Arduino Nano 33 BLE is a 32-bit microcontroller board based on nRF52840 SoC with an ARM Cortex-M4 processor running at 64 MHz. It has 1 MB of Flash and 256 Kbytes of RAM.
Arduino Nano 33 BLE pinout includes 14 digital I/O pins, 8 analog inputs and 12 PWMs. It features UART, TWI (I2C), I2S, SPI, QSPI and 12-bit ADC. The board also has a 9 Axis IMU sensor and provides Bluetooth and Bluetooth LE thanks to the Nina B308 module installed on it.
As shown in the Arduino Nano 33 BLE pinout, the board provides SWD for debugging purpose as well as NFC antenna input to use its internal passive NFC-A tag functionality. 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. This capability, together with Bluetooth connectivity and provided IMU sensor, makes it suitable choice for different robotic, IoT and home automation projects.
