Getting started with the STEVAL-ST25R3916B kit based on the ST25R3916B
Introduction
The
STEVAL-25R3916B
is a ready-to-use kit based on the
contactless applications. The kit allows evaluating this device features and functionality in the reader/writer, peer to peer, and
card emulation modes.
The kit consists of:
•
a microprocessor main board (STEVAL-M25R16B), which includes hardware and software tools that enable using the
entire STM32 ecosystem. This board is powered through USB connectors
•
a reader expansion board (STEVAL-D25R16B), which embeds the
PCB with its tuning circuit
The communication link between the two boards is the SPI bus. The processor card provides the power. Specific data lines
complete the pin connector assignment shared between the cards.
Thanks to several demonstrations that can be performed, this kit helps the users develop and test their applications.
The kit is FCC certified, with FCC ID: YCPR3916BD1. It is also IC certified, with IC: 8976A-R3916BD1; PMN:
STEVAL-25R3916B; HVIN: STEVAL-25R3916B.
UM3033 - Rev 1 - February 2023
