Dual-channel IO-Link reference design based on L6364Q and STM32L051

The STDES-IOD002V1 is a reference design board for a dual channel IO-Link device mounting the L6364Q transceiver, the STM32L051T8Y6TR microcontroller running STSW-IOD02L051, a 7-pin programming connector and a 10-pin expansion connector.

The STDES-IOD002V1 compact size allows achieving high EMC immunity levels and makes the application suitable for the harsh industrial environments.
Thanks to a set of configurable drop jumpers and switches, combined with the source code of the STSW-IOD02L051, different configurations are possible.
The microcontroller can be programmed by a dedicated SWD 7-pin connector.
A 10-pin expansion connector allows the STDES-IOD002V1 to host external sensors with I2C control interface and up to two interrupts (e.g., IIS2MDC or ISM330DHCX).
The on-board push button is used to test the CQ line or to control the DIO line via the CTLD pin.
