STEVAL-IOD04KT1The tiny dimensions of the main board have been achieved thanks to the small sizesof the CSP package options of L6364W and STM32G071EB.Connect the main board to an IO-Link master via the adapter and the M8 connectorincluded 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 anew firmware.DB4571 - Rev 2page 2/10

STEVAL-IOD04KT1Solution overview1Solution overviewThis reference design targets IO-Link based applications, that is, smart industrial sensors that feature easyconfiguration, remote monitoring, reduced wiring, advanced diagnostics, and easy device replacement.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 ISM330DHCXinertial module can monitor a robotic arm (for vibration and compensation) while the IIS2MDC can detect themagnetic field, providing a warning along the supplementary channel.Figure 1.
