This 38-Pin ESP32 Development Board with Specialized 25.5mm Baseboard (Expansion Shield) is a precision-engineered prototyping kit. It is designed for the modern 38-pin version of the ESP32-DevKitC, featuring a narrow-profile baseboard that accommodates the 25.5mm pin spacing commonly found in the latest module iterations in 2025.
Product Description
The ESP32-DevKitC 38-Pin kit is a powerful, dual-core wireless platform optimized for high-density IO projects. By pairing the core ESP32-WROOM-32 module with a specialized 25.5mm width baseboard, this kit solves the most common frustration in IoT development: fitting the wide ESP32 board into a project without losing access to ground and power rails.
The expansion baseboard is a dedicated power and signal hub. It breaks out all 38 pins into clearly labeled “GVS” (Ground-Voltage-Signal) headers, allowing you to connect sensors and servos using standard 3-pin jumper cables. With an onboard DC Barrel Jack and integrated voltage regulators, this setup provides a stable 5V and 3.3V environment, preventing the “brown-out” resets often caused by powering peripherals solely through a computer’s USB port.
Key Features
- Precision 25.5mm Fit: Specifically designed to seat the 38-pin ESP32-DevKitC perfectly, ensuring all pins make a secure, low-resistance connection.
- Dual-Core Performance: Powered by the Xtensa® 32-bit LX6 processor (up to 240MHz), supporting simultaneous Wi-Fi and Bluetooth tasks.
- Professional Power Management: The baseboard accepts 6.5V to 12V DC input, regulating it down to clean 3.3V/5V rails for external hardware.
- “GVS” Header Layout: Every GPIO pin is grouped with a dedicated Power (V) and Ground (G) pin, drastically simplifying wiring for sensors and actuators.
- Hybrid Connectivity: Fully compatible with Wi-Fi 802.11 b/g/n and Dual-mode Bluetooth (Classic and BLE).
- Mounting Ready: The baseboard includes four 3mm mounting holes for secure installation in industrial control boxes or 3D-printed enclosures.
