Description
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).
