Product Disclaimer
Product information may vary between manufacturers, suppliers, firmware versions, and production batches. Please verify the actual module specifications, supported bands, carrier compatibility, and interface details before use.
Product images are for illustrative purposes only and may differ from the actual product in colour, connector placement, component markings, or other visual details.
Important Note
SIM Card
A compatible Micro SIM card with an active cellular service is required for network connectivity.
Antenna
A suitable 4G antenna connected through the SMA connector is required for cellular operation.
Power Supply
The modem can require significant current during cellular transmission, with peak requirements potentially reaching approximately 2A according to the supplied information. Use a stable 5V power source capable of handling these current demands.
GPS / GNSS
This standard version does not support GNSS/GPS. A GNSS-enabled version should be used when satellite positioning is required.
