❶ 【STM32 UPGRADE | 128K ROM STORAGE】⬆️ 💾 🚀Upgraded ARM Cortex-M3 STM32F103CBT6 core replaces legacy ATmega328P, delivering 128K ROM + 20K RAM — double the protocol storage capacity for future firmware expansion and faster processing response.

❷ 【4-IN-1 RF CHIPS | 70+ PROTOCOLS ALL-IN-ONE】📡 🔗 🌍Integrates CC2500 + NRF24L01 + A7105 + CYRF6936 four RF transceivers on single PCB. Covers Walkera DEVO, Spektrum DSM2/DSMX, Flysky, FrSky D16/V8, Futaba SFHSS, Hubsan, WLtoys, Eachine E010, Assan and beyond — fly ALL your fleets with ONE module.

❸ 【DUAL MODE FLEXIBILITY | SERIAL + PPM】🎮 ⚡ 🔄Serial Mode (0-position): Full protocol access via OpenTX/EdgeTX/erSky9X radio menu — switch & bind directly on transmitter screen. PPM Mode (1-F positions): 70 protocols across 5 preset groups, rotary-dial selection for legacy radios without smart menu support.。

❹ 【WIDE RADIO COMPATIBILITY | PLUG & FLY】✅ 📻 ✈️Native fit for FrSky X9D / X9D Plus, Jumper T16 / T18 / T-Pro, RadioMaster TX16S / TX18S / Zorro, and all JR-module-bay transmitters. Auto-detects PPM signal or MULTI serial telemetry — no soldering, no adapter, power on and bind.

❺ 【+22dBm OUTPUT | 5-14V WIDE VOLTAGE】💪 📶 🔋22dBm RF power ensures solid long-range link stability. Operates from 5V to 14V input — compatible with transmitter battery rails from 2S LiPo to 3S LiFe, regulated onboard. Low <100mA draw preserves flight-ready radio endurance.

The main difference from the original ATemga328P version is the space upgrade, which can store more protocols.

The hardware circuits of the three-in-one and four-in-one tuner are all originally designed by our store. At present, there are counterfeit and plagiarized products in the market. Due to the inaccurate shell size and poor compatibility, there is not a small difference from the store's products, please pay attention to purchase.

Overview:

This four-in-one tuner module integrates four RF chips, CC2500, NRF24L01, A7105, and CYRF6936, on a single circuit board. It can identify the PPM signal output by the remote control, and then convert it into the corresponding remote control protocol to realize the control of the receiver or the aircraft. The currently supported protocols include: Walkera DEVO, Horizon DSM2, Fusi, Yisky, Ruisky, Weili, Harbson, Chiyuan, Futaba SFHSS Assan and other agreements.

This tuner can control multiple four-axis, helicopters and fixed wings of different brands more flexibly and conveniently. Due to the continued use of the remote control you are familiar with, the operation feel and flying experience are better.

Working parameters:

Working voltage: 5-14 volts Working current: <=100mA

Working frequency: 2.4G ISM band RF power: +22dBm

Main control chip: STM32F103CBT6 (128K ROM, 20K RAM)

Size: 55x41x7mm, without buttons Net weight: 23g, with antenna

The tuner has two working modes: PPM mode and serial port mode.

In PPM mode, there are 31 different protocols corresponding to the 16 positions of the rotary coding switch (protocol 0 is reserved for serial port mode). Please refer to the list on the previous page of the manual for the correspondence between the two.

When the green light is off, you can use the knob to select protocols No. 1 to 15, and when the green light is on, you can select protocols No. 16 to 31.

If you need to turn on or turn off the green light, please follow the steps below:

Turn off the remote control, point the rotary coding switch to "0", press and hold the black link button on the tuner, then turn on the remote control, release the button after 3 seconds, and then you can see the green light switch between on and off , The optional protocol will be switched at the same time.

In PPM mode, normal use operation:

1. Fix the tuner, install the antenna, and turn on the PPM signal output on the remote control

2. According to the following default protocol list and your receiver type, point the tuner knob (the end of the handle with the vertical groove) to the corresponding gear.

3. When the linking has been completed, turn on the power switch of the remote control, the red indicator light on the tuner will always be on, and then the tuner will start to work normally, and then turn on your receiver (or airplane).

4. The tuner cannot switch the protocol during normal use. If you need to switch the protocol, please turn off the power first, adjust the knob, select the desired protocol, and then power on again.

5. If there is no valid PPM signal input, the red light will flash slowly.

In PPM mode, linking operation:

1. Turn on your receiver (or airplane) and follow the instructions of the receiver to enter the linking mode.

2. Press and hold the black link button on the tuner, turn on the remote control and wait to enter the system interface. After 3 seconds, release the link button, you can see the red indicator flashes quickly, indicating that the tuner enters the link mode. When the linking is over, the red light is always on.
