Arduino Nano not working after burnt ams1117

Other Hardware General Electronics
1

I'm working with Arduino Nano v3 (clone) to build a self-balancing robot using NRF (transmitter-receiver). The problem is: I burned AMS1117 3.3 since I wrongly wired between Arduino board to AMS (short GND to VCC)

But = I can upload my sketch successfully to THAT Arduino but the wheel not spinning at all. The led shows as expected. Then I try to use the Arduino board to other simple sketch and it works fine but NOT for my self-balancing robot.

Then I buy a new one with the same circuit diagram and codes and everything work as expected. Well, really, I'm dead confused.

Here's the result of sketch uploading:

Sketch uses 17392 bytes (56%) of program storage space. Maximum is 30720 bytes.
Global variables use 764 bytes (37%) of dynamic memory, leaving 1284 bytes for local variables. Maximum is 2048 bytes.

avrdude done.  Thank you.

So you have code that works fine on a new Nano but the same code does not fully work on the Nano that you reversed the power on ?

Does that not suggest that the Nano that had the power reversed is damadged in some way ?

NO your nano may not be confused but may as well be regarded as dead. :roll_eyes:

5

Is it possible to fix it, (such as, soldering new AMS1117 5v to the broken board) or something? - instead of buying (always) a new one.

I would advise removing the AMS1117 from the Nano and not trying to replace it, then get a separate ready-assembled regulator module with some degree of heatsinking to power your 3.3 V parts.

I did it but still not working.
I then use AMS1117 5v to supply power for MPU6050 + AMS1117 3.3v (for NRF).
So, 5v and GND in Nano board is not used at all. Then, L298N and Nano board (through VIN) supplied directly to battery (11.1v)

Result: Still Not workiiiing :cry:

NOTE: By the way - I tried to upload Example sketch (servo > Knob) from Arduino IDE and the servo works so good. And, it also works for other simple sketchs.
