Yes it's 3.3V on the "1W" module, and we can also cut a trace and apply 5V via another regulator.

This said the range is already much improved over the 100 mW version, so I didn't need such a modification for now.

Regarding the 3.3V on communication pins, I checked directly with the manufacturer.

Dear Benoit,

Thanks for your email.

Would you kindly share more information about your company and the application?
How about the forecast?

May I know when and where you bought the samples from?

RFM23BP is a module combined with RFM23B and power amplifier.
5V power is for amplifier.
So operated power of chip is 3.3V, and the power of the ports which communicate with MCU is also 3.3V.
It means the voltage of the communication pins is 3.3V.

We have many new products with good performance and low price.
Enclosed with the products list for your reference.

Best Regards,
Candy Liu

This is fantastic. I hope that instructions and/or firmware available soon. I am looking to minimize radios and would love to get the datalink via the same radio as my flight radio. Thank you for working on this hack.

software has been available forever now, nothings new really
you just use openlrsng and load the tx as rx for the firmware selection

What's new is the support for the 1W HK TX in the plane. openlrsng does not support this configuration.

ahh ok I see, you can do rx as tx but not in reverse

Exactly, and as the HK 1W TX is very cheap, you can have a full 1W RC + telemetry system for $ 56.

So flipflap, when are we going to see your firmware?

Why not just flash the TX as an RX in the Gui>


So why would flashing a 1 watt Tx as an RX in the GUI not work like it was simply a 1 watt RX?

Just curious?

Well it's quite common to do the opposite, flashing a RX as TX. But flashing the 1W HK TX as a RX is not supported by openlrsng, as far as I know :

In addition I made several changes to have a reliable and fast telemetry link, which fully supports 19200 bauds end to end speed from a 125000 bauds RF link.

How can you connect a PC to the TX module to feed APM telemetry data to mission planner? Bluetooth would be sweet.

In my particular setup, I fly from inside the car, so the rain, frost, fog or snow is not an issue. the antenna is on the roof, connected via a 2 meter coax.

still waiting on my tx from hobbykink. It has been almost thirty days. When they get here I am eager to try this setup. Thank you for the development work on this.

Don't we need flipflap to give us some firmware to make this work?..

I better order another tx from Hobbyking so I'm ready to go too.

Can you please update the pictures for the Tx module connection to APM or pixhawk? Thank you

I finally received my modules in this week and am hoping to play with them this weekend.
