Arduino® Nicla Vision

14 / 19 Arduino® Nicla Vision Modiﬁed: 08/03/2022

4.4 Getting Started - WebBLE

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

4.5 Getting Started - ESLOV

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

4.6 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]

4.7 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.

4.8 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.

5 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.
