Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

i2c communication not working properly when motor is running
Schematics - https://github.com/SRA-VJTI/sra-board-hardware-design/blob/master/renders/sra_dev_board_2022_schematics.pdf
I am using esp32 , tb6612fng(motor driver) and mpu6050 to make a self balancing(two wheeled) bot, these modules are housed on custom made development pcb board. The power source is a 12V 2A(directly given to Motor driver) adapter. the 12V power is stepped down to 5V using LM2596(buck converter)which is powering esp32, then ams1117 is used to regulate 5V to 3.3V(powering MPU6050 and TB6612fng for PWM) . While flashing code to just print the value of roll pitch yaw, I don't get any error , but when I flash the code where motors are running, i2c communication gets interrupted frequently, and hence I am not able to read the MPU6050 values properly, which is required for self balancing.

[PCB Review] I2C communication not working properly when motors are running
I had made a custom general-purpose 2-layer development PCB board that comes in handy for robotics. The aim is to utilize it as a self-balancing two-wheeled robot. Repository Link - SRA-Board_Hardware-Design
