BNO055 calibration is four separate 0–3 states. Save offsets only after system, gyroscope, accelerometer and magnetometer all report 3 in the intended operating mode.
BNO055 Calibration Status: Save Offsets Only After All Four Values Reach 3 Read More
An H-bridge can leave a motor electrically open or short its terminals during a stop. That choice changes current decay, braking torque and how repeatable a robot’s stop feels.

A VL53L1X can return unstable or failed continuous readings when its intermeasurement period is shorter than its timing budget. Configure the measurement window first, then leave scheduling margin.
VL53L1X Timing Budget: Keep the Intermeasurement Period Longer Read More
A PCA9685 stores pulse edges as 12-bit counts, not microseconds. Convert the servo pulse width using the actual PWM frequency, then calibrate the oscillator before trimming endpoints.
PCA9685 Servo Timing: Convert Microseconds to 12-Bit Counts Without Guessing Read More
A four-wire bipolar stepper has two isolated windings. Use resistance or continuity—not wire colors—to identify the two pairs before connecting A1/A2 and B1/B2.
