Neatly installed in the back of the Turnigy 9X Transmitter

This add-on board was designed for the Flysky 2.4Ghz 9-channel radio transmitter model number FS-TH9B, commonly referred to as the "9x".  It is also sold under various other re-branded model names and numbers, including (but not limited to): Flysky FS-TH9X, Eurgle 2.4Ghz, iMax 9x, and Turnigy 9x.

Please note that there have been two generations of the 9x radio transmitter.  They look the same from the outside, but the internal circuit board is very slightly different.  This is important, as this board will not be compatible with first generation radios without some soldering.  See this page for identifying your radio's generation as well as instructions on using our board with a first generation unit.  The marketing by various stores can be confusing.  For example, Turnigy sells their latest ones as "V2" while Eurgle boasts "third generation"... but the fact is that they are referring to their included firmware, not the hardware.  While any recent purchase *should* be a second generation board, there are reports of people getting first generation hardware even when buying "V2" or similar from the store.  The only way to know for sure what generation you have is to open up the case and look at the circuit board. - Please NOTE: Currently all the TURNIGY 9x Transmitters we sell at Pyramid Models are the latest V2 second generation board

The 9x is an amazing value TX in the r/c aircraft world.  You won't find a radio that costs so little that can do so much!  However, it is not without its limitations.  The primary complaint with the 9x radio is that the stock firmware is quite poor.  Thankfully, some very clever people have written entirely new firmware that makes this cheap radio so powerful and flexible that it does things that units costing several hundreds of Pounds more can't even dream of doing!  This add-on board lets you load that new firmware onto your radio easily... with no solderingno cutting, and no specialized tools or skills are required!  As a bonus, our kit also provides advanced support for the popular  9x LED backlight system.

Built-in Programmer

The primary feature of our board is that it gives you a full-time programmer installed in your radio that allows you to "flash" new improved firmware onto your radio whenever you want, just by plugging it into your PC via a common mini USB cable (not included).  If 

you get one of our programmers, you will have to solder 6 wires onto tiny pads on your radio's circuit board.  While many people have done this successfully, there is a lot that can and does go wrong:  incompatible programmer from other sources on EBay; soldering mistakes damaging the radio; frustrating trial and error; unsightly holes cut into your radio's case to make room for the clunky connector... and then you have to plug and unplug the programmer in each time you want to update the radio! 

This programmer stays in your radio and you simply use a ready available mini-USB cable to connect it to your computer.  No soldering and no cutting whatsoever!  And it is designed specifically for the 9x radio! - remove 4 screws, add the new board and screw back in place, what could be more simpler than this !

Advanced LED Backlight Support

The second feature of our this board is the integrated LED backlight driver, which provides support circuitry for the popular - and inexpensive - LED backlight (not included).  The circuitry adds the ability (once appropriate firmware has been flashed) to turn the backlight on and off by a variety of methods, and also provides full control over brightness.  Without our circuit, the LED backlight is on full time and at full brightness only.  As well as the constant-current driver provides steady power to the backlight over the full life of the battery so the light doesn't get progressively more dim as the battery drains, and it also ensures a longer life from the LEDs.  You can puchase the backlight from  in whiteblue, and green.  The use of the backlight with this board does require a modifications to the backlight and also some soldering is involved for this feature.  As of Revision 2.3, we now include a cable with a connector for making the LED connection even easier.

Some important notes:

  • This programmer gives you the tool to install custom firmware on your 9x radio, but we do not have any involvement with the firmware development itself.  We do not provide the custom firmware with the product, nor is it downloadable from our site, but you can get it freely from the Internet.  There are so many options available now that it wouldn't be fair to try to list them here.  Please visit for all your firmware needs!
  • Similarly, we do not provide the software you will need to make use of the programmer, but again there are options available freely from the Internet.  The software you choose will depend on your type of computer and which Firmware you're going to use.  Generically speaking, any software compatible with a USBasp programmer will work (avrdude, for example).  
  • Installation of the board itself is quite straight forward.  The steps are described on this page.



Revision History

Rev 1:  Green board.  First prototype.  Had primary power issue that had to be resolved to function.  Had backlight power issue that resulted in too much power drawn from radio's CPU .

Rev 2:  White board.  Both Rev 1 issues resolved.  Introduced possibility of radio rebooting when light turned off.  No new features.  Slight efficiency improvement with backlight.  Some layout changes.

Rev 2.1:  White board.  Rev 2 issue resolved.  No new features.  Some layout changes.  Different USB and EL connectors used (not compatible with previous revisions).

Rev 2.2:  White board.  EL backlight panel and circuit discontinued and replaced with support for LED backlight.  Complete layout changes.  Programmer power is now independent of radio power, therefore the radio must be powered on during programming.

Rev 2.3:  White board.  Now includes header and plug/wires for LED connection.  also a Header for use with TelemetrEZ added.

Rev 2.4:  White board.   Shape of board changed to a rectangle.  Board now uses 3 screws and 1 nylon support rather than 4 screws.  Custom ISP programming cable included so the SP board can now be used as a generic USBasp for programming other devices.  The main intent of this feature is to be able to update TelemetrEZ without having to open the case (but it can also be used as a programming interface with any AVR device's standard 10 pin ISP header)
