Industrial sensors The kit consists of the STEVAL-IOD004V1 main board (not available for sale), the STLINK-V3MINI programmer and debugger tool, a 14-pin flat cable, and an M8 to M12 standard industrial connector adapter. The kit acts as a modern smart industrial sensor to be connected to a master IO-Link hub (or a suitable PLC interface). The power supply for the MCU, sensors, and other logic devices derives from the DC-DC converter controller embedded in the L6364W. The on-board STM32G071EB microcontroller runs an IO-Link demo stack v.1.1, which controls the IO-Link communication, and the software code that manages the L6364W transceiver and the MEMS industrial sensors.

Connect the main board to an IO-Link master via the adapter and the M8 connector included in the kit for normal operation. Connect the same board to the STLINKV3MINI through the flat cable only if you want to program the STM32G071EB with a new firmware.

The main board (STEVAL-IOD004V1) has been designed with few ICs. Taking this into consideration, smartsensing applications can benefit from the L6364W dual-channel transceiver. For example, the ISM330DHCX inertial module can monitor a robotic arm (for vibration and compensation) while the IIS2MDC can detect the magnetic field, providing a warning along the supplementary channel.
