Gyroscopic Wearable Device Insights

flux

Based on Flux knowledge-base guidance (“selecting MCU for simple project”), it’s best to choose an MCU with just enough I/O and processing headroom to run a 9-axis IMU and ELRS stack without excess peripherals that waste power.
Below are three recommended MCUs and three high-accuracy IMUs. All links use Flux library search URLs so you can inspect footprints, availability, and datasheets instantly.
