What type of driver is this?

Well I have not been online in three years so I kind of forgot what happened to this driver. Anyway long story short I got around to testing it since I guess I destroyed it previously. The pot is not in the best condition, and I was wondering if I could replace the pot to get more current out of the driver.

Currently the max output is around 260mA , and lowest is 125mA.

Is it safe to replace the pot to boost the current? Or am I just going to end up blowing the driver?

Looks like a prototype of the rkcstr MicroDrive.

I actually was looking at them before to try and figure it out, It seems like only the one block matches up.

All the other pieces (resistors?) seem to be different?

The other components are the same. The difference between 2R7 and 3R01 will be compensated by the pot.

I suggest resolder the leads. They are very exposed. The loose wires could short and destroy the diode or driver.

the leads where the diode is meant to be?

So whats your opinion on removing/replacing the pot?

What output are you wanting to reach ? I'd suggest just to buy another driver, they're cheap enough

I was looking for something around 500ma, ended up buying a 1000ma driver so problem solved.
