STMicroelectronics X-NUCLEO-OUT05A1

Overview

X-NUCLEO-OUT05A1 from STMicroelectronics is an industrial digital output expansion board for STM32 Nucleo platforms, built around the IPS1025H single high-side smart power switch. It delivers up to 2.5 A at 8–33 V (extendable to 60 V with J3 open), features 5 kV galvanic isolation via optocouplers, and provides real-time diagnostics via green (output status) and red (overload/overtemperature) LEDs.

For engineers reviewing the X-NUCLEO-OUT05A1 datasheet, X-NUCLEO-OUT05A1 pinout, X-NUCLEO-OUT05A1 application, or X-NUCLEO-OUT05A1 equivalent, this board supports rapid evaluation of high-side switching performance, fault diagnostics, and multi-board stacking for quad-channel digital output systems in PLC and industrial I/O designs.

Technical Context

The board interfaces with STM32 Nucleo microcontrollers (e.g., NUCLEO-F401RE, NUCLEO-G431RB) via GPIO-driven 5 kV optocouplers (TLP383) and Arduino UNO R3 connectors. Control signals are isolated, while load-side power is supplied independently (8–60 V).

It implements full protection logic including under-voltage lock-out, thermal shutdown, and overload detection-mirroring the IPS1025H's embedded safety architecture-and complies with IEC61000-4-x EMC standards for industrial environments.

FAQ

What microcontroller boards is the X-NUCLEO-OUT05A1 compatible with?

The board is natively compatible with STM32 Nucleo development boards featuring Arduino UNO R3 and ST morpho headers-including NUCLEO-F401RE and NUCLEO-G431RB. It requires no additional level-shifting or adapter hardware and communicates via isolated GPIO signals routed through TLP383 optocouplers.

How does the board handle overcurrent and thermal faults?

Fault detection is implemented via the IPS1025H's internal protection circuitry, which triggers automatic current limiting and thermal shutdown. The board surfaces these events as separate red LED indicators (FLT1 for overload, FLT2 for overtemperature), enabling immediate visual diagnosis without host MCU polling.

Can multiple X-NUCLEO-OUT05A1 boards be used together?

Yes-up to four boards can be physically stacked using standard Arduino and morpho headers. Each retains independent control and diagnostics, allowing evaluation of a synchronized 4-channel industrial digital output module with shared power and isolated signal routing.

What is the purpose of jumper J3 on the board?

J3 configures the input voltage range: closed (default) limits VIN to 8–33 V for compatibility with standard Nucleo supply rails; open extends the operational range up to 60 V, enabling direct connection to higher-voltage industrial bus lines while preserving IPS1025H's full specification.
