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模塊是一個(gè)緊湊型模塊、車載天線具有易于使用的界面集成，允許用戶方便地添加無線連接，而不需要深入的射頻設(shè)計(jì)經(jīng)驗(yàn)，并擁有所有必要的批準(zhǔn)和CE符合FCC標(biāo)準(zhǔn)，減少進(jìn)入市場(chǎng)的時(shí)間。

這些模塊都是基于spirit1 sub-GHz收發(fā)器（RF集成開關(guān)電源），stm32l1單片機(jī)、集成濾波器、巴倫和芯片天線。UART接口允許簡單的連接到一個(gè)標(biāo)準(zhǔn)的固件外部微控制器，允許在命令方便射頻配置、數(shù)據(jù)傳輸和接收，使用簡單的點(diǎn)對(duì)點(diǎn)通信。選擇stm32l1 GPIO外設(shè)可以連接到外部設(shè)備在用戶中的應(yīng)用。該spirit1無線電高級(jí)功能也可。串行線調(diào)試接口（SWD）也可。

該模塊是CE認(rèn)證和FCC認(rèn)證（FCC ID s9nsp1ml）。
