ZC Bare PCB

ZC Bare PCB

Provides zero-cross signal to "the ESP Thing," Arduino, Raspberry Pi, Ren-C/595 or Grinch systems.

More details

A zero-cross signal is required to add proper dimming control to Arduino, Raspberry Pi, Olsen595 or Grinch controllers or to the "ESP Thing" if you want to control A/C lights. The ZC board needs only a few components: two 15K 1/2-watt resistors, a 6-pin DIP socket, an H11AA1 IC and appropriate screw-in terminal blocks.
