Quectel EC25 LTE Modem
Quectel EC25 is a series of LTE category 4 module optimized specially for M2M and IoT
applications. Adopting the 3GPP Rel. 11 LTE technology, it delivers 150Mbit/s downlink and
50Mbit/s uplink data rates. Designed in the compact and unified form factor, EC25 is
compatible with Quectel MTS/HSPA+ UC20 module and multi-mode LTE EC20/EC21 module,
which allows for flexible migration among them in design and manufacturing.
EC25 contains 6 variants: EC25-V, EC25-J, EC25-A, EC25-AU, EC25-AUT and EC25-E. This
makes it 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.
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, Android/eCall)
extend the applicability of the module to a wide range of M2M and IoT applications such as
industrial router, industrial PDA, rugged tablet PC, video surveillance, and digital signage.
The Quectel EC25 CAT-4 LTE Modem module is powered by 3.8V.
It is connected to 96Boards carrier board USB0 (HS connector), UART0, I2C0, GPIO A,B,C,K
(LS Connector) and (u)SIM connector.
RF lines connected to two RF antenna jacks: Main and GNSS.
Four LEDs are used to indicate modem status.
