ESP32 Type-C 38 Pin Dev Board – Dual Core WiFi+BT

ESP32 2 Type-C Development Board – 38 Pin CP2102 WiFi & Bluetooth

Product Description

The ESP32 2 Type-C Development Board (38 Pin Version) is a versatile dual-core microcontroller board designed for IoT, robotics, automation, wireless communication, smart home, and embedded projects. It combines Wi-Fi, Bluetooth, a dual-core processor, and 38 GPIO pins in a compact development platform.

The board features a USB Type-C connector with an onboard CP2102 USB-to-UART bridge, providing convenient programming, serial communication, and power connectivity.

Dual-Core Processing

The ESP32 processor provides dual-core 32-bit processing with clock speeds from 80MHz up to 240MHz, allowing the board to handle a wide range of control, communication, and data-processing tasks.

Its low-power capabilities, including a specified deep-sleep current of less than 5µA, make it suitable for battery-powered and wearable applications.

Wireless Connectivity

Wi-Fi

Integrated 802.11 b/g/n Wi-Fi enables wireless internet connectivity for remote monitoring, cloud communication, web servers, and IoT applications.

Bluetooth

The board supports Bluetooth 4.2 BR/EDR and BLE, allowing communication with smartphones, sensors, computers, and other compatible devices.

USB Type-C

The modern USB Type-C connector provides a reversible connection for programming, serial communication, and power.

Extended 38-Pin Interface

The 38-pin configuration provides extensive access to GPIO and peripheral functions, including ADC, DAC, PWM, SPI, I2C, UART, capacitive touch, and other interfaces.

This expanded pinout makes the board suitable for projects requiring multiple sensors, displays, actuators, communication modules, and control devices.
