Click to zoom
Quick Overview
The DIYables ESP32 38 Pin Wide Board and Screw Terminal Breakout Board Set pairs an ESP-WROOM-32 38 pin wide ESP32 development board with its perfectly matched screw terminal breakout board. The breakout board is designed specifically for 38 pin wide ESP32 boards that have screw holes and top pin labels — both products in this set are guaranteed to fit together out of the box for immediate use.
The ESP32 board features the ESP-WROOM-32 dual-core microcontroller with integrated WiFi and Bluetooth, a USB Type-C interface, and a CP2102 USB-to-serial converter for reliable Arduino IDE programming and power delivery. The breakout board expands all 38 GPIO pins into 3.96mm screw terminal blocks and 2.54mm pin headers, enabling secure, solder-free wiring to sensors, relays, displays, and other peripherals.
Ideal for IoT prototyping, smart home automation, sensor integration, relay control, data logging, robotics, and any embedded project that benefits from stable, organized wiring on an ESP32 38 pin wide platform.
Key Features
- Perfect Matching Set — ESP-WROOM-32 38 pin wide ESP32 board and screw terminal breakout board are designed to fit together exactly with matching screw holes and top pin labels
- ESP-WROOM-32 Dual Core — ESP-WROOM-32 chip delivers dual-core processing with integrated WiFi and Bluetooth for wireless IoT and embedded applications
- USB Type-C with CP2102 — USB Type-C port and CP2102 USB-to-serial converter provide stable power and reliable data transmission for programming and serial monitoring
- 3.96mm Screw Terminal Blocks — Breakout board provides 3.96mm pitch screw terminals for strong, secure, tool-based wire connections on all 38 GPIO pins
- 2.54mm Pin Header Interface — Dual 2.54mm pin header rows on the breakout board offer standard breadboard-compatible pin access alongside screw terminals
- 38 Pin Wide GPIO Access — Full 38 pin wide layout exposes all ESP32 GPIO, ADC, DAC, I2C, SPI, UART, and PWM pins for maximum peripheral connectivity
- Top Pin Labels — Breakout board features top-side pin labels for easy identification of each GPIO during wiring and development
- Arduino IDE Compatible — Both boards support Arduino IDE, MicroPython, and ESP-IDF development environments
- Important Compatibility Note — Breakout board works only with 38 pin wide ESP32 boards that have screw holes and top pin labels; not compatible with other ESP32 form factors
- Versatile Applications — Suitable for IoT prototyping, sensor integration, relay control, home automation, robotics, data logging, and organized multi-peripheral wiring
