Background
Our retired SR3 racecar uses a Hall current sensor inside the BMS to measure current flowing in and out. However, this type of sensor is overly sensitive to even the Earth's magnetic field, causing inaccurate readings when the car is facing north, south, or at different angles.
For our future car, SR4, we will be using a Shunt current sensor. As part of the electrical subteam, my team has been assigned the task of implementing this sensor in our new vehicle's BMS.
In this project, we are designing a PCB to connect the sensor, amplify its signals using op-amps, and transmit the amplified data to the BMS.

Description
In order to use the ProtoMat and ProtoLaser machines at the Hive, I must first complete the necessary training and obtain approval from one of the Master PIs. As part of this process, I have to print a sample board to finish the training.
I must admit, this project has been both the most challenging and the most exhilarating one I have undertaken. Throughout this project, I have had the opportunity to forge numerous friendships while experiencing a significant personal growth curve.
Given that none of us on the team had prior experience in this particular field, we encountered several obstacles along the way. However, it was these challenges that provided us with invaluable learning experiences.
