|
| 145 | +| **Reverse Recovery Time (trr)** | Slow (~2–30 µs) | Very fast (nanoseconds, <100 ns) | |
|
| 146 | +| **Power Dissipation** | Higher due to VF and switching losses | Lower, very efficient | |
|
| 147 | +| **Frequency Use** | Low frequency rectification (50/60 Hz AC) | High frequency SMPS, DC-DC converters | |
|
| 148 | +| **Package** | Through-hole (DO-41) | Surface-mount (SMA/SMB/SMC) | |
|
| 149 | +| **Temperature Range** | –65 to +150 °C | –55 to +150 °C | |
|
| 150 | +| **Typical Applications** | Power supply rectifier (mains, chargers) | Buck/boost converters, freewheeling diode in switching regulators | |
|
| 151 | + |
|
| 152 | + |
|
| 153 | +For **low-voltage DC** power paths (e.g., 5V, 12V, battery systems, USB, DC-DC converters): |
|
| 154 | +→ SS34 is much better (low drop, higher current, efficiency). |
|
| 155 | + |
|
| 156 | +For **high-voltage AC** rectification (like 220V/110V mains power supplies): |
|
| 157 | +→ 1N4007 is safer (handles up to 1000 V). |
|
| 158 | + |
|
| 159 | +⚡ In most modern “power-through” / **series protection** roles at DC (5–24 V), SS34 wins because the low voltage drop keeps the system efficient and avoids unnecessary heating. |

|
| 46 | +| ------------------------ | ------------------------------- | ------------------------------------------------------------------------------------------ | |
|
| 47 | +| Pin 1 (Red, VCC) | Power (3.7–13.2V) | `VBAT` pad (from 2S battery). Don’t use 5V pad. | |
|
| 48 | +| Pin 2 (Black, GND) | Ground | Any `GND` pad on X12 | |
|
| 49 | +| Pin 3 (Gray, RX) | O4 RX (expects data from FC TX) | Connect to `TX` pad of a free UART (e.g. TX1) | |
|
| 50 | +| Pin 4 (White, TX) | O4 TX (sends data to FC RX) | Connect to `RX` pad of same UART (e.g. RX1) | |
|
| 51 | +| Pin 5 (Black, GND) | Ground | Extra GND (optional, can join same pad as Pin 2) | |
|
| 52 | +| Pin 6 (Yellow, SBUS/HDL) | DJI remote signal | Connect to `SBUS` pad (if available) or `RX` of a free UART configured for serial receiver | |
|
| 53 | + |
|
| 54 | +--- |
|
| 55 | + |
|
| 56 | + |
|
| 57 | +## 4. Betaflight Setup |
|
| 58 | + |
|
| 59 | +1. **Ports Tab** |
|
| 60 | + - Enable MSP on the UART you wired O4 to (e.g. UART1). |
|
| 61 | + - If using DJI controller via SBUS, set the SBUS UART as “Serial RX.” |
|
| 62 | + |
|
| 63 | +2. **Configuration Tab** |
|
| 64 | + - Enable “OSD” and “Serial RX” (if using DJI controller). |
|
| 65 | + |
|
| 66 | +3. **Receiver Tab** |
|
| 67 | + - Set “Serial-based receiver” → SBUS (or DJI HDL depending on firmware). |
|
| 68 | + |
|
| 69 | +4. **Disable internal VTX** |
|
| 70 | + - Since O4 already provides HD video transmission, disable or ignore the X12’s built-in OpenVTX to avoid interference. |
|
| 71 | + |
|
| 72 | + |
|
| 73 | +## Using DJI O4 |
|
| 74 | + |
|
| 75 | +### Option 1: O4 for Video Only (Recommended) |
|
| 76 | +- **O4 Air Unit** |
|
| 77 | + - Connect `VCC (9–12V)` → X12 9V pad |
|
| 78 | + - Connect `GND` → X12 GND pad |
|
| 79 | +- **ELRS PWM Receiver** |
|
| 80 | + - Handles all control inputs (8 channels → FC or servos) |
|
| 81 | +- **Result:** |
|
| 82 | + - O4 = HD video transmission |
|
| 83 | + - ELRS = full radio control ✅ |
|
| 84 | + |
|
| 85 | +--- |
|
| 86 | + |
|
| 87 | +### Option 2: O4 for Video + Control |
|
| 88 | +- **O4 Air Unit** |
|
| 89 | + - `VCC` → 9V pad on FC |
|
| 90 | + - `GND` → GND pad on FC |
|
| 91 | + - `SBus Out` → RX pad (UART) on FC |
|
| 92 | +- **Result:** |
|
| 93 | + - O4 provides both video and RC link |
|
| 94 | + - No ELRS receiver needed |
|
| 95 | + |
|
| 96 | +--- |
|
| 97 | + |
|
| 98 | +### Option 3: Mixing O4 + ELRS PWM |
|
| 99 | +- **Possible but not recommended** |
|
| 100 | + - FC can only use **one main RX input** |
|
| 101 | + - PWM receivers bypass advanced FC features |
|
| 102 | + - Can cause conflicts between DJI link and ELRS link |
|
| 103 | + |
|
| 104 | +--- |
|
| 105 | + |
|
| 106 | +### ✅ Best Practice |
|
| 107 | +- **Use ELRS PWM Receiver** for **control** |
|
| 108 | +- **Use DJI O4 Air Unit** for **HD video** only |
|
| 109 | + |
|
| 110 | + |
|
| 111 | +## Using a Phone to View DJI O3 or O4 |
|
| 112 | + |
|
| 113 | +### DJI O3 Air Unit |
|
| 114 | + |
|
| 115 | +- **Direct phone connection:** ❌ Not supported |
|
| 116 | + - O3 outputs **digital HD FPV** via DJI protocol. |
|
| 117 | + - Requires **DJI FPV Goggles (V2, Goggles 2, or Integra)** to decode and view live video. |
|
| 118 | +- **Indirect phone viewing:** ✅ Possible |
|
| 119 | + - Connect phone/tablet to **DJI FPV Goggles via USB-C**. |
|
| 120 | + - Use **DJI Fly app / DJI Assistant 2** for: |
|
| 121 | + - Live video streaming (slightly higher latency) |
|
| 122 | + - Firmware updates |
|
| 123 | + - OSD / settings view |
|
| 124 | + - **Phone alone cannot replace goggles**. |
|
| 125 | + |
|
| 126 | +--- |
|
| 127 | + |
|
| 128 | +### DJI O4 Air Unit |
|
| 129 | + |
|
| 130 | +- **Direct phone connection:** ❌ Not supported |
|
| 131 | + - O4 also outputs **digital HD FPV** via its own DJI protocol. |
|
| 132 | + - Requires **DJI Goggles 3 / Goggles 2 / N3** to decode the signal. |
|
| 133 | +- **Indirect phone viewing:** ✅ Possible |
|
| 134 | + - Connect phone/tablet to **DJI Goggles 3 via USB-C**. |
|
| 135 | + - Use DJI Fly app for spectator mode, recording, or monitoring. |
|
| 136 | + - **Phone alone cannot replace goggles**. |

|
| 158 | +## Activation Details |
|
| 159 | + |
|
| 160 | +**Purpose of Activation** |
|
| 161 | + |
|
| 162 | +- Registers the Air Unit with DJI servers. |
|
| 163 | +- Enables firmware updates. |
|
| 164 | +- Links the Air Unit to your DJI account. |
|
| 165 | +- Ensures anti-counterfeit verification and proper functionality. |
|
| 166 | + |
|
| 167 | + |
|
| 168 | +## Technical Notes |
|
| 169 | + |
|
| 170 | +- **Video-only use does not bypass DJI GEO restrictions.** |
|
| 171 | +- The O4 cannot be used standalone on a phone to circumvent restrictions. |
|
| 172 | +- Only **authorized exemptions** granted by aviation authorities allow legal operation in restricted areas. |
|
| 173 | + |
|
| 174 | + |
|
| 175 | +Without activation: |
|
| 176 | + |
|
| 177 | +- The O4 may **not function properly** |
|
| 178 | +- Video transmission or OSD features may be **disabled** |
|
| 179 | +- You cannot perform **firmware updates** |

|
| 58 | + |
|
| 59 | +### 1. Walksnail Avatar / Avatar Kit |
|
| 60 | + |
|
| 61 | +- **Direct Phone/Tablet Viewing:** ✅ Yes |
|
| 62 | +- **How it works:** |
|
| 63 | + - Connects via **Wi-Fi** to Walksnail mobile app (iOS/Android) |
|
| 64 | + - Provides live HD video streaming with ~100–200 ms latency |
|
| 65 | +- **Limitations:** |
|
| 66 | + - Latency higher than DJI digital FPV systems (less suitable for high-speed racing) |
|
| 67 | + - Limited to 2.4 GHz/5 GHz Wi-Fi range (~50–100 m unobstructed) |
|
| 68 | +- **Use case:** |
|
| 69 | + - Casual FPV flying, spectators, or short-range FPV without goggles |
|
| 70 | + |
|
| 71 | +--- |
|
| 72 | + |
|
| 73 | +### 2. CaddxFPV Vista / Nebula Pro (HD Digital) |
|
| 74 | + |
|
| 75 | +- **Direct Phone/Tablet Viewing:** ❌ Usually No (requires goggles) |
|
| 76 | +- **Details:** |
|
| 77 | + - Vista module outputs HD FPV via **Caddx digital protocol** (similar to DJI) |
|
| 78 | + - Goggles (Caddx Goggles, Fat Shark HDO2 with module, or RapidFIRE) required for low-latency live feed |
|
| 79 | +- **Note:** |
|
| 80 | + - Some newer Nebula Pro versions include **Wi-Fi streaming** for phone apps, but latency is higher (~150–300 ms) |
|
| 81 | + - Not recommended for racing or freestyle without goggles |
|
| 82 | + |
