Quick Overview
The DIYables ESP32 Development Board 38-Pin Wide Version is a powerful microcontroller board built around the ESP-WROOM-32 module, featuring a dual-core Tensilica LX6 processor running up to 240 MHz with integrated 2.4 GHz WiFi and Bluetooth connectivity. The wide 38-pin layout provides full access to all available GPIO pins, making it ideal for projects that require extensive peripheral connections such as sensors, displays, relays, and expansion modules. The USB Type-C interface paired with the CP2102 USB-to-Serial chip ensures stable power delivery and reliable data transmission for programming and serial communication.
The board exposes rich I/O resources including multiple GPIO, ADC, DAC, UART, SPI, I2C, PWM, and capacitive touch sensor channels. The wide form factor is designed to fit standard breadboards on both sides without blocking any pins, allowing full use of all 38 pins during prototyping. Onboard 3.3V regulation accepts 5V USB input, and the CP2102 chip provides automatic driver support on most operating systems for plug-and-play programming.
Fully compatible with Arduino IDE after installing the ESP32 board package, as well as ESP-IDF and MicroPython for flexible development options. Ideal for smart home automation, wireless control, robotics, IoT sensor networks, web servers, and embedded system applications.
