What

This device is following this project LINK for ESPHome based AUX AC control. This project consists of full documentation for 2 layers PCB, equipped with power supply and ESP32 S3 WROOM 1 device.

Full documentation is available at our GITLAB:
GITLAB CIRCUIT-ISSUES

SCH

The schematic LINK was generated using KiCad, consists of:

  • 5 pin 2.54mm connector
  • RP (reverse polarity) diode
  • SMPS based power supply (TPS562203)
  • EPS32 S3 WROOM 1
  • button for BOOT selection
  • resistors for UART protection

PCB

The resulting PCB has following features:

  • 2 layers PCB. 1.6mm thickness
  • 25x50mm (+connector overhang)
  • single side population
