ESP32 & Digispark USB Custom PCB Projects – KiCad Practice Designs

June 1, 2025 – Present

I recently built two microcontroller boards in KiCad as practice projects:
• 🔌 ESP32 Development Board
Designed ESP32 board features USB-C for power and programming, onboard buttons, SMD passives, and pin headers for easy expansion. Great for IoT prototyping, wireless communication, and embedded systems projects.

• 🔋 Digispark USB Board
Rebuilt a compact board based on the ATtiny85 microcontroller that connects directly via USB. It can function as a programmable input device, simple automation controller, or a DIY USB gadget.

These projects helped me practice schematic design, component placement, routing, and power decoupling.

CPR Assistance Device Competition

Nov. 16, 2024 – Nov. 16, 2024

• Designed and prototyped C-based firmware for an Arduino-powered infant CPR training device, enabling real-time monitoring of chest compression depth and rhythm feedback.
• Led a team of 5 multidisciplinary engineers and coordinated project timelines, delegated tasks, and ensured on-time delivery of the device, earning 2nd place out of 5 registered teams.

Design of a Simple Central Processing Unit (CPU)

Nov. 1, 2024 – Dec. 17, 2024

The goal of this project was to develop a simplified CPU in Quartus II (VHDL) environment and further implement the outputs using FPGA boards. There are three parts in this project: Initial Design, Modified ALU core 1, and Modified ALU core 2. Each part has its own ALU and block diagram, which also includes other components such as seven-segments, some decoders, registers, and a finite state machine (FSM) to implement the corresponding logic.
This is a small-group project and was built by me and my friend Aharen Kuganesan.
