STEVAL-MKI127V1
Ultra stable 3-axis gyro based on the L3GD20-
Active
The STEVAL-MKI127V1 demonstration board represents an ultra stable 3-axis gyroscope application based on MEMS technology, offering high quality and performance at a low price. Utilizing ST’s L3GD20 low-power 3-axis angular rate sensor and ARM Cortex-M3 processor, it offers users an unprecedented level of fine tuning/programming to meet the needs of professionals and hobbyists alike. It is ideal for any number of UAV, conventional aircraft, platform stabilization (such as camera mounts), or general robotics projects, as well as providing optimal performance for competitive RC airplane and recreational flying.
The STEVAL-MKI127V1 was designed by Bluelight Technologies Co. Ltd.
