The task was to :Design and develop a multi-purpose IoT development board with onboard sensors that can
be used for various IoT projects and real-world applications.

Core Project Requirements
task is to design the PCB hardware only (no firmware/software required for this stage).
The board must be:
● Compact and modular
● Easy to power (via battery or USB)
● Equipped with the following components:
○ ESP32-WROOM-32E MCU
○ BME280 (Temperature, Humidity, Pressure sensor)
○ ADXL345 (Accelerometer sensor)

⚙️ Additional Components
● Power Supply Options:
○ USB input (via Micro USB or USB-C)
○ LiPo battery (via JST connector)
○ LDO Regulator (e.g., AMS1117 or MCP1700) for 3.3V output.
This happened to be one of my first printed circuit boards designs
