Expansion board (shield) for ESP32-DEVKit, thanks to this expansion board you can easily control up to six channels on which you have connected neon tubes. You can use any color combination, because all of them are powered from the AC input - this voltage can be from 50 to 110 V.
Channels:
CH1 - GPIO12
CH2 - GPIO13
CH3 - GPIO14
CH4 - GPIO25
CH5 - GPIO26
CH6 - GPIO27
The ESP Neon Shield can also power the LaskaKit ESP32-DEVKit control board itself via a DC barrel jack.
