This Is A simple BLDC Driver you can use this Instead of BLDC ESC . i have designed the 2 type of PCB, first is standalone inbuilt PWM or MCU selector which means you can drive your BLDC motor with or without micro-controller selecting the jumper, the second one is just MCU based design, in this board you have to give PWM signal from micro-controller or any other way.
For arduino program you can use blink sketch with 100ms delay , you can copy code from below

// the setup function runs once when you press reset or power the board void setup() {   // initialize digital pin 9 as an output.   pinMode(9, OUTPUT); } // the loop function runs over and over again forever void loop() {   digitalWrite(9, HIGH);   // turn the LED on (HIGH is the voltage level)   delay(100);                       // wait for a second   digitalWrite(9, LOW);    // turn the LED off by making the voltage LOW   delay(100);                       // wait for a second }
