STC8H1K28 main controller brushless speed controller, STC official website example. Speed ​​is controlled via potentiometer.
Original post address and firmware are as follows:
BLDC, Three-phase brushless DC motor driver - STC8/STC32 - no hall, 120,000 RPM, video explanation, Liang Gong example - BLDC/144MHz clock source PWM/45-channel PWM+3-channel CCP/7 groups of different cycle PWM/DAC - Guoxin Forum - STC Global 32-bit 8051 enthusiast mutual aid and exchange community - STC Global 32-bit 8051 enthusiast mutual aid and exchange community (stcaimcu.com).
 
The MOSFET used is Quanli AP3910GD 1P+1N 30V 36A. Approximately 1 RMB each on Taobao.
The VCC on the back is intentionally disconnected for soldering a self-resetting fuse during debugging to prevent board burnout.
Actual testing showed that two 18650 batteries, along with a self-wound Dyson motor, easily reached 5A. Suitable for DIY high-performance fans. It has not been destructively tested; it is recommended for use in applications under 3S or less.
