SmartLED & Pinball Power Board v1

Overview

SmartLED v1 is a modular, ATX-powered breakout board designed for ESP32-based lighting, solenoid, and accessory control projects such as:

• Virtual Pinball Machines
• Holiday Light Shows
• Aquarium Automation
• Home Decor Lighting Systems

Features

🔌 ATX/Mini-ITX Power Supply Input

• Standard 24-pin ATX connector
• PS_ON# control via MOSFET (GPIO or jumper selectable)
• Uses +5VSB to power ESP32 independently of main rails

🧠 ESP32 DevKitC Integration

• Supports 30-pin DevKitC boards
• Powered by +5VSB with onboard regulation
• Breakout header for unused GPIOs

💡 Buffered LED Outputs (8x)

• 3-pin JST outputs with:
  • AHCT125 level shifters (3.3V to 5V)
  • Selectable 5V or 12V via jumper
  • Fused output per channel

🧰 Dual Terminal Access

• Breadboard header (J10) and cabinet terminal block (J11)
• Shared pinout, use either or both

🧩 GPIO Expansion

• I²C header (GND, VCC, SDA, SCL)
• Additional GPIOs for sensors, encoders, buttons, etc.

🔋 MOSFET Driver Sockets

• 2–4 TO-220 MOSFET slots (e.g. IRLZ44N)
• Gate control via GPIO or jumper
• Voltage selectable (5V/12V AUX)
• For solenoids, fans, relays, motors, etc.

🔌 Power Outputs

• USB-C / Micro USB 5V outputs
• 5V/12V Barrel jack outputs
• Drive external Pi, LED drivers, amps, etc.

⚡ Cabinet Power Switch Output

• Optional switched line to control cabinet-wide power
• Triggered via ESP32 or logic jumper

Optional / Phase 2 Ideas

• Break-off compact section
• Raspberry Pi header (Zero/Full support)
• OLED display pinout for power/usage stats
• Software-based PSU shutdown/watchdog

Design Goals

• One ATX cable powers your entire rig
• Clean, modular, safe wiring
• Minimalist or advanced builds supported
• Great for compact lighting builds or full-featured pinball control systems
