Quectel BG95-M3 Mini PCIe - LPWA Wireless Communication Module
The Quectel BG95-M3 Mini PCIe is a multi-mode, low-power wide-area (LPWA) wireless communication module designed in the standard Mini PCI Express (Mini PCIe) form factor.
It integrates Quectel's BG95-M3 cellular chip into a standard 52-pin Mini PCIe card layout. This allows developers to easily plug the cellular connectivity into industrial computers, embedded motherboards, or single-board computers.
 
Core Specifications & Key Features
Multi-Mode Connectivity: It supports LTE Cat M1 (eMTC), LTE Cat NB2 (NB-IoT), and fallback to EGPRS (2G) networks.
Data Rates: Under LTE Cat M1, it delivers maximum cellular speeds of 588 Kbps downlink and 1119 Kbps uplink.
Integrated GNSS: It features a built-in multi-constellation satellite receiver supporting GPS, GLONASS, BeiDou, Galileo, and QZSS.
Form Factor: Uses the standard Mini PCIe dimensions, measuring roughly 51.0mm × 30.0mm × 4.9mm.
Hardware Interface: Utilizes a USB 2.0 interface over the Mini PCIe pins for data transmission and AT commands. It typically includes on-board U.FL antenna connectors for both cellular and GNSS signals.
Industrial Grade: Operates reliably in harsh environments with an extended temperature range of -40°C to +80°C.
 
Typical Applications
Thanks to its ultra-low power consumption and global band support, this module is widely used in:
Smart metering (electricity, gas, and water meters)
Asset tracking and logistics fleet management
Smart city infrastructure and industrial automation
Wireless POS terminals
