Need pcb design to have mini relays with esp32s chip and hilink ac to dc converter

Engineer asked May 28,2020
I need pcb design to have Hilink ac to dc converter with ESP32s and mini/micro relay (2ch/4ch/8ch) and it should work similar to sonoff 4CH R2 relay. Is it possible to have everything on single pcb so that it should occupy minimum space ? Hilink ac to dc converter will supply power to ESP32s chip so that we don't need any external power supply.
