Description
The AP431 and AP431A are 3-terminal adjustable precision
shunt regulators with guaranteed temperature stability over the
applicable extended commercial temperature range. The output
voltage may be set at any level greater than 2.495V (V
REF
) up to
36V merely by selecting two external resistors that act as a
voltage divider network. These devices have a typical output
impedance of 0.2Ω. Active output circuitry provides very sharp
turn-on characteristics, making these devices excellent improved
replacements for Zener diodes in many applications.
The precise (+/-) 1% Reference voltage tolerance of the
AP431/AP431A make it possible in many applications to avoid
the use of a variable resistor, consequently saving cost and
eliminating drift and reliability problems associated with it.

How to solve this ESD problem
Recently, I encountered a project where 8KV static electricity was discharged to the GND of the sub board (copper leakage of the sub board, metal shell of USB), which caused abnormal disconnection of ...

mpu6050 uses the rotation matrix to find whether the acceleration is 1G when stationary regardless of how the quadcopter is placed.
I directly use the quaternion in the dmp library. The formula is calculated based on the atomic solution state->acc.z: accel_z=2*(q1q3-q0q2)*accel[0]+2*(q0q1+q2q3)*accel[1]+(q0q0-q1q1-q2q2+q3q3)accel[...
