Description: Arduino Nano 33 BLE Sense with connectors
The Arduino models in the Nano series are designed to extend the capabilities of small tiles to make their use possible in any project. Arduino Nano 33 BLE Sense is equipped with an energy-saving and efficientnRF52480 microcontroller capable of operating at 64 MHz. There is space for 1 MB of flash memory and 256 KB of RAM onboard. Additionally, the small board was equipped with a number of sensors, which gives a lot of possibilities. Thanks to this unit, the Nano 33 BLE Sense board is the most energy-efficient representative of the Nano family, despite its dimensions. The board supports Bluetooth 5.0 Low Energystandard
Possibilities of Arduino Nano 33 BLE Sense
Arduino Nano 33 BLE Sense is equipped with an aU-block NINA B306module, managingBluetoothcommunicationin 5.0 LE standard. Onboard the Nano there is a 9-axis Inertial Measurement Unit (IMU)LSM9DS1communicating via the I2C bus, which consists of a 3-axis gyroscope, accelerometer and magnetometer. Additionally, the small board is equipped with LPS22HB temperature and pressure sensor, HTS221 humidity sensor, light intensity, colour and gesturesensorADPS-9960. There is also space for the MP34DT05 digital microphone. Additionally, onboard there was also a cryptographic system ATECC608A.
Attention! Arduino Nano 33 BLE Sense can work ONLY with 3.3V by default. Do not supply it directly with 5 V. |
Arduino Nano 33 BLE Sensesupports only 3.3 V by default. There is a jumper in place of the 5V pin in a standard Nano board (between RST and A7 pins) which can be shorted to the USB power supply. To supply 5V power to the devices, solder the jumper and power Nano via USB. If the jumper is soldered and no voltage is obtained from the V in pin. This is a protection to protect the Arduino Nano 33 BLE Sense. The board allows debugging programs, which is done with 6 pads on the bottom of the board underneath the communication system.
