The Arduino Nano 33 BLE Rev2, a state-of-the-art developer board powered by the nRF52840 from Nordic Semiconductors.
With a 32-bit Arm® Cortex®-M4 CPU running at 64 MHz, this board offers Bluetooth® LE capabilities for seamless data sharing with other Bluetooth® LE enabled devices.
Additionally, it supports MicroPython for increased programming flexibility.
What is the difference between Rev1 and Rev2?
There have been some changes to the sensors, components and PCB design to improve the user experience:
• Replacement of the IMU LSM9DS1 (9-axis) with a combination of two IMUs (BMI270 - 6-axis IMU and BMM150 - 3-axis IMU).
• Replacement of the MPM3610 power supply with MP2322
• V USB solder jumper on the top of the board
• new test point for USB, SWDIO and SWCLK
