SP1ML-868 (STMICROELECTRONICS)

The SP1ML-868 from STMicroelectronics is a 868MHz SPIRIT1 antenna module (region 1, Europe). This ultra-low power and fully integrated RF module operates in 868MHz SRD bands. The SP1ML integrates an on-board antenna with easy to use interface, allowing users to easily add wireless connectivity in designs without requiring in depth RF experience and reducing time to market. It is based on SPIRIT1 RF sub-GHz transceiver (with integrated SMPS), STM32L1 microcontroller, integrated filter/balun and chip antenna. The UART host interface allows simple connection to an external microcontroller with a standard firmware, allowing AT commands to facilitate RF configuration, data transmission and reception using simple point to point communication. Selected STM32L1 GPIO and peripherals are available for interfacing to external devices in user application. The SP1ML can be used as an open platform, replacing default firmware with its own application firmware.
