This Quectel EC25 Mini PCIe is a series of LTE category 4 module adopting standard PCI Express® MiniCard form factor (Mini PCIe). It is optimized specially for M2M and IoT applications and delivers 150Mbps downlink and 50Mbps uplink data rates.
The module is backward-compatible with existing EDGE and GSM/GPRS networks, ensuring that it can be connected even in remote areas devoid of 4G or 3G coverage.
EC25 supports Qualcomm® IZat™ location technology Gen8C Lite (GPS, GLONASS, BeiDou, Galileo and QZSS). The integrated GNSS greatly simplifies product design and provides quicker, more accurate and more dependable positioning.
EC25 supports multiple-input multiple-output (MIMO) technology, a cutting-edge antenna technology capable of transmitting multiple data streams on multiple transmitters to multiple receivers. The antennas at each end of the communication circuit are combined to minimize errors and optimize data speed. The module also combines high-speed wireless connectivity with embedded multi-constellation high-sensitivity GNSS receiver.
A rich set of Internet protocols, industry-standard interfaces and abundant functionalities (USB drivers for Windows XP, Windows Vista, Windows 7/8/8.1/10, Linux(Raspian), Android/eCall) extend the applicability of
the module to a wide range of M2M applications such as an industrial router, industrial PDA, rugged tablet PC, minicomputers like Raspberry Pi, video surveillance and digital signage.
You can easily insert a Mini PCIe module in Sixfab Base Shield then start using cellular internet with your Raspberry Pi. Both UART and USB communication with modules is available.
- With the Sixfab Base Shield, you can easily use EC25 with your projects.

!WARNING: When you use the EC25 with Sixfab Base Shield, may all features not be enabled in the shield.
EC25 antenna interfaces include a main antenna interface, an Rx-diversity antenna interface which is
used to resist the fall of signals caused by high-speed movement and multipath effect and a GNSS
antenna interface. The impedance of the antenna port is 50Ω.
For the just cellular connection, you’ll need just connect an antenna to the main antenna port. To obtain better Rx-sensitivity and signal reception, we’d recommend an additional antenna to Rx-diversity antenna port. Rx-diversity function(ANT_DIV) is enabled by default.
All of the antenna connectors are ECT818000117. This is compatible with the Hirose U.FL(known by a variety of
names including AMC, UMCC, IPX) connectors. The recommended RF connector is UF.L-R-SMT.
