LPC-826 Handheld case pin?

[furrylaser]

So I was going to build a handheld laser using this host in a pocketmini host. Im an not really sure how to wire it up. This would be my first handheld. I am using a flexdrive and i believe that you just solder the + to the + of the driver and vice versa.

so you do nothing with the un-used pin?

So from what i have read the case pin on the lpcs is already negative?

^^^yes. just hook it up like the diagram

the case pin is your negative hence you have a case negative diode!
