Arduino dock defect with power jack
-
Hi,
I blow up my Arduino dock,
I used the power jack with 9v, with arduino uno is there no problem (if you use 5volt its not working).
I can't find a min/max input and of +/- is switched?? so I don't no what I do Wrong.Arduino uno with same setup is working fine.

Is there some-one from Onion that can answer me what to do?

@Anco-van-der-Kolk Hi, the Arduino Dock, while incredibly similar to the Arduino Uno, is not an exact copy. The maximum voltage accepted in the DC Barrel Jack is 5V as stated in the Arduino Dock wiki article: https://wiki.onion.io/Tutorials/Arduino-Dock/Using-the-Arduino-Dock
The next version of the Arduino Dock will either have a warning on the board that says 5V maximum or a voltage regulator that can handle up to 9V.
In the meantime, please file a ticket with our helpdesk and we will do what we can: https://onion.freshdesk.com/

@Lazar-Demin Are there any lists of recommended power adapters for the dock or the PWM expansion?
I cannot seem to find any formal documentation regarding what specifically we should be shopping for when we want to supply power. Having a list we could consult or even an exemplar available for sale in your store would be quite advantageous and might help avoid problems like the one in this (long dead) thread.

as was already mentioned,

select the "power" option to read about powering options. any good 5V adapter, really.

@Samuel-Penning Any 5V DC Power Supply that provides 0.5A or more is good for the Arduino Dock. For the PWM Expansion it depends on your servos. Personally, I've found a 6V, 2A power supply to work well with up to 16 servos!
I'll look into making a list of recommended power supplies.
In the meantime, our documentation site docs.onion.io has good pointers.

For the PWM Expansion: https://docs.onion.io/omega2-docs/pwm-expansion.html#the-dc-barrel-jack-adapterAbout The DC Barrel Jack Adapter
The DC voltage supplied through the barrel jack will be provided on the Vcc (and GND) pins. The PWM voltage will also be stepped up to this voltage.
We’ve safely tested up to 12V, so try not to go beyond that or you risk damaging your Expansion.
I haven't got any PWM Expansion but there's a very good photo in the official Onion Omega2 Documentation.
Onion's PWM Expansion has an NXP PCA9685 16-channel, 12-bit PWM I2C-bus LED controller IC.
According to the NXP Product data sheet Rev. 4 — 16 April 2015Table 13. Limiting values
VDD supply voltage max. +6.0V
VID voltage on an input/output pin max 5.5V
Please let me know what does this "We’ve safely tested ..." statement mean - personally for you and officially for Onion - exactly.
