ESP32 Relay Controller


The schematic is now wired. I’m verifying the netlist and ERC checks, including the 555 mandatory reset, control bypass, and supply decoupling connections.
Implemented the 9V hand-solderable red LED blinker schematic using a TI NE555P DIP-8, through-hole LED, slide switch, PP3 9V battery holder, axial resistors, and through-hole capacitors. The 555 astable is set to about 1.06 Hz with ~50% duty cycle, so the LED blinks roughly once per second; electrical connectivity checks are clean.
Open items:
  • PCB layout/routing is not done yet, so airwire DRC errors are expected.
  • Generic passives have through-hole packages and values, but not exact manufacturer part numbers yet.
Suggested next steps:
  1. Assign exact MPNs for the generic resistors/capacitors if you want a manufacturable BOM.
  2. Move into PCB layout: size the board, place the battery holder/switch/LED, then route.
  3. Add silkscreen labels for battery polarity, switch ON/OFF, and LED orientation.
create a circuit with esp32 , and 4 12v 230v relays, add on board 230v power supply the relay and controllers
No project changes were made for this new ESP32 mains-relay request. It requires several safety-critical decisions before implementation: relay contact current/load type, isolated AC/DC supply rating, ESP32 interface/control method, enclosure class, terminal style, and required regional safety standard; the current project remains the existing 9V 555 LED blinker.
Execution stopped because your ACUs ran out.
