USI has over 20-year experience in wireless connectivity industrial and over 1 billion modules shipment as proven record. Our technology coverage is from 2.4GHz/5GHz to 60GHz and Sub-GHz recently could serve customers broad applications. Through miniaturization process, we can provide the smallest WiFi module to portable device and accelerate developing time to market.
Low-Power Wide-Area Network (LPWAN) or Low-Power Network (LPN) is a type of wireless telecommunication wide area network designed to allow long range communications at a low bit rate among things (connected objects), such as sensors operated on a battery. The low power, low bit rate and intended use distinguish this type of network from a wireless WAN that is designed to connect users or businesses, and carry more data, using more power.
USI works with SEMTECH and STMicroeletronics to announce this low cost, low power wide area network (LPWAN) wireless module that supports the LoRaWAN long range wireless protocol and AT-master command stack. This stand-alone compact module measures just 12 x 13 x 2 mm, a metal shielded package and comprises a SEMTECH SX1272 ultra long range wireless transceiver and STMicroeletronics STM32L0 series ARM Cortex M0+ 32 bit microcontroller (MCU).
This USI WM-SG-SM-42 module provides a variety of interface like LPUART, SPI, or I2C for peripheral. 3ch ADC and up to 20 GPIOs provide a plenty of flexibility for connecting sensors, switches and status LEDs, and the module is powered from a 2.0 to 3.6 VDC supply. The USI WM-SG-SM-42 module has been certified radio regulatory approvals for operating in the 868(CE) and 915(FCC) MHz industrial, scientific and medical (ISM) spectrum in most geographical regions of the world. The LoRaWAN certified makes it compatible with standard LoRa Network too.
