The Arduino® Nicla Vision houses the computational power, camera, IMU you need to quickly developed machine vision solutions at the edge together with two wireless technologies. The board can act as a field-ready standalone board, or can be argumented with external peripherals through the I/O available on the chip. Ultra low power consumption and integrated battery management allows for deployment in various capabilities. WebBLE allows for easy OTA update to the firmware as well as remote monitoring.

Warehouse & Automated Inventory Management: The Arduino Nicla Vision is capable of detecting packages as they come near its vicinity and wake up. These provides the benefits of a always-on camera, but with less power consumption. It can take pictures, predict volume/weight and also analyse for possible defects. Additionally, QR codes on the package can be tracked for automated pursuit of the package and relay of information to the cloud.
Real-time process management: The Arduino Nicla Vision is equipped for Automated Optical Inspection (AOI) even in hard to reach and hazardous areas thanks to the small footprint and wireless connectivity options. The fast Time-of-Flight sensor ensures that the image acquisition is performed in a repeatable manner, with minimal modifications to the process. Additionally, the IMU can provide vibration analysis for predictive maintenance.
Wireless Sensor Network Reference Design: The Nicla form factor has been specifically developed at Arduino® as a standard for wireless sensor network which can be adapted by partners to develop custom-designed industrial solutions. Researchers and educators can use this platform to work on an industrially-recognized standard for wireless sensor research and development that can shorten the time from concept to market.

Processor

H7's main processor is the dual core STM32H747 (U1) including a Cortex® M7 running at 480 MHz and a Cortex® M4 running at 240 MHz. The two cores communicate via a Remote Procedure Call mechanism that allows calling functions on the other processor seamlessly.

6-Axis IMU

It is possible to obtain 3D gyroscope and 3D accelerometer data from the LSM6DSOX 6-axis IMU (U3). In addition to providing such data, it is also possible to do machine learning on the IMU for gesture detection, offloading computation load from the main processor.

Wi-Fi/Bluetooth Connectivity

The Murata® LBEE5KL1DX-883 wireless module (U9) simultaneously provides Wi-Fi and Bluetooth connectivity in an ultra small package based on the Cypress CYW4343W. The IEEE802.11 b/g/n Wi-Fi interface can be operated as an access point (AP), station (STA) or as a dual mode simultaneous AP/STA and supports a maximum transfer rate of 65 Mbps. Bluetooth interface supports Bluetooth Classic and BLE. An integrated antenna circuitry switch allows a single external antenna (J6) to be shared between Wi-Fi and Bluetooth.

Crypto Capabilities

The Arduino® Nicla Vision enables IC level edge-to-cloud security capability through the NXP SE050C2 Crypto chip (U8). This provides Common Criteria EAL 6+ security certification up to OS level, as well as RSA/ECC cryptographic algorithm support and credential storage.

Time of Flight Sensor

The VL53L1CBV0FY Time-of-Flight sensor (U4) adds accurate and low power ranging capabilities to the Arduino® Nicla Vision. The invisible near infrared VCSEL laser (including the analog driver) are encapsulated together with receiving optics in an all-in-one small module located below the camera.

Digital Microphones

The MP34DT05 digital MEMS microphone is omnidirectional and operate via a capacitive sensing element with a high (64 dB) signal to noise ratio. The sensing element, capable of detecting acoustic waves, is manufactured using a specialized silicon micromachining process dedicated to producing audio sensors (U6).

Power Tree

Input voltage can be provided to the Nicla Vision through the USB connector (J7), the ESLOV connector (J5), battery connector (J4) or alternatively the headers. The USB connector is prioritized over the ESLOV connector, both of which are prioritized over the battery connector and header. Reverse polarity protection for the USB connector (J7) and the ESLOV connector (J5) are provided by ideal diodes U2 and U7 respectively. Input voltage from the battery does NOT have reverse polarity protection and the user is responsible for respecting the polarity.

A NTC (negative thermal coefficient) sensor provides overtemperature shutoff to the battery. The battery fuel gauge provides indication of the remaining battery capacity

There are three main power lines provided:

+3V1 provides power to the microprocessor (U1), 25 MHz oscillator (U14), 32.768 oscillator (Y1), USB transceiver (U5) and Wi-Fi/Bluetooth module.
+2V8A provides power to the camera (M1) and time-of-flight sensor (U4)
+1V8 provides power to the microprocessor (U1), camera (M1), USB transceiver (U5), Wi-Fi/Bluetooth module (U9), accelerometer (U3), microphone (U6), crypto (U8), FLASH (U13),27 MHz oscillator (U15) as well as the two level translators (U11,U12).
Additionally, a dedicated analog supply rail (VDDA) is provided for the microprocessor (U1). The camera module (M1) also has a dedicated power rail (+1V8CAM).

Board Operation

Getting Started - IDE

If you want to program your Arduino® Nicla Vision while offline you need to install the Arduino® Desktop IDE [1] To connect the Arduino® Vision to your computer, you’ll need a micro USB cable. This also provides power to the board, as indicated by the LED.

Getting Started - Arduino Web Editor

All Arduino® 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.

Getting Started - Arduino Cloud

All Arduino® IoT enabled products are supported on Arduino® Cloud which allows you to log, graph and analyze sensor data, trigger events, and automate your home or business.

Getting Started - WebBLE

The Arduino Nicla Vision provides capability for OTA updates to the STM32 microcontroller using WebBLE.

Getting Started - ESLOV

This board can act as a secondary to a ESLOV controller and have the firmware updated through this method.

Sample Sketches

Sample sketches for the Arduino® Nicla Vision can be found either in the “Examples” menu in the Arduino® IDE or on the Arduino® documentation website [4]

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 [5], the Arduino® Library Reference [6] and the online store [7] where you will be able to complement your board with sensors, actuators and more.

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.

Connector Pinouts

Note 1: All the pins on J1 and J2 (excluding fins) are referenced to the V_{DDIO_EXT} voltage which can be generated internally or supplied externally. Note 2: I2C1 is connected to the level translator U12 which has internal 10k pullups. R9 and R10 pullup resistors are not mounted on the board.
