Currently I am using an arduino promicro with a mpu9250 as a mouse. Can I use the razor in this function without needing to change the code substantially? Is the razor more or less accurate than an mpu9250? Also I would like to avoid soldering if possible.
Hi Feargaill, good question. The Razor 9 DoF M0 IMU board uses the MPU-9250 as the sensor - so it should be able to achieve the same accuracy/precision as your setup and probably even use the same code. The Razor includes a SAMD21 microcontroller with all the necessary connections to the MPU - you should be able to follow the documents on the product page to get started programming the onboard microcontroller.
