Universal Scientific Industrial

(2016-12-19) USI today announced that it's going to launch a 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 STMicro STM32L0 series ARM Cortex M0+ 32 bit microcontroller (MCU). X' tal source integrated in the module offer accurate clock for the RF transceiver and lower system BOM.

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. 

The output power is adjustable between + 14 dBm for Europe market and +20 dBm for the US market, it fits customer needs such as long range applications or those where the end-device is sited in a poor signal location indoors.

The MCU includes 64 KB flash and 8KB RAM, and has embedded with user friendly AT-master command set for customer to integrate this module into their design and lower the SW development effort for Time to Market. The AT-master command set supports LoRaWAN protocol also.

"Having a module maker using our 32-bit  microcontroller solution  (STM32) to promote the LoRa technology such as USI, with its strong knowledge and product quality, reinforces that STMicroelectronics’s MCUs solution are the de-facto standards platform to serve the IoT market which is in huge expansion nowadays." said Daniel Colona, Marketing Director, Microcontroller Division, STMicroelectronics.

Typical applications for this module include smart metering, wearables, tracking, M2M and internet of things (IoT) edge nodes. Accommodating a wide range of temperatures, the module can operate from – 40 to + 85 °C.

Mass production will commence in January 2017, data sheet and samples will be available since December 2016.
