Description
Hardware configuration
USB dongle assembly carrying an EC25 module. Use this page to select an adapter or assembled modem for evaluation and host integration. Confirm the board and modem configuration with your quotation.
Photographs and supplied items
The main image contains an EC25-AF module; another gallery image is labeled EC25-EUX. The reverse view shows a SIM holder and a small cable connector. The historical packaging photograph contains multiple assemblies. The AF-specific URL does not make the EUX photograph an AF product.
| Sales form | USB dongle assembly carrying an EC25 module. Distinguish an unpopulated adapter from an assembly supplied with a modem. |
|---|---|
| Module / board identity | Order by complete module P/N and adapter revision, not by the generic 4G/5G title. Historical photos identify examples and do not establish current availability. |
| Kit contents | Specify board-only or board-plus-module, antennas, RF cables, SIM requirements, USB cable, enclosure and power accessories. Only the quotation establishes the included items. |
| Power and host | Obtain the board input rating, connector polarity, output rail, peak-current capability and host requirements before connection. |
| Network and performance | Determined by the installed module, firmware, antenna, SIM and network. An adapter does not add radio bands or certify operator acceptance. |
Integration checks
Choose EC25-AF or EC25-EUX for the intended country/operator, then match the complete module P/N, firmware and dongle board revision. The small cable connector is not proof of a particular UART voltage or pinout. The original requirement for customer communication software remains; internet access is not promised as automatic plug-and-play.
Check mechanical clearance, cooling, antenna connectors, host driver version and application software before deployment. Do not insert or remove a module or SIM under power unless the matched instructions explicitly permit the operation.
Technical references
Quectel EC25 family resources cover the cellular module. The existing Muziot EC25 module and card selection pages keep their own document references. Neither a bare-module specification nor a certificate under the EC25 folder establishes the finished dongle ratings or certification.
Quectel EC25 official family reference – select the exact regional module before using the band table.
Request the applicable board specification, hardware instructions and compliance documents during enquiry follow-up. Adjacent-board manuals, module marks and historical family certificates do not establish the certification or tested performance of the quoted assembly. Current status and applicable hardware/software revisions require confirmation.
