carbide motion board details?

Post by rtlflatt » Thu Apr 16, 2015 10:58 am

anybody currently in possession of an so3 able to give any more details on board? checked wiki n couldnt see anything new

1) does come with grbl .9i or a different version?
.9i as far as I can tell

2) is it still ATmega328 used on board?
Yes arduino uno built in

3) what pins are broken out for us?
I don't we A3, A4, or D13

4) if there are pins not broken out to headers is there at least some where we can access them if needed?
See above

5) what drivers are they and how much current they provide?


had couple other questions too but its 4am and idk why im up right now so ill have to try and remember what they are later

Has the board schematic or pin out details been released yet?

What amperage will the 5VDC provide?

What 12vDc amperage will the fan connector provide?

On the accessory connectors for axis limits, stop, probe, etc, is one side consistently tied to ground?

dont think so. when i talked to edward at maker faire he said that they still plan on releasing that at some point as well as mentioned possibility of limit switch kit but no timeline.

as for powering superpid (what u want to use the 5v for if not that?)...

found this page here. not really an answer but personally i will be using a regulated power brick and not have to worry about it.

which states:

-The 5V output pin is good for ~400 mA on USB, ~900 mA when using an external power adapter
-The 900 mA is for an adapter that provides ~7V. As the adapter voltage increases, the amount of heat the regulator has to deal with also increases, so the maximum current will drop as the voltage increases. This is called thermal limiting

and just below that:

Note: This does not apply to the Arduino Due, and there are likely some differences for the Arduino Mega. It is likely generally true for any Arduino based off the ATmega328 microcontroller.

I'm looking for a power source to run two things: LED lighting on the dust shoe and I need 5-24VDC for Hall effect sensors. I think it would be easiest to pull the 12VDC from the fan connector and run to a breakout board for the remainder of the wiring.

how much current need for sensors? not much im sure. and fan isnt 24v?

The fan is 12VDC, I picked up some LED strip lights which are 12V.

The hall sensors will probably draw 40 mA each max by the time I add an indicator x 5 so 200mA max, realistically only three at a time would pull max current on the homing operation.

I see a header for ISP. Also one labelled "Serial Programmer". I am looking for a way to bypass the USB port and connect in serial for use with a bluetooth board. Just need access to tx, rx, rst and Vcc. Any ideas?
