Arduino Nicla Vision integrates STM32H7 MCU with Wi-Fi, BLE and camera support

May 8, 2022 — by Giorgio Mendoza 751 views

The Nicla Vision is built around the STM32H7 (dual core M7/M4). This board comes in a tiny form factor and offers an on-board 2MP camera, Bluetooth 4.2 , Wi-Fi support and a 6-axis IMU. The Nicla Vision can be used as a standalone or in conjunction with Portenta and MKR components.

The microcontrollers used by the Nicla Vision are the Arm Cortex M7 (up to 480MHz) and the Arm Cortex M4 (240MHz). The wireless interface consists of a Murata 1DX Wi-Fi/BT LE module. The 2MP onboard camera supports tinyML which is a platform to run machine learning modules on low power MCUs.
