Receiver ESC 5V boost

Overview

This is a receiver that can be used on fixed-wing model aircraft, integrating a coreless ESC and a 5V boost module.
The main control is STC15W408AS, which communicates with the Si24r1 module through the SPI protocol to achieve 2.4G remote control signal reception. The remote control distance can reach up to 2km.
Use ME2159 to achieve 5V boost, and the maximum current can reach 2A. 5V voltage is directly connected to the servo, which can be used by SG90 and other 5V servos.
Then it is stepped down to 3.3V by AMS1117 to power Si24r1 and the microcontroller.
The motor drive MOS tube uses two AO3402 in parallel, with a maximum current of 6A, and can easily drive a 1020 coreless cup.
Channels 1 and 2 output PWM signals to drive the motor, and channels 3, 4, 5, and 6 PWM signals drive the servos.

Can any expert tell me about the timer?
I am using a 5502 board. In the UARTONCHIP test program on the board, how is 0x56c4,0x0003 in the GPT_Config MyGptConfig {0,0,0,0,0,0x56c4,0x0003,0...} function calculated? Can you tell me the specifi
500kHz MOS tube
Does anyone have a 500kHz MOS tube to recommend? With a withstand voltage of about 50V and a current of about 5A. Thank you!
