Better is use some kind buck converter to remake 12v to 3v
Hi, thanks for input, I use 12v-5v mean well converter :)

So I managed the blinking after third inverter with running +V to inverter which outputs -V. Then i hooked that to -V for group of TLC. So -V comes from inverter and +V comes from 5V converter. Now the problem is after 10LEDs it starts to blink again. I measured voltage and it seems like inverter outputs only 3V, then it drops TLC group and blinks. Am I right about that? Is there a way to amp up that voltage back to 5V ?
