Four axis NT32

The question requires
the national technology microcontroller N32G430C8L7 quadcopter;
the question analysis
realizes the self-stabilization, remote control, and height determination of the quadcopter (I didn’t say it);
 
the schematic design shows that
the flight control power supply
first boosts and then reduces the voltage because the rotation of the motor will cause the battery to When the voltage is pulled down, it is estimated that it can be pulled down to about 3.6V in the test. Directly using LDO will cause 3.3V to be unstable; of course, you can also directly use 2S batteries. By the way, it is recommended to short-circuit this switch directly, and then use an external switch with a larger overcurrent. This small switch will be burned.
The remote charging management
TP4056 charges the 1S lithium battery through the 5V power supply from the TYPEC interface. At the same time, it also includes temperature protection and overcharge/over-discharge protection circuits to ensure the safety of battery charging. The PROG pin of TP4056 is connected to an external 1.2K resistor to set the charging current to 1A (approximately more than 100 mA measured with a multimeter, but Definitely not allowed).
Software description:
The software structure is basically Xiao Ma's software design. Currently, the function is only for flying. When it comes to setting altitude, the barometer data is hard to explain. I hope the experts can write it down and teach me. Maybe I will change the plan later.
 
The physical display explains
the precautions.
Although it is a hollow cup, your hands will still turn red when you turn it. Pay attention to safety.
