STM32L082 LoRa Module

Added to your shopping cart

Murata Type ABZ LoRa Modules are compact low power wide area network (LPWAN) wireless modules that support the LoRaWAN long range wireless protocol. The module measures just 12.5x11.6x1.76 mm and are housed in metal shielded packages. The modules include a Semtech SX1276 ultralong range spread spectrum wireless transceiver and an STMicro STM32L0 series ARM Cortex M0+ 32 bit microcontroller (MCU).

Murata has joined the LoRa Alliance™, a non-profit association of members who believe that the Internet of Things era is now. Murata has worked to design a cost-effective, small form factor LoRaWAN module capable of supporting a wide range of sensors. This new wireless module should help increase the adoption of the LoRaWAN platform worldwide and make it the standard for LPWANs supporting low power IoT applications.

  • Integrated TCXO with robust low drift thermal characteristics provides an accurate clock source for the RF transceiver
  • An ADC and up to 18 GPIOs provide plenty of flexibility for connecting sensors, switches and status LEDs
  • Pre-certified radio regulatory approvals for operating in the 868 and 915MHz industrial, scientific and medical (ISM) spectrum in most geographical regions of the world
  • The module is powered from a 2.2 to 3.6VDC supply
  • MCU includes 192kB flash and 20kB RAM
  • Normal output power is +14dBm but a PA boost function can be selected to increase RF output to + 20dBm for long range applications
  • Communication with the module can be achieved via UART, SPI, or I2C peripheral interfaces
  • Optional STSAFE secure element can be incorporated into the MCU to enhance the network security capabilities
  • Operating Temperature: -40 + 85°C
