Design and implementation of a microcontroller development board with Multi Add-on compatibility

Abstract

The goal of this project is to develop an ESP32-based microcontroller that can directly communicate with many add-ons, including Feather, Pmod, and microBUS. This multi-interface microcontroller aims to eliminate the need to buy different microcontrollers for various peripherals or waste time interfacing, thereby lowering expenses and complexity. The study describes the design and implementation procedure, covering schematic design, PCB layout design, and the SMD soldering process. We tested the functionality of the designed board using the mikroBUS temp&Hum 12 click and also with a normal ESP32 and the results were matching and satisfactory.
