SP1ML:SUB 1GHz MODULE

The SP1ML-868 and SP1ML-915 are ultra-low power & fully integrated RF modules operating respectively in the 868 MHz SRD and 915 MHz ISM bands.

The SP1ML module is a compact-size module, integrating 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 has all necessary FCC modular approvals and CE compliance, reducing time-to-market.

These modules are based on the 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 the user application. Advanced features of the SPIRIT1 radio are also accessible. The serial wire debug interface (SWD) is also available. The SP1ML can be used as an open platform, replacing the default firmware with its own application firmware.

The modules are CE compliant and FCC certified (FCC ID S9NSP1ML).
