Now I am drawing a schematic of the Pico W + Lipo 6S + ML3515 x 4.

Note:DShot ESCs

Most DShot ESCs normally will also operate as normal PWM ESCs.

As noted above, I will use PWM instead of DShot for programming the ESC.

Now I have drafted a schematic.
Troubleshooting Suggestions:
(1) Pico W is 3V3 logic, but XRotor ESC is 5V0 logic. So Pico GPIO 3V3 logic pins might need to shifted up to 5V before connecting to 5V ESC.
(2) Pico GPIO pins are logic signal only, no heavy current flows there, so there is no need to use any flyback diode to prevent back EMF.
(3) Instead, flyback diodes might be needed on the Lipo battery bank side to prevent back EMF damage.
(4) For troubleshooting, a multimeter can be used to measure the total BLDC motor current (at 11.75mV/A).
