The Arduino Nano 33 BLE Rev2, an upgraded model of the Arduino Nano 33 BLE board that was launched in 2019, is the most recent growth within the Web of Issues (IoT) {hardware} discipline. The numerous updates of this new board embody the mixing of two Inertial Measurement Unit (IMU) sensors, particularly the BMI270 6-axis accelerometer and gyroscope, and the BMM150 3-axis magnetometer, as a substitute of utilizing just one IMU sensor as within the earlier model.
These updates are based mostly on consumer suggestions and have been integrated to boost the performance and efficiency of the board. Along with the twin IMU sensors, the board additionally options new pads and check factors for Common Serial Bus (USB), Serial Wire Debug Enter/Output (SWDIO), and Serial Wire Clock (SWCLK). Moreover, a brand new Voltage USB (VUSB) soldering jumper has been added, and the ability circuitry has been revamped.
Unpacking the Arduino Nano 33 BLE Rev2 Specs
The Arduino Nano 33 BLE Rev2 continues to be powered by the nRF52840 Bluetooth Low Power (LE) module, which is a part of the u-Blox NINA B306. The board retains Arduino Nano compatibility with two rows of 15-pin headers. Nonetheless, the 9-axis IMU sensor has been changed with the BMI270 and BMM150 chips.
The specs of the brand new board embody an Arm Cortex-M4F microcontroller working at 64MHz. The board additionally contains 1MB Flash reminiscence and 256KB RAM for storage. The BLE 5.0 LE facilitates a hyperlink charge of as much as 2 Mbps, with long-range help, and has a +8 dBm TX energy and -95 dBm sensitivity. The ability consumption of the board is 4.8 mA in TX (0 dBm) and 4.6 mA in RX (1 Mbps).
The board additionally helps enlargement with 2x 15-pin enlargement headers that embody Normal-Objective Enter/Output (GPIO), Serial Peripheral Interface (SPI), Inter-Built-in Circuit (I2C), Common Synchronous/Asynchronous Receiver/Transmitter (USART), Pulse Width Modulation (PWM), Analog-to-Digital Converter (ADC), Digital-to-Analog Converter (DAC), reset, and energy indicators. Nonetheless, it’s important to notice that the board solely helps 3.3V I/Os and isn’t 5V tolerant.
Improved Sensor Capabilities and Debugging
The Arduino Nano 33 BLE Rev2 is supplied with a BMI270 6-axis accelerometer and gyroscope, and a BMM150 3-axis magnetometer with a 0.3μT decision. This enhanced sensor functionality permits for extra correct and exact measurements. Debugging is facilitated through the micro USB port and the 6-pin solder pads. New pads and check factors for USB, SWDIO, and SWCLK have been added to streamline the debugging course of.
Energy Provide and Dimensions
The ability provide for the board will be supplied by means of a 5V micro USB port or VUSB pin on the header. The board additionally helps a voltage enter starting from 5V to 18V through the Vin pin. The MP2322 DC-DC step-down converter regulates the enter voltage as much as 21V with a minimal of 65% effectivity at minimal load and greater than 85% effectivity at 12V. The size of the board are 45 x 18 mm, which is suitable with Arduino Nano, and it weighs simply 5 grams.
Getting Began with Arduino Nano 33 BLE Rev2
The Arduino Nano 33 BLE Rev2 is suitable with the primary technology of the board and will be programmed with Arduino or MicroPython. Customers are suggested to replace the board help and libraries to the most recent model for optimum efficiency. The board will be bought for $24.17 / 22.80 Euros with out headers or $26.92 / 25.40 Euros with out headers on the Arduino retailer.
For these focused on additional technical particulars, getting began directions, and tutorials, these sources will be discovered on the official documentation web site.
It’s noteworthy that the Arduino Nano 33 BLE Sense Rev2 was launched final yr with the identical BMI270 and BMM150 chips, plus further sensors, together with the MP34DT06JTR microphone, APDS9960 gesture, gentle, proximity sensor, LPS22HB barometric strain sensor, and Renesas HS3003 temperature & humidity sensor.
The event of the Arduino Nano 33 BLE Rev2 is a testomony to the continual developments in IoT know-how. This board, with its improved sensor capabilities and up to date options, is predicted to play a major function in future IoT tasks and purposes.
