Arduino Nano 33 BLE Rev2 board features BMI270 six-axis IMU and BMM150 magnetometer

Arduino Nano 33 BLE Rev2

Arduino Nano 33 BLE Rev2 is an update to the Arduino Nano 33 BLE board launched in 2019 that features two IMU sensors instead of one with the BMI270 6-axis accelerometer and gyroscope and the BMM150 3-axis magnetometer and also comes with a few changes made after feedback from users. The new board is still powered by an nRF52840 Bluetooth LE module (u-Blox NINA B306) and remains Arduino Nano compatibility with two rows of 15-pin headers, but replaces the 9-axis IMU with the BMI270 and BMM150 chips, adds new pads and test points for USB, SWDIO, and SWCLK, a new VUSB soldering jumper, and brings changes to the power circuitry. Arduino Nano 33 BLE Rev2 specifications: Wireless Module – U-blox NINA B306 module SoC – Nordic Semi nRF52840 MCU Core – Arm Cortex-M4F microcontroller @ 64MHz Memory and storage – 1MB Flash, 256KB RAM Bluetooth 5.0 LE Up to 2 […]

EVN Alpha is a LEGO-compatible robotics controller built around Raspberry Pi RP2040 MCU (Crowdfunding)

EVN ALPHA Raspberry Pi RP2040 Robot

The EVN Alpha is a robotics project from a team based in Singapore and is aimed at roboticists seeking an advanced building platform beyond what LEGO Robotics kits offer. This robotics controller can be considered a spiritual successor to the LEGO MINDSTORMS EV3 intelligent brick. It runs on the Raspberry Pi RP2040 microcontroller with two Cortex M0+ cores running at a maximum clock speed of 133 MHz and 264KB of embedded SRAM and builds upon the rich software support available for the microcontroller. It features 64 LEGO Technic-compatible holes on five sides for easy installation into your projects and has 26 ports for I2C, UART, servos, EV3, and NXT motors. It is smaller volumetrically than the LEGO bricks and can be powered from two generic 18650 Lithium-ion cells rather than a proprietary solution (unlike the LEGO SPIKE Prime). The EVN Alpha was created as a “basecamp for students looking to […]
