The STMicroelectronics Expansion board for STM32 Nucleo provides a powerful and flexible environment for the evaluation of the driving and diagnostic capabilities. It offers two different application sides electrically separated by the 2.8 kVRMS galvanic isolation featured by the digital isolators. The logic side is the application side where the MCU operates.

Operating voltage range 10.5 to 36 V
Operating current range less than equal to 1 A per channel
Low power dissipation
Can drive resistive capacitive and inductive loads
Under voltage shutdown with hysteresis
Per channel open drain thermal fault diagnostic pins
