Introduction
The X-NUCLEO-OUT02A1 industrial digital output expansion board for STM32 Nucleo is based on the ISO8200AQ galvanic
isolated octal high-side smart power solid state-relay.
It provides an affordable and easy-to-use solution for the development of 8-channel digital output modules, letting you easily
evaluate the ISO8200AQ communication and industrial load driving features.
The X-NUCLEO-OUT02A1 can be connected to a NUCLEO-F401RE, NUCLEO-F103RB or NUCLEO-F302R8 development
board via Arduino™ UNO R3 connectors.
You can also evaluate the 16-channel digital output modules by connecting two X-NUCLEO-OUT02A1 expansion boards and
activating the daisy chaining feature.
The X-NUCLEO-OUT02A1 interfaces with the STM32 controller via SPI and GPIO pins and is compatible with the Arduino™
UNO R3 (default configuration) and ST morpho (optional, not mounted) connectors.
Industrial PLC functionality with 8 inputs and 16 outputs can be added with the X-NUCLEO-PLC01A1 expansion board.

1.1 Overview
The X-NUCLEO-OUT02A1 expansion board features:
• Based on the ISO8200AQ whose main characteristics are:
– Embedded 4kV galvanic isolation
– Radio frequency communication between the logic and process sides for maximum noise immunity
– Very low power dissipation (R
ON(MAX)
= 220 mΩ)
– Fast decay for inductive loads
– 20 MHz SPI I/F on logic side
– VCC power good diagnostics
– Overload and overheating protections with thermal shutdown and diagnostics
– QFN-32L (9x11x1 mm) package
• 10.5 to 33 V operating voltage range
• Green LED (x8) for output on/off status
• Red LED for process supply power good fault
• Red LED for overload and overheating
• Supply reverse polarity protection
• EMC compliance according to IEC61000-4-2, IEC61000-4-3, IEC61000-4-5
• Compatible with STM32 Nucleo boards
• Equipped with Arduino™ UNO R3 connectors
• CE certified
• RoHS and China RoHS compliant
• WEEE compliant
The SPI interface and the embedded power good detection allow a deeper diagnostics, daisy chaining and less
MCU GPIO resources on the PLC logic stage.
Note: The X-NUCLEO-OUT02A1 offers a digital output solution: each output stage is managed at microcontroller level.
As the board has no input stage, no sensors can be connected to it.

Board setup
Step 1. Connect the micro-USB cable to the PC.
Step 2. Download the firmware version onto the microcontroller.
Step 3. Set the following jumper configurations on the STM32 Nucleo board:
– Close SB62 and SB63 jumpers
– Open SB13 and SB14 jumpers
Step 4. Connect the ISO8200AQ device supply voltage to the X-NUCLEO-OUT02A1 via J1.
Step 5. Provide the digital supply voltage.
– when connected to the PC: keep the micro-USB cable connected and close jumper JP5 on the
STM32 Nucleo board between pins 1 and 2.
– in standalone mode: provide a 7 to 12 V external supply via J2 on the X-NUCLEO- OUT02A1 and
close jumper JP5 on the STM32 Nucleo board between pins 2 and 3.
Step 6. Connect the load on the output connector.
Step 7. Run the STM32 and push the blue button on the STM32 Nucleo board to select the example provided
in the firmware package.

2 Hardware description and configuration
2.1 Digital section
The digital section is associated with the STM32 interface and digital supply voltage to and from the X-NUCLEO-
OUT02A1 expansion board.
Figure 3. X-NUCLEO-OUT02A1 expansion board: digital interface components
The four Arduino™ UNO R3 connectors:
• allow the ISO8200AQ communication with the STM32 Nucleo board microcontroller and access to the
STM32 peripheral and GPIO resources;
• provide digital supply voltage to/from the STM32 Nucleo development board and the X-NUCLEO-OUT02A1
expansion board.
To provide an external digital supply:
• close jumper JP5 between pins 2 and 3 on the STM32 Nucleo development board;
• connect a 7 to 12 V supply at screw connector J2 on the X-NUCLEO-OUT02A1 expansion board.

Figure 4. X-NUCLEO-OUT02A1 expansion board: power section components
For EMC:
• a Transil™ diode SMC30J30CA is placed on VCC track to protect the ISO8200AQ against surge discharge;
• for common mode surge testing, two single-layer capacitors (C1 and C3, not mounted) must be soldered;
• 22 nF capacitors are included on the output lines for burst disturbance filtering.
To supply the load, connect the supply voltage to the J1 2-way screw connector. The load is connected to the 8way output.
