Brushless ESC PN double layer v2

[Drones] The road to learning brushless ESCs.
Learn from this article: Moba author [I Love Loli Love Loli] 2020 new version of brushless ESC DIY tutorial [https://www.moz8.com/forum.php ?mod=viewthread&tid=182113&fromuid=111906] Without further ado, here’s a video: [[Demo video](https://b23.tv/KN0fKiL)
**1. Hardware selection** 1. MOS tube selection: AON6407 + AON63542. MCU selection: STC15W408AS-35I-SOP163. Voltage regulator tube selection: AS78L05RTR-E14. Transistor selection: SS80505. Power supply interface selection: XT30PW-M6. Firmware programming interface: GH125-S04DCA-007. Resistors, capacitors and other components The components are according to the table*** Some components are different from the author of the original poster. More suitable components are selected through personal experience***  
**2. Circuit board design**
This project is designed using [Jialichuang EDA software]. Jialichuang's EDA software is very suitable for beginners and easy to get started. There are also official free tutorials, which is worth recommending. The design diagram is as follows: 8. Schematic  
** IV. Software and hardware testing ** 1. In order to facilitate the replacement of the motor, a 3P banana head was welded at the motor connection. Since I did not buy the XT30 connector, the power cord was welded directly to C10 There is a polarized capacitor bit (the capacitor is not soldered). **5.
