STMicroelectronics STEVAL-IDP004V2 Evaluation Board embeds the STM32F205RB microcontroller and four separate L6360 ICs. Communication with the ICs is implemented via I2C in master mode and is managed by the STM32F205RB MCU. Each L6360 has its own address and shares the bus with the other devices. The STEVAL-IDP004V2 is developed to create a multi-port master based on serial asynchronous communication to support the IO-Link protocol. Each node is equipped with an industrial M12 connector (as recommended by the standard) for connection with a single slave node using a cable (max. length 20m). The wire is a normal three-pole: one for the IO-Link bus, one for the L+ line (positive supply voltage pole), and one for the L- line (negative supply voltage pole). The STEVAL-IDP004V2 board also includes RS-485 bus, CAN bus, and USB hardware interfaces. The layout is designed to meet the requirements for IEC61000-4-2/4/5 for the industrial segment.
