Hey all,
well, it happened, i completely fried my beloved Arduino Micro by shorting Vin to GND =(
Thats the reward for being too lazy to check the circuit before "flipping the switch".
Now, before using another Arduino, i'd like to collect some DON'Ts (and maybe DOs) to prevent something like this again. Yeah, i know, doing electronics sometimes involve going up in smoke and smell bad, but maybe it is a good practice to accustom some safety-procedures.
I already searched for a
collection of ways to stress/damage/destroy your Arduino:
- Shorting I/O Pins to Ground
- Shorting I/O Pins to Each Other
- Apply Overvoltage to I/O Pins
- Exceed individual I/O Pin Current
- Apply External Vin Power Backwards
- Apply >5V to the 5V Connector Pin
- Apply >3.3V to the 3.3V Connector Pin
- Short Vin to GND
- Apply 5V External Power with Vin Load
- Apply >13V to the Reset Pin
- Exceed Total Microcontroller Current
- Changing Connections While Powered Up
- Not Using FlyBack Diodes With Inductive Components Like motors, solenoids & relays
- Connecting a 5 volt supply to the 5V pin while connected to USB
- any more...?
of course i got most of these from this article: 10 Ways to Destroy an Arduino — Rugged CircuitsRugged Industrial Arduino Microcontrollers
Is there anything else for this list (except the obvious) or any good procedure you do when designing/buildind circuits?
