Custom PCB Design, Layout, & Assembly: T^2 - an Ambient and Object Temperature Sensor

For my final project for EE156: Board Level Design, I built a custom PCB using an ATSAMD51J19A-AUT microprocessor, ESP32 Wifi-Module, infrared temperature sensor, BME688 temperature, pressure and humidity sensor, USB-C port (later surgically changed to micro-USB), microSD-card reader, and push buttons.
