This is weird, two drivers so far and I’m not getting any power through them. I’m using a power supply to test. If I touch the + and - on the mcpcb, leds light up. If i alligator clip the power supply to the driver, no power.
After the driver is hooked up, are you sure the LED’s aren’t on? First mode maybe ML, and with something like this driver on a triple, ML will be very very low.
Maybe you were sent a version with electronic switch firmware? Have you tried putting a switch on pin 2? I can’t remember if my eswitch version flashed the LEDs when connected to power.
I have had problems with the thinner boards (1.2mm PCB’s)not making ground, probably why he is going back to the 1.6mm boards, the retainer ring would bottom out and the driver felt tight but wouldn’t be tight enough to make ground.
Assemble everything outside the pill and see if it works….touch your power supply leads to the spring and ground ring on the driver momentarily to see if it works…
For what it is worth I have ordered 7 drivers from Richard and none of them were defective, there is something else wrong. Get a multimeter out and test the voltage to the microcontroller. If there is voltage to the microcontroller but not the pin that controls the FET then it is a firmware/switch issue.
So I have ordered two of these drivers that came with a capacitor installed instead of the pads being bare, and no note. When I contacted Richard he said the capacitor helped with noise, this was last year some time.
Crap guys, so thanks for narrowing it down. Apparently I ordered all the drivers with biscotti firmware. I should be able to reflash with guppy or other firmware right?
