Please note that when using your transmitter for several models, you need to use the same type of protocol receivers (DSM2 OR DSMX from any manufacturer) in all the models being controlled by the Tx to avoid having to rebind the module to the receiver selected,

( if it is of a different protocol to the protocol that the module has already been bound with..)


In short, & wherever possible, install the same type of protocol Rx in all models in the Tx memory.



If you require an extended module to antenna lead to suit your transmitter installation, then please search on Ebay for a SMA Female Plug to IPX U.FL Female Pigtail Cable Antenna WiFi Mini PCI


The Lemon Rx® DIY module addresses the need for RC modeler in legacy transmitter conversion. The firmware is specifically designed to restore the original PPM waveform on Lemon Rx or Spektrum receiver. The module accepts 5V to 12V as supply input while accepting PPM signal from 3V to 12V with auto detection on PPM signal polarity. The module accepts high tolerance of PPM signal found in some legacy transmitter while accepting a minimum of 2 channels and up.


Caution before installation

- Avoid static electric by grounding yourself to metallic surface. Metallic surface working table is recommended (such as on top of a laundry).
- Do not interrupt power provided to the module initially. Doing so may damage the RF front-end. Make sure power wiring harness is connected securely before providing power to the module. 
- Install SMT connector to SMA conversion cable to the module as well as antenna prior to power on. Power on without antenna may possibly damages the device.

Antenna connection and Wiring implementation 1
The SMT U.FL connector closest to the center of module should only be used for RF transmission. The optional 3 header pins can be optionally soldered for Ground, V+ and PPM signal in. All these connections are needed for full operation with the on board button for binding and range check. See below diagram.

Wiring implementation 2
Below diagram uses the module pads for direct soldering to suit installation needs. The 3 header pins on implementation 1 can be ignored by using these connections. External bind push button soldering pad can be found here.


Bind procedure and implementation
Bind button on board can be used or externally wired with 2 pads labelled "PB".

- Turn on the transmitter and by pass all the warning messages (if any)
- Wait until the module turns on with red light on and green light flashing
- Release button
- Observe indication. Green light on means binding is completed. Red light flashing indicates bind fails. Turn off the transmitter and resume the whole binding procedure if bind fails.

Range check
During normal operation (green light on), press and hold the button puts the module in range check mode (red light on). Range check mode passes with valid control of the model from 30 meters away. Release the button to allow full power transmission.
