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

sp1ml-868和sp1ml-915是超低功耗、全集成射频模块在868 MHz和915 MHz系统分别运行ISM频带。

sp1ml模块是一个紧凑型模块、车载天线具有易于使用的界面集成，允许用户方便地添加无线连接，而不需要深入的射频设计经验，并拥有所有必要的批准和CE符合FCC标准，减少进入市场的时间。

这些模块都是基于spirit1 sub-GHz收发器（RF集成开关电源），stm32l1单片机、集成滤波器、巴伦和芯片天线。UART接口允许简单的连接到一个标准的固件外部微控制器，允许在命令方便射频配置、数据传输和接收，使用简单的点对点通信。选择stm32l1 GPIO外设可以连接到外部设备在用户中的应用。该spirit1无线电高级功能也可。串行线调试接口（SWD）也可。

该模块是CE认证和FCC认证（FCC ID s9nsp1ml）。
