5Kms easily).
I also had a defective pintail that was replaced by an SMA cable directly soldered onto the board. At full power, the transmitting power is ~420mW which is supposed to give ~50Km range with good antennae.
A friend of mine had the same setup and didn't manage to get it to work correctly having a range even worse than mine. We decided to go back to FrSky which works way beyond what you can expect of a 2.4G system.Works excellent with my Turnigy 9x (ER9X firmware). Flashed with the newest version of openLRSng it provides lots of cool features, such as Spectrum Analyzer or telemetry (orange RX module can transmit data back to TX module which beeps on lost packets). Overall, OrangeRx Open LRS is one of the best TX modules you can buy for your JR or 9x transmitter.There is no information regarding whether the unit requires to be flashed with the firmware in order for the unit to work. So, I tried to bind it to a OrangeRx open lrs 9 channel receiver. It never made the five beeps and never bound. After making 20 attempts to get the firmware updated (it would never connect), using the Orange RX firmware update kit, I noticed the unit LED's were dead and I am assuming the unit is now dead. Not worth spending $20 to ship it back to China only to have to wait for several months to get another one back, assuming HK will actually warranty it.
Waste of money.
Incorrect part sent to me. One month on, still waiting for part to be authorised and delivered.Great little thing here. I have a FrSky DF combo which I'm very satisfied with, but aiming for longer range brought me to this and adding also the fun setting it up, choosing and flashing firmwares, the possibility to flash it as a receiver and have 1W telemetry in both ways, makes this module unbeatable.
