Product overview


The STEVAL-IOD002V1 expansion board for STM32 Nucleo is based on the L6364W dual channel SIO and IO-Link PHY device transceiver embedding 50 mA 3.3 V and 5.0 V voltage regulators, DC-DC converter and M-sequence management.

The expansion board provides an affordable and easy-to-use solution for the development of SIO and IO-Link industrial sensor applications, letting you easily evaluate the L6364W communication features and robustness.

The STEVAL-IOD002V1 communicates with the STM32 controller via SPI and GPIO pins and it is compatible with the Arduino UNO R3 (default configuration) and ST morpho (optional, not mounted) connectors (when connected to a NUCLEO-L073RZ or NUCLEO-G071RB development board).

Communication via IO-Link can be performed in either Multi-byte and Single-byte modes with SPI control of IC configuration and bidirectional sensor data transmission, or in Transparent mode with SPI control of IC configuration and UART interfacing for bidirectional sensor data transmission.

The switches on the STEVAL-IOD002V1 conveniently allow you to configure L6364W and expansion board settings such as transmission mode and DC-DC converter enable/disable according to application requirements.

You can also perform evaluation of comprehensive industrial sensor modules by connecting the STEVAL-IOD002V1 to the X-NUCLEO-IKS02A1 sensor shield.
