Description

The ESP32 38-Pin Breakout Expansion Board is an indispensable utility board designed to solve the breadboard spacing problem common to standard ESP32 development modules. Standard 38-pin ESP32 boards typically span across breadboards, leaving no room for jumper wire connections. This adapter shield breaks out every single pin into a heavy-duty screw terminal block and a matching male pin header row.

Equipped with a robust dual power supply system, the board features a standard 5.5mm × 2.1mm DC Barrel Jack accepting 6.5V to 16V DC input, as well as terminal block power inputs. The onboard voltage regulator safely powers the attached ESP32 unit while supplying stable power for external sensors, relays, and actuators.

Technical Specifications

Key Features & Highlights

• 38-Pin Socket Alignment: Engineered to fit standard 38-pin ESP32 development boards with precise pin spacing.

• Heavy-Duty Screw Terminals: Provides vibration-proof, secure wire terminations for long-term field deployments and industrial IoT nodes.

• Dual Power Input System: Powered directly via external DC Barrel Jack (6.5V–16V) or via terminal connectors, removing power load from USB ports.

• Parallel Header Extensions: Features both screw terminal blocks and duplicate male headers for simultaneous jumper wire or logic analyzer testing.

• Rigid FR-4 PCB Design: Double-sided copper plating with silkscreen pin labeling ensures long-term resistance to electrical wear and mechanical strain.

Common Applications

• Industrial IoT monitoring gateways and field-deployed sensor networks.

• Smart home automation control panels and relay interface boxes.

• Robotics motor control setups and embedded hardware prototyping.

• Permanent installation of ESP32 projects in DIN-rail or wall-mount enclosures.

What’s Included in the Box

• 1 × ESP32 Breakout Board Expansion Module (38-Pin Version)

  (Note: ESP32 Development Board sold separately).
