Arduino® Nano 33 IoT 1 The Board As all Nano form factor boards, Nano 33 IoT and Nano 33 IoT with headers does not have a battery charger but can be powered through USB or headers. NOTE: Arduino Nano 33 IoT and Nano 33 IoT with headers only supports 3.3V I/Os and is NOT 5V tolerant so please make sure you are not directly connecting 5V signals to this board or it will be damaged.

Description SJ1 Open solder bridge (VUSB) SJ4 Closed solder bridge (+3V3) TP Test points xx Lorem Ipsum 3.2 Processor The Main Processor is a Cortex M0+ running at up to 48MHz. Most of its pins are connected to the external headers, however some are reserved for internal communication with the wireless module and the on-board internal I2C peripherals (IMU and Crypto).
Arduino® Nano 33 IoT 3.4 Crypto The crypto chip in Arduino IoT boards is what makes the difference with other less secure boards as it provides a secure way to store secrets (such as certificates) and accelerates secure protocols while never exposing secrets in plain text. Source code for the Arduino Library that supports the Crypto is available [10] 3.
Arduino® Nano 33 IoT Power tree 4 Board Operation 4.1 Getting Started - IDE If you want to program your board while offline you need to install the Arduino Desktop IDE [1] To connect the Arduino 33 IoT to your computer, you’ll need a Micro-B USB cable. This also provides power to the board, as indicated by the LED. 4.2 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.
Arduino® Nano 33 IoT 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 doubletapping the reset button right after power up.
Arduino® Nano 33 IoT 5.1 USB Pin Function Type Description 1 VUSB Power Power Supply Input. If board is powered via VUSB from header this is an Output (1) 2 D- Differential USB differential data - 3 D+ Differential USB differential data + 4 ID Analog Selects Host/Device functionality 5 GND Power Power Ground 1. The board can support USB host mode only if powered via the VUSB pin and if the jumper close to the VUSB pin is shorted. 5.
