5. Тохиргоо
5.1 Модуль суурилуулах
- Identify the Nano standard 8-pin connector slot on your compatible radio transmitter (e.g., Zorro, Pocket, MT12 Radio).
- Carefully align the Bandit RF Module with the connector slot.
- Gently push the module into place until it is securely seated. Ensure the connection is firm to prevent intermittent signal loss.
- Attach the 915/868MHz T Antenna to the module's antenna connector. Hand-tighten only; do not overtighten.
5.2 Эрчим хүчний холболт
The module requires an external power source via the XT30 connector.
- Connect the provided XT30 power cable to the XT30 port on the module.
- Connect the other end of the XT30 cable to a DC power source providing 6V to 16.8V. Ensure correct polarity.
5.3 Binding Process (ExpressLRS)
Refer to the official ExpressLRS documentation for detailed binding procedures. Generally, the process involves:
- Power on your radio transmitter with the Bandit module installed.
- Navigate to the ExpressLRS Lua script or menu on your radio.
- Select the 'Bind' option.
- Power on your ExpressLRS receiver (not included) within the binding window. The module and receiver should establish a connection.
- Confirm successful binding via the OLED screen on the module or the radio's display.
6. Ажиллаж байгаа
6.1 Үндсэн үйл ажиллагаа
Once powered on, the OLED screen will display operational information such as current power output, refresh rate, and connection status. Use the 5-directional navigation key to:
- Цэсүүдийг удирдах: Move up, down, left, or right through menu options.
- Сонгох/Баталгаажуулах: Press the center button to select an option or confirm a setting.
- Гарах/Буцах: Often, a long press or a specific direction will exit a menu or go back.
6.2 Power Output and Refresh Rate
The module supports up to 1 Watt (30dBm) power output and packet rates up to 200Hz. These settings can typically be adjusted via the ExpressLRS Lua script on your radio or directly through the module's menu, if available. Higher power output increases range but also power consumption and heat generation.
6.3 Холболт
The Bandit module includes Wifi and Bluetooth support, which can be used for firmware updates, configuration, and other advanced features as supported by the ExpressLRS ecosystem.
7. Засвар үйлчилгээ
- Цэвэрлэгээ: Use a soft, dry cloth to clean the module. Avoid using liquids or solvents.
- Хадгалах: Модулийг нарны шууд тусгал болон хэт өндөр температураас хол, хуурай, сэрүүн газар хадгална уу.
- Програм хангамжийн шинэчлэлтүүд: Regularly check for and install the latest ExpressLRS firmware updates to ensure optimal performance and access to new features. Updates can typically be performed via Wifi.
- Антенны арчилгаа: Ensure the antenna is not bent or damaged. A damaged antenna can significantly reduce range and performance.
8. Алдаа засах
- Модуль асахгүй байна: Check the XT30 power connection and ensure the power source is within the 6V-16.8V range and correctly polarized.
- Дохио байхгүй/муу хүрээ: Verify the antenna is securely attached and undamaged. Check power output settings. Ensure the receiver is powered and bound correctly.
- Холбогдох асуудлууд: Ensure both module and receiver are running compatible ExpressLRS firmware versions. Follow the binding procedure carefully.
- OLED дэлгэц харагдахгүй байна: Check power supply. If power is present, try restarting the module. If the issue persists, contact support.
- Хэт халалт: Ensure the module has adequate airflow. Reduce power output if operating in high ambient temperatures.
