Highlights

• 🔌 Full GPIO access with LED status indicators – Each of the 44 GPIO pins features a dedicated LED displaying the current logic level (HIGH/LOW) in real-time. Perfect for rapid debugging without an oscilloscope—ideal for makers, developers, and students.
• ⚡ Powerful 3A dual-voltage power supply – Two integrated JW5357 DC-DC converters simultaneously deliver 5V/3A and 3.3V/3A from a 7–18V DC source. Ample power for motors, servos, LED strips, and demanding sensors.
• 🔧 Flexible peripheral connections – Each GPIO row offers both a 3-pin 2.54mm header (S/V/G) and a screw terminal for secure, vibration-resistant connections—perfect for field installations and robotics projects.
• 🛡️ Robust protection circuitry – Equipped with reverse polarity protection (SI2302 MOSFET), back-feed protection between the 5V DC-DC and USB 5V rails, and an overvoltage-tolerant input stage (7–18V). Protects your ESP32-S3 and peripherals from damage.
• 🔀 Selectable V-rail voltage (3.3V / 5V) – A simple jumper selects the supply voltage for all peripheral pins. Compatible with 3.3V sensors (I²C/SPI) and 5V components like servos, relays, and WS2812B LEDs—no additional level shifter required.
