The Lemon Rx DSMP Plug and Go transmitter module is designed specifically for any JR module bay capable transmitter that supports PPM or 9XR-DSM protocol. Example of these transmitters are RadioMaster TX16s, TX12, FrSky Taranis Q X7 and Turnigy 9x just to name a few. The revolutionary DSMP protocol based on software defined radio packet allows full compatibility to all Horizon Hobby's DSMX or DSM2 compatible receiver as well as the bind and ready to fly model aircraft without any channel rescaling configuration required except the first 4 channels' order (TAER or namely Throttle, Aileron, Elevator, Rudder) need to be mapped. The module is designed to work with Lemon Rx or Spektrum-compataible aircraft receiver (not compatible with Spektrum surface receiver). 

Telemetry
Telemetry display and alert is supported with ErSky firmware under PPM / 9XR-DSM protocol. ErSky firmware can be dwonloaded at http://www.er9x.com/. For EdgeTX user, the LemonTx module DSMP protocol has been in limited testing in EdgeTX release 2.7 and appears to work correctly. However you are advised to do a proper range check and full channel functionality check before using it for serious model aviation.

The Lemon Rx DIY module is an electronic kit that addresses the need for RC modeler in legacy transmitter conversion. The module is designed to work with Lemon Rx or Spektrum-compataible aircraft receiver (not compatible with Spektrum surface receiver). 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 labeled "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.

Telemetry support with ErSky / EdgeTX firmware for non-vintage radio (See LMT0001 as a better alternative)
Although unlikely to be used, LMT0002 comes with telemetry serial UART output when a telemetry capable receiver is used. Telemetry display and alert is supported with ErSky firmware under PPM / 9XR-DSM protocol. ErSky firmware can be dwonloaded at http://www.er9x.com/. For EdgeTX user, the LemonTx module DSMP protocol has been in limited testing in EdgeTX release 2.7 and appears to work correctly. However you are advised to do a proper range check and full channel functionality check before using it for serious model aviation.

After almost 2 years of on going development since 2016, we have put variometer, energy meter (mAh, V, Curent) and just about every major telemetry parameter in one tiny package. LM0052 is the world smallest, true full-range telemetry system with build-in sensors along with diveristy receiver shrinked in the smallest possible package.

 
Highlight
- Very high accuracy barometer built-in to the receiver to provide altitude and vario information
- True Full-range diversity telemetry provides plane information in real-time as far as you can fly your plane with any DSMX or DSM2 compatible transmitter
- Energy metering system (mAh, V, Current) are included with the provided V/I sensing unit
- 2-stage failsafe best suited for gasoline / electric application (Selectable failsafe for pre-defined position as throttle only or all channel failafe in the event of signal absence)
- Diveristy extended antenna receiver with state-of-the-art RF circuit providing umatched performance of reception
- Real time RSSI output as analog voltage / displayed on transmitter A parameter
- Glider may use the inlcuded wiring for battery voltage sensing only if energy  metering system is not required for absolute weight reduction
- Optional diversity satellite maybe used to provide total of 4 receiving antennas
 
LM0052 telemetry range comparsion with Spektrum and Orange
The outstanding telemetry range of LM0052 are tested with Spektrum and Orange telemetry capable receiver as a basic performance benchmark. Please note that for fairness of this testing as the other receiver may not contain diveristy antenna unlike the LM0052, the setup is performed such that diveristy will have no advantage of any range improvement during this test.

- For (*1) V/I sensor may be required to purchase seperately on LM0051U, LM0052U and LM0041 if mAh consumed / current measurment is required

Quick start-up guide / tips

V/I sensor calibration
- V/I sensor would normally not need calibration with the LM0052 bundled unit
- V/I sensor can be calibrated following section F of LM0041 user manual
 
Step for setting failsafe
Fail-safe activates when the receiver no longer receivers signal (Eg. Transmitter is off / signal loss). There are 3 possible setting which are:
    - No signal output to servo
    - Output predefined throttle signal only
    - Output predefined signal for all channels
1) Insert bind plug
2) Provide power to the unit and bind the unit but do not remove bind plug
3) Set your transmitter to the perferred position as failsafe default output and hold it to this position.
3) press the button briefly will cause the green light to be in the following status. Press the button while maintain your perferred position of the channel:
     - Green LED status - none: No pulse to servo with the absence of correct reception
     - Green LED status - flashing: Throttle-only preset. Throttle position had been acquired as failsafe default output
     - Green LED status - solid: All-channel preset. All channels' position had been acquired as failsafe default ouptut
4) Remove bind plug
5) Turn off the transmitter now while power is still provided to receiver. You can now observe the failsafe status when no transmitter signal is present to the receiver. Please becareful that your propeller may turns if you set throttle channel above 0% in the event of signal losses. Failsafe can be useful as a last rsource to save plane for unexpected situation when the receiver is no longer receiving signal from transmitter such as interference problem.
