How to confirm SSC-32 burnt out

You can see his death knell here: viewtopic.php?f=8&t=8409&start=45
:frowning:

Disconnect any connected servos and check the voltage on the +5v arduino pins with a multimeter with your power supply connected. If you get 5v, then do the ver test using the lynxmotion application (make sure your baude rates match).

Thanks! Dumb question, but where are the 5v pins? I don’t see them on the ssc32 manual.

If you mean the 5V pins on the actual arduino, it’s not wired up that way, I don’t think it’ll help.

There is voltage to power serial communication.
I think waht zoomkat is trying to do is to confirm you have the 5V for that on the arduino.

It’s not normal that you go thru the 9vdc batt every 10mins.
I suspect you have powered the Logic and power to servo wrong… maybe interchange them ?

I would make a test with a servo and the lynxmotion software direct to the ssc32 and test each output

I see. I figured it was eating through 9V batteries at an alarming rate.
I am running both the arduino and the ssc32 off the same 9V, and the arduino is powering one RGB led as well as the PS2 controller. Perhaps that’s making the difference?

Tested and confirmed, SSC-32 dead to the world. No serial connection, no green light.

Quick plea to the Lynxmotion gods, any SSC-32Us available yet? Looks like they’re almost ready and it’d be a shame to buy another old one right before the new ones come out.

If you look at the below picture, just above and to the right of the main chip, you will see “A B C D” pins with jumpers. On the other side of these jumpers are “- + - +” pins. These are the ground (-) and +5v (+) pins.

Thanks zoomkat, tested them, nothing.

If you connect a known good 9v battery with nothing else connected to the ssc-32, and there is no voltage on the +5v pins, then you probably burned out the low drop out voltage regulator. If you still want to power the ssc-32 from a 9v battery, you can use a standard 7805 voltage regulator with its output connected to the ssc-32 +5v pin.

Would it be possible to use the arduino 5v out for this?

The arduino +5v bus probably supply the logic power needs of the ssc-32. That is how I powered the ssc-32 in the below project. Note that you should try to identify why the regulator failed on the ssc-32 prior to connecting the arduino as a power supply (check the ssc-32 for a short between the 5v bus and ground).

Like he said.
He powered it to 18vdc.

I mean, a new one :slight_smile:

Assuming I get a new SSC-32, how would I use the arduino 5V out to power it? Just straight through to the VL screws?

Plus and minus of the 5vdc on the arduino to VL.
Make sure you have the VL isolated from both VS.

Stupid question: Does arduino have 5V minus, or is that ground?

There is a row of +5v and ground near the usb

If this is the case, that part is $2 at radio shack. Much better than $40 + $10 shipping for a new SSC-32. It’s probably worth a shot.
Clarifications: Only one pin from the voltage regulator goes to the SSC-32? No ground? This plugs into the pins labeled “A” correct?

Your homework assignment. :wink:

Not as of yet. Working on something else first. A few people have the new SSC-32s, but still waiting for a finished version of the firmware. You can power the SSC-32’s logic directly from a BotBoarduino or Bot Board via the 5V / GND (and therefore no need for a separate 9V battery).
