STMicroelectronics Development Kit

The STMicroelectronics development kit is an RF discovery kit featuring the CMWX1ZZABZ-091 LoRa module from Murata. This module incorporates the SX1276 low-power transceiver, which features a long-range modem. This module supports high performance and OOK/FSK modulations. The transceiver is controlled by a STM32L072CZY6 microcontroller embedded in the module. This kit provides support for bi-directional end devices in class A and class C protocols and for end device activation, either via Over-The-Air Activation (OTAA) or via Activation-By-Personalization (ABP).
