Redesign the Data Conversion board from the previous year's ROV into a Sensor Stem board that works with the stack being designed this year and update documentation for the board

The Data Conversion board from last year initially helped the Power Distribution Bricks relay brick status and error messages to the Raspberry Pi by converting PMBus to CAN using an STM chip

• Learned how the hardware for CAN works within a larger system

  • Selected CAN transceivers, looked at datasheet to determine supporting hardware, selected specific resistor to configure slew rate, coordinated with other boards to determine location of terminating resistors, etc.  

• We initially continued the development of this board under this assumption

• The slideshow is a mid-semester update I provided on the status on the board

• When looking into integrating the boards, the team realized the new Power Distribution Bricks we ordered did not have this functionality, so the team decided to convert the board into a sensor stem board

The Sensor Stem board takes analog signals from external sensors and uses a STM chip to process it

• Talks with the rest of the electrical stack using CAN

During the season, I also helped with soldering and testing other boards

• This involved making connectors, testing electrical connections, and using oscilloscopes to make sure the output of the boards were stable
