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 100mW RFM22B 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)

*Note: The setup and use of Open LRS requires computer programming skills and basic Arduino experience. This is not a "plug and play" system. See the attached document under the "Files" tab for resources on programming info, firmware downloads and more.
*Note: Open LRS uses 3.3v FTDI support, DO NOT use a 5V serial / AVRISP adapter or damage will occur.
*Note: This is not an original Arduino brand product.
- Blade Count:
Great deal for a transmitter. I replaced the module with a 1W transceiver chip and have considerably better range. Really make sure to use a 3.3V FTDI programmer. Not the programmer they recommend, it doesn't work.Excellent price and plug and playWorks great. Needs to be modded to send telemetry back to my taranis, but its an easy mod (just add a signal inverter). Would have been nice for this to be included with a jumper on the board.I'm a fan open Open-anything, this module does what I need it to do and there is plenty of forum coverage on how to program this module as well as a lot of config examples.with antennas that includes, telemetry enabled, and optimal configuration of frequency hopping, from 30 meters lose packets and 50 meters to failsafe.Excellent product, highly configurable with many options (if you mount the openlrs firmware) . I'm using it to control servos using Arduino through ppm signal.Excellent product, highly configurable with many options (if you mount the openlrs firmware) .

Look for the Google Chrome app. Cut out a slot in the back of the module to access the FTDI header. One cool feature is the beacon. Once set up, it will transmit the 5 'Close encounter of the third kind' tones when you cut the transmitter. You use a cheap walkie talkie to pick the signal. The 5 tones are sent at different power levels to help you localise your model.https://www.youtube.com/watch?v=AkSYLHrE6gU
Test with turnigy 9xr and orange open lrs. 2 km so far with good rssi the newest firmware and better antennas.Careful with this, it seems to be decent, but you need to flash it yourself or it won't work a tiny bit. Also, the picture shows an SMA female connector on the module (with an SMA male on the antenna I reckon), but mine came with an RP-SMA MALE on the module, of course with an SMA male on the antenna. Rather stupid.
Then again, wouldn't really trust the stock antenna on this anyway, it's better to just go ahead and upgrade to a 1/2 wave antenna (HK sells the RMilec one, I ordered one of those to see how it goes).
Can't beat the price, and it'll do the job once you make the necessary modifications. Do keep these things in mind though!
