Goal: The team recently purchases a fixed output power supply that does not have a current or power readout. The goal is to create a PCB that can act as the power supply’s current/power display.

Requirements:

  • The board must be able to determine the current output of the fixed output power supply at 48V and up to 35A or it can be 0-48V

  • The board must be powered by the power supply at 48V

  • The board must include 3-4 seven segment displays (designers choice)

  • They should require no, or a single installment of firmware

Initial Steps:

Find an IC capable of measuring the current output of the power supply
Determine how that IC outputs its readings

Top is ADA, bottom is LT

Determine if a microcontroller is required
Embedded (STM32) - Firmware team needed
Add a socket Arduino
Determine if a seven-segment driver should be used
Off-the-shelf breakout or integrated
Arduino library supported or not/
Determine how the current data output will be translated into a seven-segment display output
Determine how the current reading IC, driver, and microcontroller will be powered
