July 24, 2019  Stephen Law

MURATA LoRa Module Type ABZ (CMWX1ZZABZ) compact, low cost, low power wide area network (LPWAN) wireless module supports the LoRaWAN long-range wireless protocol. This new stand-alone device measures 12.5 x 11.6 x 1.76mm and is constructed in a metal shielded package and comprises a Semtech SX1276 ultra-long range spread spectrum wireless transceiver and an STMicro STM32L0 series ARM Cortex-M0+ 32-bit microcontroller (MCU). An integrated TCXO with robust low drift thermal characteristics provides an accurate clock source for the RF transceiver Communication with the module can be achieved via UART, SPI, or I2C peripheral interfaces. An ADC and up to 18 GPIOs provide plenty of flexibility for connecting sensors, switches and status LEDs. Device is powered from a 2.2 to 3.6Vdc supply.
