Arduino Nano 33 BLE Sense Pinout and Specification

Arduino Nano 33 BLE Sense is a 32-bit microcontroller board based on nRF52840 SoC; with an ARM® Cortex®-M4 processor running at 64 MHz. Arduino Nano 33 BLE Sense pinout includes 14 digital I/O pins, 8 analog inputs and 12 PWMs. It has 1 MB of Flash and 256 Kbytes of RAM. Nano BLE Sense peripherals include UART, TWI (I2C), I2S, SPI, QSPI and 12-bit ADC. The board, as its name implies, provides a great collection of sensors including:

• 9 Axis IMU
• Barometer sensor
• Temperature and Humidity sensor
• Digital microphone
• Gesture, Proximity, Light color and Light intensity sensor

It also supports Bluetooth and Bluetooth LE thanks to the Nina B308 module installed on it.

As shown in the Arduino Nano 33 BLE Sense pinout, it has SWD for debugging purpose as well as NFC antenna input allowing to utilize its internal passive NFC-A tag. The Nina B308 block also provides cryptographic service via its ARM TrustZone Cryptocell 310 subsystem. The board can be powered and programmed via USB Micro B port.

This member of the Arduino Nano family provides much bigger program space than previous generations. Having an array of sensors on board allows you to use it for a whole spectrum of projects such as weather station, wearable devices, generating and synthesizing sounds, etc.
