Title: Axon II Soldering
Post by: adscott1982 on June 01, 2010, 04:14:01 PM

Hi Guys,

I just received my Axon II from the USA. Super excited to get started but did a visual inspection and found a couple of the pins were soldered together. I'm not sure if it's intentional or not.

The pins are Bat + and G5 +.

Please find attached images:

Shouldn't be intentional, but you won't have a problem for sure... At least if it's on the same power line... which most possibly is... ;-)

Oh cool, that makes sense!

Thanks for the info.  :)

Nothing... but take a quick glance at the specs to see if what I told you for the power bus is correct...

If both are Vbat it's ok
If both are 5V it's ok
If both are 3.3V it's still ok...

If they intertwine it's NOT ok...

According to the datasheet:

http://www.societyofrobots.com/axon2/axon2_datasheet.shtml (http://www.societyofrobots.com/axon2/axon2_datasheet.shtml)

They are all Battery, so it should be OK, right?

Yep, that joint makes that power bus battery voltage.

Its a power jumper. If you leave it, you only need one battery. If you remove it, you can power the mcu with a small battery and the servos on the power bus with a different larger battery.

See datasheet for details:
