Description
The SP1ML-868 and SP1ML-915 are low power RF modules based on the SPIRIT1 radio,
with integrated voltage regulation, antenna, crystal and microcontroller in a compact
surface mount module form-factor. The module allows OEMs to easily add wireless
capability to any electronic device without requiring in-depth RF experience, and has the
necessary FCC modular approvals and CE compliance to reduce time to market.
The UART host interface allows simple connection to an external microcontroller. Access
to module features is provided through an extended AT command set. A simple cable
replacement model allows the module to be used similarly to a standard serial interface.
The microcontroller serial wire debug signals are available and allow the standard
firmware to be replaced by a user application, enabling use as a wireless application
module where no external microprocessor system is required. Select STM32L GPIO and
peripherals are available for interfacing to external devices in the user application, and
advanced features of the SPIRIT1 radio are also accessible.
