USA TTL driver board supplier
« on: June 18, 2018, 05:49:19 PM »
Is there anywhere I can order a TTL driver board and not have to wait a month for delivery?  Everything must come from China it seems.

That's very vague. What do you consider a TTL driver board?

That looks like a laser driver or constant current power supply.

You can get them from banggood, ebay or aliexpress. What they don't tell you is you really need a laser power meter to set the current correctly, but you can get close without one just keep it slightly lower than full power or the diode won't last long.

Just an example, I'm not recommending a seller or this item:

Yeah, but I have to wait until late July or August to get it here.  I'm looking for a US supplier, or someone like Amazon Prime where I can get it delivered in days and not weeks, or months. The only alternative seems to be to pay an extra $50 in shipping to get a $7 board here any faster

You can buy from US sellers, either on ebay or Amazon but cost is higher ($30).

Search for "5A Laser Diode Constant Current Driver"

Example:
