Type ABZ is a new, compact, low cost, low power wide area network (LPWAN) wireless module that supports the LoRaWAN long range wireless protocol. This new stand-alone module measures just 12.5 x 11.6 x 1.76 mm, 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 that has robust low drift thermal characteristics provides an accurate clock source for the RF transceiver.
