Thanks a lot. Initially when I get this driver, I checked and found that it has three working modes, and the highest measured current is 350mA, voltage is 3.68 v. However, this driver when connecting with blue diode, it only works at low levels, only about 200mW and works well in all three modes of high, medium, and flashing. I thought I mistakenly "this driver only for red," and I began work on a red laser. But, when checking out, it works very well, very steady current. When I assembled the host, red laser diode of me died instantly. I think it touched somewhere, I do and also as before. Then the next day, I try to check by test load, short-Mazz 2 wire (-) together is a surprise, jumped to 1170mA current enough to finish 1W blue laser. Therefore, I recommend that you do have problems with AK007, you connect the "-" of the circuit below with the above wires are available, however, it lost the working mode .
