Description
This is the cheapest and most budget-friendly Arduino Uno option for students, beginners, and hobbyists. It includes the same ATmega328P microcontroller, full Arduino compatibility, and identical performance — just at a much lower price.
The board uses an ATmega328P SMD version and the popular CH340 USB-serial chip instead of the more expensive components found on the official Uno. Functionally, everything else is the same: pin layout, memory, performance, and compatibility.
Perfect for Arduino learners, robotics, project prototyping, and STEM education.
এটি বাজারে পাওয়া সবচেয়ে সস্তা এবং বাজেট-ফ্রেন্ডলি Arduino Uno। শিক্ষার্থী, বিগিনার এবং DIY মেকারদের জন্য ideal।
একই ATmega328P মাইক্রোকন্ট্রোলার, একই পারফরম্যান্স, একই কম্প্যাটিবিলিটি — শুধু কম দামে।
এখানে ব্যবহৃত হয়েছে ATmega328P SMD চিপ এবং CH340 USB-টু-সিরিয়াল চিপ, যা স্ট্যান্ডার্ড Arduino Uno এর তুলনায় কম খরচে পাওয়া যায়।
তবে পারফরম্যান্স এবং ফিচার ১০০% একই।
Difference Between This Board & Standard Arduino Uno
| Feature | Budget UNO | Official/Standard UNO |
|---|---|---|
| Main MCU | ATmega328P SMD | ATmega328P DIP (removable) |
| USB Interface | CH340 | ATmega16U2 |
| Price | Much cheaper | Expensive |
| Performance | Same | Same |
| Pin Layout | Same | Same |
| Code Compatibility | Same | Same |
✔️ All Arduino libraries, sensors, and shields work the same way.
