STMicroelectronics UM2866 X-NUCLEO-OUT06A1 Industrial Digital Output Expansion Board 

Getting started with X-NUCLEO-OUT06A1 industrial digital output expansion board for STM32 Nucleo

Introduction

The X-NUCLEO-OUT06A1 industrial digital output expansion board for STM32 Nucleo provides a powerful and flexible environment for the evaluation of the driving and diagnostic capabilities of the IPS1025H-32 single high-side smart power solid state relay, in a digital output module connected to 5.7 A industrial loads.
The X-NUCLEO-OUT06A1 interfaces with the microcontroller on the STM32 Nucleo via 5 kV optocouplers driven by GPIO pins and Arduino UNO R3 connectors.
The expansion board can be connected to either a NUCLEO-F401RE or NUCLEO-G431RB development board.
It is also possible to evaluate a system composed by up to four stacked X-NUCLEO-OUT06A1 expansion boards.
As an example, a system with four X-NUCLEO-OUT06A1 expansion boards allows you to evaluate a quad channel digital output module.

Overview

The X-NUCLEO-OUT06A1 embeds the IPS1025H-32 intelligent power switch (IPS), featuring overcurrent and overtemperature protection for safe output load control.
The board is designed to meet application requirements in terms of galvanic isolation between user and power interfaces. This requirement is satisfied by an optical isolation implemented through three optocouplers (ISO1, ISO2, and ISO3) for signal forward to the device and FLT pins for feedback diagnostic signals.
The expansion board features:

• Based on IPS1025H-32 single high-side switch, which features:
  • Operating range up to 60 V
  • Low power dissipation (RON(MAX) = 25 mΩ)
  • Fast decay for inductive loads
  • Smart driving of capacitive load
  • Under-voltage lock-out
  • Overload and over-temperature protection
  • PSSO24 package
• Application board operating range: 8 to 33 V/0 to 5.7 A
• Extended voltage operating range (J3 open) up to 60 V
• Green LED for output on/off status
• Red LEDs for diagnostics (overload and overheating)
• 5 kV galvanic isolation Supply rail reverse polarity protection
• EMC compliance with IEC61000-4-2, IEC61000-4-3, IEC61000-4-4, IEC61000-4-5, IEC61000-4-8
• Compatible with STM32 Nucleo development boards
• Equipped with Arduino UNO R3 connectors
• CE certified:
  • EN 55032:2015 + A1:2020
  • EN 55035:2017 + A11:2020
• RoHS and China RoHS compliant

Digital section
The digital section is associated with the STM32 interface and digital supply voltage to and from the X-NUCLEO-OUT06A1 expansion board.

Figure 2. X-NUCLEO-OUT06A1 expansion board: digital interface section
The dotted green line indicates the whole digital interface section. Pink rectangles identify Arduino UNO R3 connectors.

The four Arduino UNO R3 connectors:

• allow expansion board communication with the STM32 Nucleo development board microcontroller accessing STM32 peripheral and GPIO resources;
• provide digital supply voltage between the STM32 Nucleo development board and the X-NUCLEO-OUT06A1 expansion board, in either direction.Normally, the STM32 Nucleo development board supplies the expansion board by a 3v3 or 5v0 generated by the USB. You can select the preferred voltage on the expansion board via SW3 (3v3 closing pins 1-2; 5v0 closing pins 2-3).
  Alternatively, it is possible to supply the STM32 Nucleo development board by the expansion board. In this case, an external supply voltage (7-12 V) should be connected to the CN2 connector (not mounted by default) on the expansion board and the ground loop should be closed by mounting D2 (enabling the reverse polarity protection) or by closing J2 (without reverse polarity).
  To supply the VIN voltage rail, it is necessary to:
• close jumper JP5 between pins 2 and 3 and open jumper JP1 on the NUCLEO-F401RE;
• open jumper JP5 between pins 1 and 2 and close jumper JP5 between pins 3 and 4 on the NUCLEO-G431RB.

Power section

The power section involves the power supply voltage (CN1, pins 4 and 5 for VCC, pin 3 for GND), load connection (a load can be connected between pins CN1.1 and CN1.3 or CN1.2 and CN1.3; both output pins are connected to the single output channel as shown in Section 2 Schematic diagrams) and electromagnetic compatibility (EMC) protection.

For EMC

• The SM15T39CA transient voltage suppressor (TR1), enabled by closing J3, is placed between VCC and GND tracks to protect the IPS1025H-32 against surge discharge on the supply rail path up to ±1 kV/2 Ω coupling;
• in common mode surge testing, two single-layer capacitors (C1 and C2 – not included) must be soldered at the predisposed locations;
• the IPS1025H-32 output stages do not require additional EMC protections with respect to the IEC61000-4-2, IEC61000-4-3, IEC61000-4-4, IEC61000-4-5, IEC61000-4-8 standards.

Hardware requirements
The X-NUCLEO-OUT06A1 expansion board is designed to be used with the NUCLEO-F401RE or NUCLEO-G431RB STM32 Nucleo development boards.
To function correctly, the X-NUCLEO-OUT06A1 must be plugged onto the matching Arduino UNO R3 connector pins on the STM32 Nucleo board as shown below.

System requirements
To use the STM32 Nucleo development boards with the X-NUCLEO-OUT06A1 expansion board, you need:

• Windows PC/laptop (Windows 7 or above)
• type A to mini-B USB cable to connect the STM32 Nucleo board to the PC when using a NUCLEO-F401RE development board
• type A to micro-B USB cable to connect the STM32 Nucleo board to the PC when using a NUCLEO-G431RB development board
• the X-CUBE-OUT5 firmware and software package installed on your PC/laptop

Board setup

1. Step. Connect the micro-USB or mini/USB cable to your PC to use the X-NUCLEO-OUT06A1 with NUCLEO-F401RE or NUCLEO-G431RB development board
2. Step. Download the firmware (.bin) onto the STM32 Nucleo development board microcontroller through STM32 ST-LINK utility, STM32CubeProgrammer and according to your IDE environment as detailed in the table below.

Step 3.Connect the IPS1025H-32 device supply voltage via CN1 (see Section 1.1.2 Power section).
Step 4. Provide the digital supply voltage (see Section 1.1.1 Digital section).
Step 5. Connect the load on the output connector (see Section 1.1.2 Power section).
Step 6. Reset the example sequence using the black push button.
Step 7. Push the STM32 Nucleo blue button to select the example provided in the firmware package.

Multiple board configuration
It is also possible to evaluate a four channel digital output module by stacking four X-NUCLEO-OUT06A1 with shared or independent supply rail and independent loads.
In this case, the four expansion boards (board 0, 1, 2, 3 as shown in the table below) must be properly configured: for board 1, 2 and 3, it is necessary to unsolder three resistors for each board from the default position and solder them back in the alternate positions according to the following table.
