New 4 Channel Highside driver

[Badpip]

hello, I own one of your driver, but I have a problem...it's powered with 12V, max current is 1.2A per diode, all is working fine, but if I put the jumpers, the diodes stop lasing (even with 5V mod)...is that normal ?

That sounds strange - does it modulate correctly without the jumpers? Is it happening with all 4 channels?

PM me and we will work it out

Yes it modulate correctly without the jumpers, and no, on one channel it's doing nothing.
(I will pm you soon ;-) but now the driver is inside the laser..so it will not be easy to do some test.)

one thing to note on these drivers ,is the solder pads, make sure your soldering is good ie no bulging blob solder joints
as it is possible to create short circuits if you do.
the ground plain is very close to the pads, i had a short and did not notice and had problems.
might be and idea for future version to have a bigger gap than 1/4mm around each pad

Just curious why they are cheaper on EBAY at least I think, I get lost in the currency conversion sometimes but isn't 60Euro $75 usa dollar and this auction only $70? http://www.ebay.com/itm/Quad-Highsid...#ht_649wt_1203

Thomas,

I NEED the modified Quad Driver! My big projector is sitting open sans green waiting for my new DPSS which I can only drive with a single pump. I have a show in two weeks and I visit the post box each day only to leave disappointed (grinding my teeth). The postal Sx in each of our countries sucks. They lost the first drive and now this. Help!
