Free CheapUno Debug Kit: Fix Arduino Clone Problems in 30 Minutes

Your CheapUno Clone Is Not Working. Lets Fix It.

I built my first Arduino clone for $5. It took 3 hours to debug.

The problem was simple — loose ground wire. But I did not know where to start.

So I made this free debugging kit to save you those 3 hours.

What Is Inside The Free Kit

1. Power Verification

Is your USB cable providing 5V? Is your voltage regulator outputting the right voltage? Is your battery fresh?

2. Connection Inspection

Are all GND wires connected to a common ground? Are your jumper wires loose? Do you have cold joints?

3. Upload Diagnostics

Correct board selected? Correct port? Is the bootloader alive?

4. Serial Monitor Check

Baud rate match? Garbage characters = wrong baud rate.

5. Common Errors Quick Reference

The most frequent error messages decoded with solutions.

How To Get The Free Kit

All files are free:

• checklist.md - Main debugging flow
• wiring-inspection.md - Visual inspection guide
• common-errors.md - Error quick reference

You can find them in my GitHub repo (link in my profile).
