This PCB was designed by me for my Formula Student Team. The BSPD circuit is a non-programmable circuit which is used to open the shutdown circuit when hard braking occurs. It is placed behind the dashboard. In this circuit we have used EPT 3100 pressure transducer. The circuit uses a quad package dual comparator IC (LM324: A and LM324: B to compare the input signals to threshold voltages set by the potentiometers (ISense and BSE).
The comparator will compare the equivalent voltage with the pre-calibrated voltage. The BSPD circuit checks if the Brake is pressed hard and if there is great
