TypeABZ-104 is a new LoRa modem module embedding Semtech modem firmware integrating the LoRaWAN protocol stack and device-management features including security keys.

This new stand-alone module measure just 12.5 x 11.6 x 1.76mm, 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 RF transceiver.

Communication with the module can be achieved via UART, and the module is powered from a 2.2 to 3.6 VDC supply. TypeABZ-104 has pre-certified radio regulatory approvals for operating in 868 and 915MHz industrial, scientific and medical (ISM) spectrum in most geographical regions of the world.

The normal output power is +14dBm but a PA boost function can be selected to increase RF output to +18.5dBm for long-range application or those where the end -device is sited in a poor signal location indoors.

Typical applications for this module includes smart metering, wearables, tracking, M2M and internet of things (IoT) edge nodes. Accomodating a wide range of temperature
