Configuring Santroll controller

I seek some help to modify the rpm/speed limit on my ebike with 36v 250w motor.
The ebike has a Santroll controller with Rated Voltage 36V and Rated Current 5A.
Maximum current is 10A.
I did a little research on Santroll controllers and found these topics each talking about a blue wire. But couldn't make much sense out of them.

Any help would be appreciated.

Hello,
I have the same type of controller on a bike Xiaomi HIMO C20.

1) What is the reference of your bike?

2) Did you get technical information ?
The name of the application allows to modify the configuration, source code, the name of the communication protocol, pin identification on the pcb, identification of color cable ?

3) Do you know what is the reference of the controller?
I am looking to buy a second one on the Internet.

Best regards

2. No. For the color coding I guess its same for most of the Chinese controllers.
3. You can buy any other controller if you know the power output of your motor and the batteries. Also do check if your motor has hall sensors. There are separate controllers for - with sensor and sensorless bdlc motors.

Thank you, we have not found a compatible controller have our display and engine for now.

Can you give me the reference of your electric bike? This will give us new way to explore.

Also, have found information to configure this controller?

hello, How do I remove the speed limit on this controller? (the bike xiaomi himo c20) Thank you!
