+

+

+

+Note 1: DragonLink provides a 56Kbaud transparent link for telemetry, allowing full MAVLink telemetry to/from the vehicle from the transmitter module. Dragonlink is an add-on module to the transmitter, such as an FRSky Taranis or RadioMaster T16. See DragonLink RC Systems. MTP (Mavlink to Passthru) converters are available to allow direct display of MAVLink Telemetry data on OpenTX transmitters using Yaapu Telemetry LUA Script.

+

+Note 2: See Yaapu FrSky Telemetry Script for OpenTX. The ability to change parameters over FRSky telemetry from an Open TX compatible transmitter in addition to displaying the telemetry data is possible. Most FRSky compatible transmitters use OpenTX. Note that R9 systems are not quite Long Range, but much further range than normal FRSky systems, themselves at the very high end of the Short Range category at 1.6-2km range.

+

+Note 3: ArduPilot provides a means to send its telemetry data via CRSF such that it can be displayed on OpenTX transmitters using the Yaapu Telemetry LUA Script. The ability to change parameters over CRSF telemetry from an Open TX compatible transmitter in addition to displaying the telemetry data is also possible. See TBS Crossfire Telemetry

+

+Note 4: ELRS (ExpressLRS) is a flexible open-source system that can output CRSF, SBUS, or MAVLink (with embedded RC) protocols. Telemetry requires the use of CRSF or Mavlink, and the receiver must be wired to a full UART. See ExpressLRS site <https://www.expresslrs.org/> and TBS CRSF/ ELRS for more information.

+

+Note 5: The mLRS project is firmware designed specifically to carry both RC and MAVLink. The usable telemetry speed varies by the chosen mode and is managed via RADIO_STATUS flow control. It uses the CRSF (TBS Crossfire) RC protocol on both the receiver and Tx module. It also integrates full MAVLink telemetry via serial connections on the Tx module and the receiver.

+

+Note 6: Vendor Specific Telem means that they accomodate sensor additions to the vehicle and can display the information on certain Vendor specific TXs but do not send ArduPilot telemetry from the vehicle to ArduPilot compatible GCS or OpenTX display scripts.

+

+Note 7: The receiver must support i-BUS telemetry (look for a SENS port on the receiver or check the product specifications).

+

+Note 8: These systems have integrated HD video transmission from Ethernet or HDMI camera systems in addition to RC control and vehicle telemetry.

+# CRSF-dat

+

+CRSF (Crossfire Serial Protocol) is a low-latency, high-speed serial protocol developed by **Team BlackSheep (TBS)** for communication between radio receivers (like TBS Crossfire Nano RX) and flight controllers.

+

+It’s used in RC applications (especially FPV drones) to transmit RC channel data, telemetry, and link status over a compact serial format.

+

+CRSF packets are binary data. Here's the basic structure of a CRSF packet:

+

+## CRSF Packet Structure (General)

+

+| Byte Index | Name | Description |

+|------------|----------------|---------------------------------------------|

+| 0 | Device Address | Who is sending (e.g., RX, TX) |

+| 1 | Frame Length | Length of payload + 1 (type byte + data) |

+| 2 | Frame Type | Type of data (e.g., RC channels, telemetry) |

+| 3 - N | Payload | Actual data, varies by Frame Type |

+| Last Byte | CRC | Checksum for packet validation |

+

+

+This is how a typical RC channel data packet might look (in hex):

+

+C8 18 16 A1 84 3F C1 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 9E

+

+## RC Channel Encoding (Packed 11-bit)

+

+Each RC channel is packed as 11-bit little-endian integers, with up to 16 channels per frame. Example values:

+

+- 1000 → channel center

+- 172 → min

+- 1811 → max

+

+## read data via serial

+

+Yes, you can use a serial port to read CRSF data, because CRSF is a serial protocol — specifically, a half-duplex, asynchronous UART protocol using 8N1 (8 data bits, no parity, 1 stop bit).

+

+### 📡 CRSF over Serial – Quick Guide

+

+- **Baud rate**: 420000 or 115200 (depends on TX/RX version or setting)

+- **Protocol**: UART (8N1)

+- **Signal direction**: Half-duplex (same wire for TX and RX)

+- **Voltage**: 3.3V (NOT 5V safe on most Crossfire receivers)

+- **Typical usage**: Read CRSF data from TBS Nano RX or TX

+

+#### 🧰 What You Need:

+- A microcontroller or board with UART support (e.g., Arduino, ESP32, STM32, Raspberry Pi)

+- Logic-level conversion (if needed for 3.3V safety)

+- CRSF-compatible device (e.g., TBS Crossfire Nano RX)

+

+Code Concept (Pseudocode)

+

+

+ Serial.begin(420000); // Or 115200 for some TX modules

+

+ void loop() {

+ if (Serial.available()) {

+ uint8_t byte = Serial.read();

+ // Process CRSF packet bytes here

+ }

+ }

+

+

+

+## via ardupilot

+

+If you wish to use telemetry then a receiver can be connected to a UART utilizing the CRSF protocol.

+

+CRSF is a full-duplex protocol that supports integrated telemetry and a number of other features. Connect the RX pin of the UART to the CRSF TX pin of the CRSF device and vice versa. Currently a full-duplex UART connection is required. For best performance a UART with DMA capability on its RX port is desirable, but not required. A message will be displayed once on the GCS console, if connected to a UART without this capability on an F4/F7 based autopilot.

+

+## Frequently Asked Questions (FAQ)

+

+**Q1: Can this receiver bind with a transmitter module (TX module) from brand XXX?**

+**A:** The ELRS project is open-source. Therefore, as long as the TX module uses the ELRS protocol, regardless of the brand, they can bind with each other, provided three conditions are met:

+ 1. **Same Frequency:** Both must operate on the same frequency band (e.g., both 2.4GHz or both 915MHz).

+ 2. **Matching Firmware Version:** The firmware versions must be identical. For example, if the TX module is flashed with firmware version 2.5.0, the receiver must also be flashed with version 2.5.0.

+ 3. **Binding Phrase:** Either both devices have no binding phrase set, or they both have the exact same binding phrase configured.

+

+**Q2: How do I enter binding mode?**

+**A:** After soldering the receiver, quickly power cycle the aircraft three times: power on then immediately power off, power on then immediately power off, power on and leave it on. Each power cycle interval should be less than 1.5 seconds. If performed correctly, the receiver's LED will flash quickly twice in a repeating pattern, indicating it is in binding mode. Then, use the bind function/button on your remote controller (often found in the ELRS Lua script). Once binding is successful, the receiver's LED will turn solid.

+

+**Q3: The first time I used my receiver, it wouldn't enter binding mode, and the LED stayed solid. Why?**

+**A:** We've encountered this issue in support cases. It's often caused by an abnormality on the flight controller's TX/RX UART port, which forces the receiver into bootloader/firmware flashing mode upon power-up. Switching the receiver connection to a different, functional TX/RX UART port on the flight controller usually resolves this.

+

+**Q4: Why is my receiver's LED flashing quickly and continuously?**

+**A:** If the receiver is powered on but doesn't enter binding mode (or if it's already bound but the remote controller is off), it will automatically enter Wi-Fi firmware update mode after approximately 60 seconds of not receiving a signal. The fast flashing indicates Wi-Fi mode is active.

+

+**Q5: How do I enter Wi-Fi mode to update the receiver's firmware?**

+**A:** As mentioned above, simply power on the receiver and wait. If it doesn't connect to a transmitter within about 60 seconds, it will automatically enter Wi-Fi update mode, indicated by the rapidly flashing LED.

+

+## 📡 What is SBUS? — Simple Explanation

+

+**SBUS (Serial Bus)** is a digital protocol used in RC systems to send multiple control signals (channels) over a single wire.

+

+---

+

+### 🧩 Key Features

+

+- 🔢 **Up to 16 channels** in one signal

+- 💬 **Digital serial protocol**

+- 📦 Sends data in **serial frames**

+- ⏱️ **100,000 baud**, **inverted UART**

+- ↪️ Invented by **Futaba**, widely used (FrSky, Radiolink, etc.)

+- 🧠 Needs **inversion** to be read by normal UART (hardware or software)

+

+---

+

+### 🧱 Simple Analogy

+

+> SBUS is like 16 people taking turns speaking very fast on one microphone.

+> Each frame contains all channel values packed tightly together.

+

+---

+

+### 🧪 Data Frame Structure

+

+Each SBUS frame is 25 bytes:

+

+| 1 byte | 22 bytes | 1 byte | 1 byte |

+| ------ | ----------- | ------ | ------ |

+| Header | 16 channels | Flags | End |

+

+

+

+- **Header**: 0x0F

+- **End**: 0x00

+- Sent **every ~9ms** (111Hz refresh rate)

+

+---

+

+### 🔌 Common Use Cases

+

+- RC Receiver → Flight Controller (e.g., FrSky RX to Betaflight FC)

+- RC Receiver → Microcontroller (Arduino, ESP32)

+- RC → Servo controller boards (if SBUS supported)

+

+---

+

+### ⚖️ SBUS vs PWM vs PPM

+

+| Feature | SBUS | PWM | PPM |

+|---------------|-------------|---------------|---------------|

+| Channels | 16 | 1 per wire | 8 (typically) |

+| Wires needed | 1 | 1 per channel | 1 |

+| Type | Digital | Analog pulse | Analog pulse |

+| Speed | Very fast | Slow | Medium |

+| Latency | Very low | High | Medium |

+

+---

+

+### 🧰 Tip for Developers

+

+To read SBUS using a microcontroller:

+- Use **UART** at **100000 baud**, **8E2**, **inverted signal**

+- Some MCUs (like ESP32) support inversion natively

+- Otherwise, use an **inverter circuit** or a software decoder

+## parts of the FPV drones

+

+- **Flight Controller**: The brain of the drone, responsible for stabilizing and controlling the flight. It processes data from sensors and executes commands from the pilot or autopilot system.

+

+- **Electronic Speed Controller (ESC)**: Controls the speed of the motors by adjusting the power supplied to them. ESCs are essential for smooth and responsive flight.

+

+- **Motors**: Provide the thrust needed for flight. Brushless motors are commonly used in FPV drones due to their efficiency and power.

+

+- **Propellers**: Generate lift by spinning rapidly. The size and pitch of the propellers can significantly affect the drone's performance and flight characteristics.

+

+ - [[SCU1059-dat]]

+

+- **Camera**: Captures real-time video for FPV flying. FPV cameras are designed to provide low-latency video transmission to the pilot's goggles or screen.

+

+- [[VTX-dat]]: Video Transmitters are commonly referred to as VTX units. They are responsible for transmitting the video signal from the camera to the pilot's goggles or screen. VTX units come in various power levels and frequencies, allowing pilots to choose the best option for their flying environment.

+- **Antenna**: Enhances the signal strength and range of the VTX. Different antenna types (e.g., dipole, patch, circular polarized) can be used to optimize performance.

+

+- **ExpressLRS**: A long-range radio control link for FPV drones, known for its low latency and high refresh rates. It is an open-source project that competes with other systems like Crossfire and ELRS.

+

+ - [[ELRS-dat]]

+

+- **Goggles**: Wearable displays that allow pilots to see the live video feed from the drone's camera. They often include features like head tracking and DVR (Digital Video Recorder) capabilities.

+

+## standards

+

+### PNP stands for "Plug and Play."

+

+In the context of FPV drones, a PNP version means that the drone comes mostly assembled but does not include a radio receiver.

+

+Here's why it doesn't include a receiver:

+

+Flexibility: PNP versions cater to experienced FPV pilots who already have their preferred radio transmitter and receiver. This allows them to use their existing equipment and avoid paying for redundant components.

+Customization: Pilots might have specific receiver requirements based on their radio system (e.g., TBS Crossfire, ELRS, FrSky). Offering a PNP version lets them choose the exact receiver that's compatible with their setup.

+Cost Savings: By excluding the receiver, the manufacturer can offer the PNP version at a lower price point, making it attractive to those who don't need the included receiver.

+In short, PNP versions are designed for users who want to use their own radio gear and prefer to avoid unnecessary costs or compatibility issues.
