I can design this, but I can’t execute project changes right now because there are no available ACUs for AI actions.
Current project state:
- New empty project: Sympathetic Pink P.K.E. Meter
- Components: 0
- Nets: 0
- No schematic or PCB work has been created yet.
What remains to be done:
- Define the system architecture for a 32-channel relay controller.
- Select the controller type, likely ESP32 with Wi-Fi or Ethernet MCU/module, depending on reliability needs.
- Add 32 relay driver channels with flyback protection.
- Decide relay ratings based on your desk lights/electronic loads: AC voltage, current, and whether loads are mains-powered.
- Add power supplies, isolation/clearance rules, connectors, protection, and status LEDs.
- Create firmware/server command interface plan, such as MQTT, HTTP REST, or WebSocket.
- Build schematic, PCB layout, and bring-up documentation.
Suggested architecture:
- ESP32 or Ethernet-enabled MCU
- 32 relay channels, preferably using relay driver ICs or transistor arrays
- Opto-isolated or well-separated mains/load side
- 12 V relay supply plus 3.3 V logic supply
- MQTT/HTTP command protocol from server
- Manual override and status feedback if needed
Before I design it, I’ll need these details:
- Are the desk lights/electronic systems AC mains or DC loads?
- What voltage/current per relay channel?
- Do you want Wi-Fi, Ethernet, or both?
- Should the relays be mechanical relays or solid-state relays?
- Is this for one PCB controlling all 32 relays, or multiple smaller boards?
