Description
Overview
The Quectel EC25 family comprises LTE Cat 4 modules using 3GPP Release 11. The bare modules use an LCC package. Mini PCIe modules and carrier-board assemblies are separate hardware forms and require their own interface and power-supply checks.
Photo and supplied configuration
The main photograph on this page shows an EC25-A module mounted on a carrier board; it is a board example, not a photo of every EC25 regional variant. Confirm whether your quotation is for a bare module, Mini PCIe module or board assembly, and confirm the complete part number, optional GNSS and included accessories.
Bare-module specifications
Reference: Quectel EC25 Series released specification V3.1, pages 1, 2 and 5. These electrical and mechanical values apply to the bare module, not automatically to the input connector of a carrier board.
| Technology | LTE Cat 4, 3GPP Release 11 |
|---|---|
| Package / dimensions | LCC; 29.0 x 32.0 x 2.4 mm |
| LTE-FDD peak rate | 150 Mbps DL / 50 Mbps UL; theoretical maximum |
| LTE-TDD peak rate | 130 Mbps DL / 30 Mbps UL for variants supporting TDD |
| Supply voltage | 3.3-4.3 V; typical 3.8 V |
| Temperature | Operating: -35 to +75 C; extended: -40 to +85 C |
| Interfaces | USB 2.0, UART, (U)SIM and other interfaces as specified for the selected variant |
| GNSS | Optional GPS/GLONASS/BDS/Galileo/QZSS; confirm the ordered configuration |
Selected regional variants
This is a selection aid, not the complete EC25 range. Use the full suffix when comparing bands; a shared EC25 family name does not make two variants interchangeable.
| EC25-A (photo label) | North America. LTE-FDD B2/B4/B12; no LTE-TDD; WCDMA B2/B4/B5; no GSM/EDGE listed. |
|---|---|
| EC25-E | LTE-FDD B1/B3/B5/B7/B8/B20; LTE-TDD B38/B40/B41; WCDMA B1/B5/B8; GSM/EDGE B3/B8. |
| EC25-EU | LTE-FDD B1/B3/B7/B8/B20/B28A; LTE-TDD B38/B40/B41; WCDMA B1/B8; GSM/EDGE B3/B8. |
| EC25-EUX | LTE-FDD B1/B3/B7/B8/B20/B28A; LTE-TDD B38/B40/B41; WCDMA B1/B8; GSM/EDGE B3/B8. Do not assume its other interfaces match EU. |
| Other variants and hardware forms | For AU/AUX/J/AF/V and other variants, use their individual columns. Use a separate Mini PCIe or carrier-board document for that hardware form. |
Specifications and supporting documents
Official EC25 Series specification V3.1 | Official LCC module document listing | Official Mini PCIe product information
The original V2.9 PDF remains available through the Datasheet Center. V3.1 updates the variant listing and software information; do not infer a supplied firmware version from a generic driver list. The current hardware listing includes EC25 Series Hardware Design V2.8; confirm document access and applicability before design work.
Regulatory and operator approvals vary by model and configuration. Request the applicable documents for the full part number and destination market during quotation. The EC25-A photo and the family specification are not certification evidence for every EC25 module or board.
Selection and quotation
Send the country, operator, full model suffix, host interface, required hardware form, optional features and quantity. Include your existing board information if you are planning a replacement.
