7. Тэхнічнае абслугоўванне
- Keep the core board in a dry environment and protect it from dust and moisture.
- Пазбягайце ўздзеяння на модуль экстрэмальных тэмператур або прамых сонечных прамянёў.
- Handle the board with care to prevent physical damage to components or pins.
- Забяспечце належнае электразабеспячэнне ў межах названага аб'ёмуtage range (5-16V DC) to prevent damage.
- Regularly check connections for secure fit, especially for antennas and power.
8. Выпраўленне непаладак
- Модуль не ўключаецца: If the module does not power on as expected, verify the power supply connections and ensure the voltage is within the 5-16V DC range. If using the POWRKEY solution, confirm that resistor R5 has been removed and the PWK/RST pin is shorted to 3.3V. Remember that the default boot is automatic, and issues with the POWRKEY method are not considered product defects.
- No Network Indication: Check the antenna connection to the IPEX 1 RF seat. Ensure the SIM card is correctly inserted into the MIRCO SIM holder. Verify that the network band configuration matches your region's requirements.
- Праблемы з перадачай дадзеных: Confirm that the 2.54 PIN connections are secure and that your external device is correctly configured for data communication. If using USB for RNDIS/PPP, ensure the XH2.0 terminals are properly welded and drivers are installed.
- GNSS Signal Loss: Ensure the GNSS antenna is properly connected and has a clear line of sight to the sky.
