## Description

The Arduino Nano BLE Sense Rev2 packs the nRF52840 processor (32-bit ARM Cortex-M4 at 64 MHz) into the compact Nano form factor, with 1MB flash and 256KB SRAM. It includes Bluetooth 5.0, an impressive array of onboard sensors, and support for TinyML — enabling edge AI and machine learning applications directly on the board using TensorFlow Lite. This version comes with headers pre-soldered for breadboard use. Key Features nRF52840 Processor – 64 MHz ARM Cortex-M4 with 1MB flash and 256KB SRAM Bluetooth 5.0 – BLE with NFC pairing support and ultra-low power consumption modes 9-Axis IMU – BMI270 accelerometer/gyroscope and BMM150 magnetometer Environmental Sensors – LPS22HB barometric pressure, HS3003 temperature and humidity Gesture, Light, Proximity & Colour – APDS9960 multi-function sensor Digital Microphone – MP34DT05 MEMS microphone for audio and voice projects TinyML Ready – Run TensorFlow Lite models for on-device machine learning Pre-Soldered Headers – Ready for breadboard prototyping Specifications Microcontroller: nRF52840 (64 MHz, ARM Cortex-M4) Operating Voltage: 3.3V Input Voltage (limit): 21V DC Current per I/O Pin: 15mA Flash Memory: 1MB SRAM: 256KB Digital I/O Pins: 14 (all PWM capable, all support external interrupts) Analogue Input Pins: 8 (12-bit ADC, 200k samples/s) Interfaces: 1× UART, 1× SPI, 1× I²C USB: Native (nRF52840) Dimensions: 45 × 18mm Part #: ABX00070 Ideal For TinyML and edge AI applications Gesture and voice recognition projects Wearable devices and BLE-connected projects Environmental monitoring with onboard sensors Resources nRF52840 Datasheet BMI270 IMU Datasheet BMM150 Magnetometer Datasheet APDS9960 Datasheet LPS22HB Datasheet HS3003 Datasheet MP34DT05 Microphone Datasheet
