ESP Relay Board Design
Thought for 2 sec
I haven’t made any project changes yet. Your project is still empty: no components, nets, schematic, or PCB layout have been added.
You’re asking for an ESP-based board with 10 relays and 10 push buttons mounted on the back. To proceed when ACUs are available, the main items to define are:
- ESP choice: ESP32 module/devkit vs bare ESP32 module.
- Relay specs: coil voltage, contact rating, mechanical relay vs solid-state relay.
- Power input: USB-C, DC barrel jack, screw terminal, or another supply.
- Button behavior: each button controls one relay locally, reports to ESP firmware, or both.
- PCB/mechanical constraints: board size, relay terminal orientation, button placement on the back side.
Suggested next steps once ACUs are available:
- Create the schematic with ESP32, 10 relay driver channels, flyback protection, relay connectors, and 10 rear push buttons.
- Add the power supply sized for the relay coils and ESP32.
- Define front/back PCB placement: relays and terminals on one side, push buttons on the back.
- Run ERC/DRC and prepare a bring-up checklist.
