Quick Start Guide: X-NUCLEO-OUT14A1
Industrial Digital Output Expansion Board based on ISO808A-1 for STM32 Nucleo
Hardware Overview
Hardware Description
The X-NUCLEO-OUT14A1 industrial digital output expansion board for STM32 Nucleo provides a powerful and flexible environment for evaluating the driving and diagnostic capabilities of the ISO808A-1. The ISO808A-1 is an Octal High Side Switch with embedded galvanic isolation, 20 MHz SPI, overtemperature and Power Good diagnostics, and high inductive load driving capability. It is designed for digital output modules connected to industrial loads up to 1.0 A (max. per channel).
The X-NUCLEO-OUT14A1 interfaces directly with the microcontroller on the STM32 Nucleo via the Arduino UNO R3 connectors (default configuration) and ST morpho connectors (optional, not mounted). The galvanic isolation between the logic side and the process side of the system is guaranteed by the 2k VRMS isolation embedded in the ISO808A-1. The expansion board can be connected to either a NUCLEO-F401RE or a NUCLEO-G431RB development board.
It is also possible to evaluate a system composed of two stacked X-NUCLEO-OUT14A1 boards, enabling supported daisy chaining, or systems combining the X-NUCLEO-OUT14A1 with other expansion boards, provided the compatibility with signals mapped on Arduino connectors.
Main Features:
- A single expansion board allows evaluation of an octal-channel digital output module with 1.0 A (max.) per-channel capability.
- Operating range up to 36 V / 8.0 A.
- Low power dissipation (RON(MAX) = 260 mΩ).
- Fast decay for high inductive loads.
- 20MHz SPI Control mode.
- Output enable signal.
- Under-voltage lock-out.
- Overload and over-temperature protections.

STM32 ODE Ecosystem
FAST, AFFORDABLE PROTOTYPING AND DEVELOPMENT
The STM32 Open Development Environment (ODE) is an open, flexible, easy, and affordable way to develop innovative devices and applications based on the STM32 32-bit microcontroller family, combined with other state-of-the-art ST components connected via expansion boards. It enables fast prototyping with leading-edge components that can quickly be transformed into final designs.
The STM32 ODE includes the following five elements:
- STM32 Nucleo development boards: A comprehensive range of affordable development boards for all STM32 microcontroller series, with unlimited unified expansion capability, and with integrated debugger/programmer.
- STM32 Nucleo expansion boards (X-NUCLEO): Boards with additional functionality to add sensing, control, connectivity, power, audio, or other functions as needed. The expansion boards are plugged on top of the STM32 Nucleo development boards. More complex functionalities can be achieved by stacking additional expansion boards.
- STM32Cube software: A set of free-of-charge tools and embedded software bricks to enable fast and easy development on the STM32, including a Hardware Abstraction Layer, middleware, and the STM32CubeMX PC-based configurator and code generator.
- STM32Cube expansion software (X-CUBE): Expansion software provided free of charge for use with STM32 Nucleo expansion boards, and compatible with the STM32Cube software framework.
- STM32Cube Function Packs: Set of function examples for some of the most common application cases, built by leveraging the modularity and interoperability of STM32 Nucleo development boards and expansions, with STM32Cube software and expansions.
The STM32 Open Development Environment is compatible with a number of IDEs, including IAR EWARM, Keil MDK, mbed, and GCC-based environments.
