Product overview
Description
The main objective of the ST67W611M1 reference designs, STDES-67W61BU-U5 (B and U versions, with STM32U5), STDES-67W61P1-U5 (P version, single antenna, with STM32U5), and STDES-67W61P2-U5 (P version with antenna diversity, with STM32U5), is to recommend layouts and associated BOMs for dedicated applications (these boards are not for sale).
The other objective is to show the good coexistence of the ST67W611M1 coprocessor module with the STM32U575AI host microcontroller in a small board form factor. Performance has been assessed and FCC and CE certification checks have been done by an independent test laboratory.
These reference designs can be manufactured from files available for download from the www.st.com website. The access to all GPIOs allows the prototyping of a complete application. Sensitive layout parts can be extracted and pasted in any user board design with the same PCB characteristics and feature set.
Utilizing the reference designs for user applications helps achieve suitable RF performance and aids in passing certification.
