1. The board As all Nano form factor boards, Nano 33 BLE Sense does not have a battery charger but can be powered through USB or headers. NOTE: Arduino Nano 33 BLE Sense 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. Also, as opposed to Arduino Nano boards that support 5V operation, the 5V pin does NOT supply voltage but is rather connected, through a jumper, to the USB power input.

Bottom: Ref. Description Ref. Description SJ1 VUSB Jumper SJ2 D7 Jumper SJ3 3v3 Jumper SJ4 D8 Jumper 3.2 Processor The Main Processor is a Cortex M4F running at up to 64MHz. 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).
Source code for the Arduino Library that supports the IMU is available [9] 3.5 Barometer and temperature sensor The embedded Barometer and temperature sensor allow measuring ambient pressure. The temperature sensor integrated with the barometer can be used to compensate the pressure measurement. Source code for the Arduino Library that supports the Barometer is available [10] 3.6 Relative humidity and temperature sensor Relative humidity sensor measures ambient relative humidity.
ambient light and sense color which enables devices to calculate color temperature and control display backlight. 3.8 Digital Microphone The MP34DT05 is an ultra-compact, low-power, omnidirectional, digital MEMS microphone built with a capacitive sensing element and an IC interface.
3.9 Power tree The board can be powered via USB connector, VIN or VUSB pins on headers. NOTE: Since VUSB feeds VIN via a Schottky diode and a DC-DC regulator specified minimum input voltage is 4.5V the minimum supply voltage from USB has to be increased to a voltage in the range between 4.8V to 4.96V depending on the current being drawn.
4. Board Operation 4.1 Getting started - IDE If you want to program your Arduino Nano 33 BLE while offline you need to install the Arduino Desktop IDE [1] To connect the Arduino Nano 33 BLE 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.
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.
4. Connector Pinouts 4.1 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 4.2 Headers The board exposes two 15 pin connectors which can either be assembled with pin headers or soldered through castellated vias.
