Getting started with X-NUCLEO-OUT03A1 industrial digital output expansion board for STM32 Nucleo
Introduction
The X-NUCLEO-OUT03A1 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 IPS2050H (dual high-side smart power solid state relay) in a digital output module connected to 2.5 A (max.) industrial loads.
The X-NUCLEO-OUT03A1 interfaces with the microcontroller on the STM32 Nucleo via 5 kV optocouplers driven by GPIO pins , Arduino UNO R3 (default configuration) and ST morpho (optional, not mounted) 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-OUT03A1 expansion boards.
As an example, a system with four X-NUCLEO-OUT03A1 expansion boards allows you to evaluate an eight-channel digital output module with 2.5 A (max.) capability each.

The X-NUCLEO-OUT03A1 embeds the IPS2050H 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 optical isolation implemented through four optocouplers (ISO1, ISO2,
ISO3 and ISO4) for signal forward to the device and FLT pins for feedback diagnostic signals.
• Based on IPS2050H dual high-side switch, which features:
– Operating range up to 60 V/2.5 A
– Low power dissipation (R
ON(MAX)
= 50 mΩ)
– Fast decay for inductive loads
– Smart driving of capacitive load
– Under-voltage lock-out
– Per-channel overload and over-temperature protection
– PSSO24 package
Application board operating range: 8 to 33 V/0 to 2.5 A
Extended voltage operating range (J3 open) up to 60 V
Green LEDs for output on/off status
Red LEDs for per-channel diagnostic (overload and overheating)
5 kV galvanic isolation
Supply rail reverse polarity protection
EMC compliance with IEC61000-4-2, IEC61000-4-3, IEC61000-4-5
Compatible with STM32 Nucleo development boards
Equipped with Arduino UNO R3 connectors
CE certified
RoHS and China RoHS compliant

Overview
Digital section
The digital section is associated with the STM32 interface and digital supply voltage to and from the X-NUCLEO-
OUT03A1 expansion board.
Figure 2. X-NUCLEO-OUT03A1 expansion board: digital interface components
UM2727 - Rev 1
The four Arduino UNO R3 connectors:
• allow expansion board communication with the
STM32 peripheral and GPIO resources;
STM32 Nucleo development board microcontroller accessing
• provide digital supply voltage between the STM32 Nucleo development board and the X-NUCLEO-
OUT03A1 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 CN2 connector (not mounted by default) on the expansion board and the ground loop should be closed by mounting D2 (enable the reverse polarity protection) or by closing J17 (without reverse polarity).
•
•
To supply the V
IN
voltage rail 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
G431RB
NUCLEOpage 3/15

Power section
The power section involves the power supply voltage (CN1, pin 2 and 3 for V
CC
, pin 4 for GND), load connection
(between CN1 pins 1-4 and CN1 pins 5-4) and electromagnetic compatibility (EMC) protection.

For EMC:
• The SM15T39CA transient voltage suppressor (TR1), enabled by closing JP3, is placed between V
CC
and
GND tracks to protect the IPS2050H against surge discharge on the supply rail path up to ±1kV/2Ω coupling;
•
• in common mode surge testing, two single-layer capacitors (C1 and C2 - not included) must be soldered at the predisposed locations; the IPS2050H output stages do not require additional EMC protections with respect to the IEC61000-4-2,
IEC61000-4-3, IEC61000-4-5 standards.

Multiple board configuration
It is also possible to evaluate an eight channel digital output module by stacking four X-NUCLEO-OUT03A1 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 four resistors for each board from the default position and solder them back in the alternate positions according to the following table.
