1 Description
SPSGPE is a hardware LGA-SMT module for easy development of high performance wireless
network applications for a wide range of applications.
Compact-sized, low power and fully integrated, SPSGPE is available in 3 versions:
SPSGPE-433 operating on ETSI 433 MHz band
SPSGPE-868 operating on ETSI 868 MHz band
SPSGPE-915 operating FCC 915 MHz band.
All versions have the same pin-out and mechanical shape.
SPSGPE is based on SPIRIT1 RF sub-GHz transceiver (with integrated SMPS) and
STM32L151RDY6 microcontroller by ST Microelectronics. Balun and filtering network are
embedded in the module. An external antenna can be connected through one pin of the module
which requires an impedance-controlled track of 50 Ω. The UART host interface and USB device
interface allow simple connection to an external microcontroller with a standard firmware or a
host computer, enabling AT commands to facilitate RF configuration, data transmission and
reception, using simple point-to-point communication. Selected STM32L1 GPIO and peripherals
are available to interface external devices and enable user applications. Advanced features of
SPIRIT1 radio are also accessible.
SPSGPE is designed and engineered to build OEM solutions and applications primarily in the
following domains:
Internet of Things (IoT) and Machine-to-Machine (M2M);
Smart Cities;
Smart Grids and Energy Management;
Home & Building Automation;
Wireless Sensor Networks;
Data acquisition equipment management;
Industrial condition and asset monitoring.
