The module supports 18 GPIOs and includes a Semtech SX1276 ultralong range spread spectrum wireless transceiver with a STMicro STM32L0 series ARM Cortex®-M0+ 32 bit microcontroller, offering communication via UART, SPI, or I²C interfaces. The STM32L0 microcontroller includes 192 kBytes of flash and 20 kBytes of RAM, offering enough memory to embed user applications and host other modulation stacks. The microcontroller also offers an optional STSAFE secure element to enhance the network security capabilities.

The ABZ module features pre-certified radio regulatory approvals for operating in the 868 MHz and 915 MHz industrial, scientific and medical (ISM) spectrum in most geographical regions of the world. The device’s normal output power is +14 dBm but a PA boost function can be selected to increase radio frequency (RF) output to + 20 dBm for long-range applications. The module also integrates a temperature-compensated crystal oscillator (TCXO) with robust low-drift thermal characteristics to provide an accurate clock source for the Semtech transceiver. The module measures 12.5 × 11.6 × 1.76 mm and is housed in a metal shielded package.
