HOVERBOARD MOTHERBOARD HACK - how to controll the motors PART 2 - Hover Board Hack

The second part of hacking a hoverboard motherboard, in this video i show you which wires to connect to what to make the motors move how you want,

I cant put the code here so i will put it in a comment for you

make sure you also get the Adafruit_MCP4725 and WIRE libraries or it wont work, feel free to ask questions in the comments

[A-tech]

The arduino code from the video:


#include <Wire.h>
#include <SPI.h>
#include <Adafruit_MCP4725.h>

int pot1 = A0;
int pot2 = A1;

int set1 = 0;
int set2 = 0;

uint32_t dac_value = 0;
uint32_t dac2_value = 0;

Adafruit_MCP4725 dac;
Adafruit_MCP4725 dac2;



void setup()
{
Wire.begin(1); // Activate I2C link
Serial.begin(115200);
dac.begin(0x60);
dac2.begin(0x61);

}


void loop()
{
set1 = map(pot1, 0, 1024, 0, 255); //steer 0 - 255
set2 = map(pot2, 0, 1024, 0, 255); //throttle 0 - 255

if(set1 < 131 && set1 > 120){ //no steer
dac_value = 2045;
}else{
dac_value = map(set1, 255, 0, 0, 4095); //steer amount 0 - 4095
dac.setVoltage(dac_value, false);
}

if(set2 < 120){
dac2_value = map(set2, 120, 0, 1600, 4095); //forwards
dac2.setVoltage(dac2_value, false);
}
if(set2 > 130){
dac2_value = map(set2, 131, 255, 1600, 1059); //reverse
dac2.setVoltage(dac2_value, false);
}
if(set2 > 119 && set2 < 131){ //stop
dac2_value = 1600; // 0-4095
dac2.setVoltage(dac2_value, false);
}

delay(0);


}

This is awesome!! Just followed your guide and I now have it running on an old amp volume knob and two makita batteries. I am hoping to use this to drive a small milling machine I have. Can't wait to test it in a woods somewhere. Thanks Bud.

Thanks for the tutorial. I have a question, it goes so much slower in reverse and the torque drops significantly. Is there a way to solve this, so that it has the same power forvard and reverse.

Hi i got a question i saw on auctions there exist 2 diffrent pcb boards green and dark blue of that board with one is better or newest?

[rainbowpoop]

Hi could you please make a more detailed video on how to connect the Arduino to the mother board and how to use ps3 controller to control the motors. Also can this work with Arduino uno?

[smartlui]

Good video! Thanks. What about a video controlling the motors with a Bluetooth connection via Arduino and app inventor? 🤩

[pxl]

nice . did you manage to use this with ebike throttle ? and use regen braking ?

[talon]

Could i replace the potentiometer with a thumb throttle? I just want to make a drift trike but im getting confused.

And, do i need the steering potentiometer? I want both wheels to always to rotate the opposite direction same speed to be like my rear axle.

[WorkWithoutHuman]

Can You help me something, looks like You've studied the board. Where is located the switch or the jumper or the wire for "locking" the 2 wheels, to turn synchronized? To control both from one control?
Thanks!

[TheLordbruh]

congratulations! my board has the at AT32F403RCT6 component. do you have the procedure to apply on this type of board?

[samirsuleymanov]

Thank you for great video! Can it be used for simulator steering wheel force feedback?

[johnsnykers]

Hey..Nice job.i had a question..if i want to connect a ethrottle on a hoverboard.i only want it to go forward.the throttle has 3wires.thank you john

[willworkforfood]

Hello again, great vid used it for a few projects. Is there a reverse function?.

[digitalvideoshow]

amigo, onde consigo esse firmeware, vc tem um link ?

[LifewithLewy]

Please bear with me because I am a beginner, but I have a few questions. I see you are using two break out boards, one for each potentiometer. If I’m wiring two motors to one joystick do I need 4 breakout boards or just 2? It seems to me like I would need 4

[cleeeen]

Say if I want one of the pentiometers to be a foot pedal, it has the three wires but the only thing is it says 12 to 48v, will I be able to use it

PLEASE RESPOND!!

Can 50k potentiometer work for this process??

[petarilic]

Nice work, I've done this to my motherboard, but i conected only one motor, and tested it. It was fine until i sensed some heat coming from the wires of the motor phases, and also motor sounded like something was cracking. Can you asume what might be wrong?

[giorgiolelmi]

Can you help me? What pins do I have to solder on the Digital-to-analog converter to change its address of it? I found 8 pins on it but I don't know which one is the right one. I'd be really happy if you would take a moment to help me :D

can i use throttle insted of potentiometer Please answer
