Let's be direct: if you're new to electronics, you've likely looked at two nearly identical boards on Amazon and wondered:
“Wait… is this the real Arduino? Or is this Elegoo just a cheap copy?”
Here's the key point: It's not a copy. It's a clone. And that's perfectly fine.
Most of the Arduino community wants you to use clones like Elegoo. Why? Because Arduino made their designs open-source in 2005 — which is what enabled this entire maker revolution.
However, with numerous kits, confusing specifications, and mixed reviews, how do you choose the right one?
I've researched Reddit threads, Arduino forums, Amazon reviews, and even damaged a few boards (intentionally). Here's the straightforward breakdown — no fluff, no marketing speak.
Quick TL;DR: Arduino vs Elegoo
| Factor | Arduino | Elegoo |
|---|---|---|
| Price | $25–$45+ | $8–$20 |
| Build Quality | Premium, consistent | Very good — sometimes better than official boards |
| Compatibility | 100% | 100% with Arduino IDE |
| USB Chip | ATmega16U2 (real) | ATmega16U2 (on Uno/Mega — NOT CH340!) |
| Starter Kits | Fewer parts, expensive | 200+ components, tutorials, half the price |
| Best For | Pros, commercial use, long-term reliability | Students, hobbyists, beginners, budget builders |
Bottom line: If you're learning? Elegoo wins. If you're building something for commercial use? Go Arduino. And yes — you can use the exact same code, libraries, and shields on both.
The 5 Most Popular Arduino Boards vs Their Elegoo Counterparts
1. Arduino Uno R3 vs Elegoo Uno R3
This is the most common beginner board. And honestly? They’re twins.
| Feature | Arduino Uno R3 | Elegoo Uno R3 |
|---|---|---|
| Microcontroller | ATmega328P-PU | ATmega328P-PU |
| USB-to-Serial Chip | ATmega16U2 | ATmega16U2 |
| Digital I/O Pins | 14 | 14 |
| Analog Inputs | 6 | 6 |
| PWM Pins | 6 | 6 |
| Flash Memory | 32 KB | 32 KB |
| Price | $25–$30 | $8–$12 |
✅ Unlike cheap clones that use the problematic CH340 chip (which requires drivers), Elegoo uses the same ATmega16U2 chip as Arduino. Plug it into your Mac, Windows, or Linux — it appears as “Arduino Uno” without driver issues.
👉 Best for: First-time coders, school projects, learning sensors.
👉 Grab the Elegoo Uno R3 Board (ATmega328P + ATmega16U2)
2. Arduino Mega 2560 vs Elegoo Mega 2560 R3
| Feature | Arduino Mega 2560 | Elegoo Mega 2560 R3 |

4. Arduino Uno R4 WiFi vs Elegoo? (The Curveball)
The Arduino Uno R4 WiFi (2023) features:
- ARM Cortex-M4 processor
- Built-in Wi-Fi + Bluetooth
- 32 KB RAM (vs 2 KB on R3)
- Faster, smarter, more future-proof
Elegoo currently has no R4 equivalent.
✅ Verdict: For learning basics, stick with R3. For Wi-Fi projects, get the genuine R4.

5. Arduino Leonardo vs Elegoo Leonardo
| Feature | Arduino Leonardo | Elegoo Leonardo |
|---|---|---|
| Microcontroller | ATmega32U4 | ATmega32U4 |
| USB Interface | Native USB | Native USB |
| Price | $22–$28 | $9–$13 |
✅ Elegoo Leonardo works 100% — no drivers, no surprises.
👉 Best for: HID projects, custom input devices.

The Honest Verdict: Arduino vs Elegoo
| You Should Buy… | If… |
|---|---|
| Elegoo | You’re a student, on a budget, or just learning. You want more sensors, more value, and zero drama. |
| Arduino (Official) | You’re building something commercial, need guaranteed long-term support, or want to donate to open-source hardware. |
| Both | Buy an Elegoo to learn. Buy one Arduino later to support the community. |
FAQ: Arduino vs Elegoo (Answered by Real Users)
Can I use the Arduino IDE with Elegoo boards?
Yes. Open the Arduino IDE → Tools → Board → Select “Arduino Uno” (even if it’s Elegoo). Done. No extra software.
Are Elegoo boards reliable?
Yes — better than you think. Over 16,000 Amazon reviews for Elegoo Mega boards average 4.7 stars.
Do Elegoo boards work with Arduino shields?
Yes. Pin layout, voltage, and spacing are identical. Stack your motor shield, LCD shield, or Ethernet shield — no problem.
Is Elegoo stealing from Arduino?
Technically, no. Arduino released their schematics as open source. Elegoo is following the rules.
Should I feel guilty buying Elegoo?
No. Arduino’s founder said: “We made this so anyone could build.” Buying Elegoo helps keep the ecosystem alive. But if you can afford it, buy a genuine board once a year and donate.
Final Thought: Buy Elegoo. Then Buy Arduino.
Start with Elegoo → learn the basics, burn a few LEDs, build a robot car. Then, buy an official Arduino → support the open-source movement.
