What is the difference between Rev1 and Rev2? There has been some changes in the sensor between both revisions: Replacement of IMU from LSM9DS1 (9 axis) for a combination of two IMUs (BMI270 - 6 axis IMU and BMM150 - 3 axis IMU). Replacement of temperature and humidity sensor from HTS221 for HS3003. Replacement of microphone from MP34DT05 to MP34DT06JTR. Additionally some components and the changes have been done in order to improve the experience of the users: Replacement of power supply MPM3610 for MP2322. Addition of VUSB soldering jumper on the top side of the board. New test point for USB, SWDIO and SWCLK. 2. Do I need to change my sketch used in the previous revision? For sketches done using the libraries like LSM9DS1 for the IMU or HTS221 for the temperature and humidity sensor, for the new revision this libraries must be changed to ArduinoBMI270BMM150 for the new combined IMU and ArduinoHS300x for the new temperature and humidity sensor.
