Single mode KD 7135

So I thought my removing the MCU I could convert KD V2 7135 to single mode. It is not lighting up.

Is there anything I need to change to make this board a single mode? I still want to limit current with the 7135’s, just no modes other than high.

Same routine, jumper from LED+ (Red wire) to the AMC7135 Vdd pin. When looking at the AMC7135 with single Gnd tab up and three pins down, the Vdd pin is on the lower right. If the protection diode is still in place, jumpering from the diode on the other side of the Red wire will afford reverse batterry protection :slight_smile: .

Ah, my solder to the vdd wasn’t a good bridge. Now it works, thanks
