STMicroelectronics UM3184 Industrial Digital Output Expansion Board User Manual
Introduction
The X-NUCLEO-OUT01A2 is an industrial digital output expansion board for STM32 Nucleo. It provides a powerful and flexible environment for the evaluation of the driving and diagnostic capabilities of the ISO8200BQ octal high-side smart power solid state relay, with embedded galvanic isolation, in a digital output module connected to 0.7 A industrial loads.
The X-NUCLEO-OUT01A2 directly interfaces with the microcontroller on the STM32 Nucleo driven by GPIO pins and Arduino® R3 connectors.
The galvanic isolation between the microcontroller and the process stage is guaranteed by the ISO8200BQ.
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 a X-NUCLEO-OUT01A2 stacked on other expansion boards.
The board can be configured as the former X-NUCLEO-OUT01A1 by a set of jumpers (open: J13, J14, J15,J16, J17) and switches (close 1-2: SW1, SW28, SW29, SW30, SW31, SW32, SW33, SW35, SW37). In this case, the driving firmware can be only the X-CUBE-OUT1 and the board can be connected to the X-NUCLEO-PLC01A1 to form a powerful industrial PLC with 8 inputs and 16 outputs. Also, wireless communication capabilities can be added with the X-NUCLEO IDW01M1, which establishes communication on a smart device to manage the PLC remotely. A dedicated ST-PLC app is available for Android™ and iOS™ systems for this purpose.

Getting started
Overview
The X-NUCLEO-OUT01A2 embeds the ISO8200BQ intelligent power switch (IPS), which features galvanic isolation, overcurrent and overtemperature protection for safe output loads control.
The board is designed to meet the application requirements for the galvanic isolation between the user and power interfaces.
The galvanic isolation embedded by the ISO8200BQ satisfies this requirement, avoiding the necessity of external comptrollers, with a consequent cost saving and a reduced application size.

Digital section
The digital section is associated with the STM32 interface and the digital supply voltage to and from the XNUCLEO-OUT01A2 expansion board.
Figure 2. X-NUCLEO-OUT01A2 expansion board: digital interface section
The dotted green line indicates the whole digital interface section. The pink rectangles identify the Arduino® UNO R3 connectors.
The four Arduino® UNO R3 connectors:
- allow the expansion board to communicate with the STM32 Nucleo development microcontroller board accessing the STM32 peripheral and GPIO resources;
- provide the digital supply voltage between the STM32 Nucleo development board and the X NUCLEOOUT01A2 expansion board, in either direction
Usually, the STM32 Nucleo development board supplies the expansion board by a 3.3 V or 5.0 V generated by the USB.
Alternatively, it is possible to supply the STM32 Nucleo development board from the expansion board. In this case, an external supply voltage (7-12 V) should be connected to the CN11 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 J5 (without reverse polarity). In this scenario, the logic side of the ISO8200BQ can be supplied by the 3.3 V supply rail generated by the expansion board: in this case, on the X-NUCLEO OUT01A2, J4 must be closed between pins 5 and 6.
To supply the VIN voltage rail, it is necessary to:
- close the JP5 jumper between pins 2 and 3 and open the JP1 jumper on the NUCLEO-F401RE;
- open the JP5 jumper between pins 1 and 2 and close the JP5 jumper between pins 3 and 4 on the NUCLEO-G431RB.
The pin 3 of the connector CN11 can be used to supply the logic side of the ISO8200BQ independently by the expansion board. In this case, on the X-NUCLEO-OUT01A2, the pins 1 and 2 of J4 must be closed (pins 5-6 open).
Power section
The power section involves the power supply voltage (CN1, pin 1 for VCC, pin 2 for GND), the load connection (eight loads can be connected between each pin of CN2, CN3, CN4, and CN12 and pin 2 of CN1), EMC protections (U2), and supply reverse polarity protection (D1)
Figure 3. X-NUCLEO-OUT01A2 expansion board: power section
- ISO8200BQ
- Output and power supply connector
- Output channels – green LEDs
- Status (overtemperature) red LED
- Output Enable yellow LED
For EMC:
- the SM15T39CA transient voltage suppressor (U2), enabled by closing J9, is placed between VCC and GND tracks to protect the ISO8200BQ against surge discharge on the supply rail path up to ±1 kV/2 Ω coupling;
- in the common mode surge testing, two single-layer capacitors (C11 and C12 – not included) must be soldered at the predisposed locations;
- the ISO8200BQ 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.
The EMC performance of the X-NUCLEO-OUT01A2 is detailed below:
- for emission (when the DC input port of the board is powered by an AC-DC, DC-DC or battery with a cable that does not exceed a three-meter length), compliance with standards:
- EN IEC 61000-6-3:2021
- EN 55032:2015 +A1:2020
- for immunity, compliance with standards:
- EN IEC 61000-6-1:2019
- EN 55035:2017 +A11:2020
Hardware requirements
The X-NUCLEO-OUT01A2 expansion board is designed to be used with the NUCLEO-F401RE or NUCLEOG431RB STM32 Nucleo development boards.

System requirements
To use the STM32 Nucleo development boards with the X-NUCLEO-OUT01A2 expansion board, you need:
- a Windows PC/laptop (Windows 7 or above)
- a type A to mini-B USB cable to connect the STM32 Nucleo board to the PC when using a NUCLEOF401RE development board
- a type A to micro-B USB cable to connect the STM32 Nucleo board to the PC when using a NUCLEOG431RB development board
- the X-CUBE-IPS firmware and software package installed on your PC/laptop
Board setup
If the board is configured as X-NUCLEO-OUT01A1, refer to UM2209 and X-CUBE-OUT1 as the control firmware. When the board is configured as X-NUCLEO-OUT01A2, refer to the following steps:
Step 1. Connect the mini-USB or micro-USB cable to your PC to use the X-NUCLEO-OUT01A2 with NUCLEOF401RE or NUCLEO-G431RB development board
Step 2. Download the firmware (.bin) provided with the X-CUBE-IPS software package as detailed in Table 4. The X-NUCLEO-OUT01A2 must be configured coherently to the selected control mode for ISO8200BQ through SW37 and SW36. These switches define the level of ISO_DRV signal: according to the level of this signal (high or low), the firmware will properly manage respectively the synchronous or the direct control mode.
