Product details

Overview

X-NUCLEO-OUT12A1 from STMicroelectronics is an industrial digital output expansion board for STM32 Nucleo development platforms, built around the ISO808A octal high-side smart power switch. It delivers galvanically isolated 0.7 A per channel switching (9.2–36 V process side), 20 MHz SPI daisy-chain control, and integrated diagnostics including PGOOD, FAULT, and thermal monitoring - enabling evaluation of solid-state relay behavior in PLC I/O modules.

For engineers reviewing the X-NUCLEO-OUT12A1 datasheet, X-NUCLEO-OUT12A1 pinout, X-NUCLEO-OUT12A1 application, or X-NUCLEO-OUT12A1 equivalent, this board supports rapid validation of isolated digital output architecture, SPI-controlled load driving, fault reporting across stacked boards, and compatibility with Arduino® UNO R3 and STM32 Nucleo (NUCLEO-F401RE/NUCLEO-G431RB) interfaces.

Technical Context

The board implements a galvanically isolated digital output stage using the ISO808A, which integrates eight independent high-side switches with embedded 2 kVRMS isolation, fast decay for inductive loads, and comprehensive protection (undervoltage lock-out, overload, overtemperature, loss-of-ground). Logic-side interface operates at 3.3–5 V, while process-side supply is configurable from 10 V (J10 open) to 36 V (J9 open).

SPI communication runs up to 20 MHz with daisy-chain capability across two boards for 16-channel expansion. On-board LED indicators provide real-time status for output enable (yellow), PGOOD (red), common fault (red), and individual channel on/off (green), all mapped to configurable jumpers (J3, J6, J7).

FAQ

What microcontrollers is the X-NUCLEO-OUT12A1 compatible with?

The board is natively compatible with STM32 Nucleo development boards including NUCLEO-F401RE and NUCLEO-G431RB, interfacing via Arduino® UNO R3 and Morpho headers. It requires no external level-shifting for 3.3 V or 5 V logic-side operation and supports direct GPIO/SPI connection to any STM32 MCU with matching pinout and voltage tolerance.

How does daisy-chaining work between two X-NUCLEO-OUT12A1 boards?

Daisy-chaining uses the SPI_SS, SPI_MOSI, SPI_MISO, SPI_CLK, and DaisyChain signals routed between CN7 and CN10 connectors. The first board drives the second via its SDO output connected to the second board's SDI input, enabling single-SPI-master control of 16 isolated outputs with synchronized fault reporting and PGOOD monitoring across both boards.

What protections does the ISO808A provide on the X-NUCLEO-OUT12A1?

The ISO808A delivers undervoltage lock-out (VCC < 4.5 V disables outputs), overtemperature shutdown (>150 °C), overload current limiting, and loss-of-ground detection. These are hardware-enforced protections reflected on the FAULT pin and red STATUS LED, independent of firmware - ensuring fail-safe behavior during industrial transients or wiring faults.

Can the X-NUCLEO-OUT12A1 drive inductive loads like solenoids or relays?

Yes - the ISO808A includes active fast-decay circuitry that safely commutates stored energy in inductive loads, preventing voltage spikes above 40 V. This allows direct driving of 24 V DC solenoids, contactor coils, and industrial relays without external flyback diodes or snubbers, verified per IEC 61000-4-4 and IEC 61000-4-5 immunity requirements.
