ESP32 38-Pin Development Board Type-C - ESP-WROOM-32 Wi-Fi & Bluetooth
Couldn't load pickup availability
Upgrade your IoT workflow with the modern standard. The ESP32 38-Pin Development Board takes the immense dual-core processing power of the standard ESP-WROOM-32 module and wraps it in a heavily updated, maker-friendly package. By ditching the fragile Micro-USB port in favor of a robust USB Type-C connector, this board ensures your cables plug in perfectly on the first try and withstands the physical wear and tear of daily prototyping.
Maximum I/O and Ultimate Stability Unlike standard 30-pin variants, this upgraded board breaks out 38 individual pins. This provides you with maximum access to the ESP32's internal peripherals, giving you more GPIOs, analog inputs (ADCs), capacitive touch pins, and power connections for complex builds. To make wiring simple, every pin function is cleanly printed directly on the bottom silkscreen.
Furthermore, cheap clone boards often use unstable USB-to-serial chips that cause driver nightmares. This board utilizes the premium Silicon Labs CP2102 chip. The CP2102 is renowned for its rock-solid driver stability across Windows, Mac, and Linux, ensuring your code uploads flawlessly without frustrating COM port errors.
Compact Dimensions for Breadboarding Despite the high pin count, the board maintains a highly efficient footprint, measuring exactly 51.0mm in length and 25.5mm in width. It features an onboard 3.3V low-dropout (LDO) voltage regulator, allowing you to easily power the 3.3V logic from a standard 5V USB source.
