Arduino Vision Shield Rev 1 - 03/03/2021
The included HM-01B0 camera module has been pre-configured to work with the OpenMV libraries
provided by Arduino. Based on the specific application requirements, the Portenta Vision Shield is
available in two configurations with either Ethernet or LoRa connectivity. Ethernet is designed for
integration of the Portenta into wired networks and providing high bandwidth. In situations requiring
long range operation at low bandwidth, LoRa connectivity is the way to go. The multicore processor of
the Portenta H7 makes embedded vision possible by minimising the data bandwidth required.
Note: The Portenta Vision Shield is available in two SKU, Ethernet (ASX00021) and LoRa (ASX00026)
1.1 Application examples
Thanks to the low power consumption of the Vision Shield, it is well suited for bringing machine learning
to a wide range of Industry 4.0 and IoT applications.
Industrial production: The included HM-01B0 camera along with the OpenMV libraries allows for quality
control of items within a manufacturing or packaging plant. The small footprint, low power consumption
and LoRa/Ethernet connectivity allows for the module to be deployed essentially anywhere so that
defects are identified quickly and removed from the production environment.
Predictive maintenance: The combination of machine vision and machine learning capabilities of the
Vision Shield and the Portenta H7 opens up possibilities for predictive maintenance based on subtle
differences in the visual representation of machinery. These capabilities are further enhanced with the
two MP34DT05 MEMS microphones included in the Vision Shield.
Surveillance: The Vision Shield is able to provide surveillance capabilities in areas with low WiFi
penetration (e.g. warehouse) and large areas (e.g. shopping centres). The OpenMV libraries enable the
Vision Shield to identify objects and alert the operator via LoRa while saving a snapshot on the microSD
storage slot.
1.2 Related Products
The Vision Shield is developed as an add-on shield that requires the Portenta H7.

Arduino Vision Shield Rev 1 - 03/03/2021
The Himax HM-01B0 Module is a very low power camera with 324x324 resolution and a maximum of 60FPS
depending on the operating mode. Video data is transferred over a configurable 8-bit interconnect with support
for frame and line synchronisation. The module delivered with the Vision Shield is the monochrome version.
Configuration is achieved via a I2C connection with the Portenta H7.
HM-01B0 offers very low power image acquisition and provides the possibility to perform motion detection
without main processor interaction. “Always-on” operation provides the ability to turn on the main processor
when movement is detected with minimal power consumption.
3.3 Digital Microphones
The dual MP34DT05 digital MEMS microphones are omnidirectional and operate via a capacitive sensing
element with a high (64 dB) signal to noise ratio. The microphones have been configured to provide separate
left and right audio over a single PDM stream.
The sensing element, capable of detecting acoustic waves, is manufactured using a specialized silicon
micromachining process dedicated to produce audio sensors
3.3 Micro SD Card Slot
A micro SD card slot is available under the Vision Shield board. Available libraries allow reading and writing to
FAT16/32 formatted cards.
3.4 Ethernet (ASX00021 only)
Ethernet connector allows connecting to 10/100 Base TX networks using the Ethernet PHY available on the
Portenta board.
3.5 LoRa module (ASX00026 only)
LoRa connectivity is provided by the Murata CMWX1ZZABZ module. This module contains a STM32L0 processor
along with a Semtech SX1276 Radio. The processor is running on Arduino open source firmware based on
Semtech code.

3.6 Power
7 / 17
Arduino Vision Shield Rev 1 - 03/03/2021
The Portenta H7 supplies 3.3V power to the LoRa module (ASX00026 only), microSD slot and dual microphones
via the 3.3V output via the high density connector. An onboard LDO regulator supplies a 2.8V output (300mA)
for the camera module.
4. Board Operation
4.1 Getting Started – IDE
If you want to program your Arduino board while offline you need to install the Arduino Desktop IDE [1] To
connect the board to your computer, you’ll need a USB cable. This also provides power to the board, as
indicated by the LED.
4.2 Getting Started – Arduino Web Editor (Create)
All Arduino and Genuino boards, including this one, work out-of-the-box on the Arduino Web Editor [2], by just
installing a simple plugin.
The Arduino Web Editor is hosted online, therefore it will always be up-to-date with the latest features and
support for all boards. Follow [3] to start coding on the browser and upload your sketches onto your board.
4.3 Getting Started – Arduino IoT Cloud
All Arduino IoT enabled products are supported on Arduino IoT Cloud which allows you to Log, graph and
analyze sensor data, trigger events, and automate your home or business.
4.4 Getting Started – OpenMV
NOTE!
It is highly recommended that you ensure you have the latest bootloader on your Portenta H7 before loading
OpenMV firmware.
Arduino Vision Shield and Portenta H7 are supported under OpenMV. In order to easily use OpenMV download
the latest OpenMV IDE [5] set up Portenta H7 in boot mode by double tapping reset and connect via the
connection button.
Once connected you will receive a message like the following:
Page 8
Click on “OK” and the latest OpenMV firmware will be automatically loaded. To open the “Hello World” example,
8 / 17
Arduino Vision Shield Rev 1 - 03/03/2021
under the File menu select Examples -> Arduino -> Basics and click on helloworld.py.
Click on the green square underneath the connection button to run.
4.5 Online resources
Now that you have gone through the basics of what you can do with the board you can explore the endless
possibilities it provides by checking exciting projects on ProjectHub [6], the Arduino Library Reference [7] and
the online store [8] where you will be able to complement your board with sensors, actuators and more.
4.6 Board Recovery
All Arduino boards have a built-in bootloader which allows flashing the board via USB. In case a sketch locks up
the processor and the board is not reachable anymore via USB it is possible to enter bootloader mode by
double-tapping the reset button right after power up.
