Help with AliExpress Driver

Hello,

I want to build a Laser Pointer with the PLTB450B Diode. I ordered this Driver from AliExpress:

445nm 520nm 1W 1.6W 3W Laser Diode Drive Driver Board PCB 6 14V Voltage Input-in Replacement Parts from Consumer Electronics on Aliexpress.com | Alibaba Group

I send them a massage that i need it for a 1.6w Diode.
on the one side they solderd a R470 resistors in parallel (ontop of) the the R200 resistor. And they send 3 R300 resistors. Do they need to be solder all in parallel on the other side on the free solder Pads ? When i solder in one of the R300 resistors the current is to hight (over 200ma but the Diode is rated for a current of 167ma. Does soldereing the resistors in parallel in a lower Output current ?

I hove you understand my Problem and someone is able to give me an advice.

Thanks, Jonas

first you should introduce yourself in the welcome section and tell about your location.

as for your problem i don't get the part of 167ma,you need around 1.5-1.8A to drive this diode over 1.5w

Exactly.

5oAwes0me--look here at what mA and voltage produce what output with a PLTB450
