This project is a compact and reliable USB-to-Serial converter based on the CP2104 chip. It is designed for seamless communication between your computer and microcontroller-based systems.
- ✅ Small and compact form factor
- 🔌 USB Type-C connector for modern and reversible USB connection
- 📌 Standard 2.54mm pin headers, fully breadboard-friendly
- 🔁 Selectable VCC output: toggle between 3.3V and 5V using an onboard switch
- 🔧 All serial pins (TX, RX, GND, VCC) are easily accessible
- 💡 Ideal for prototyping, debugging, and development with Arduino, ESP32, STM32, and more
