How to connect T200 thruster and raspberry pi 4

I tried lots of code from the Internet including yours (Rasbperry pi 3 and t100 thrusters - #3 by karkotis)but the raspberry still cannot generate the normal pwm and activate the thruster to spin (following is how we connect. We don’t know whether it’s right) Thanks.


Is that an IMU on the protoboard? Where is the ESC?
