ESP32 38-pin CP2102 USB-C Development Board

A high-performance, versatile development platform built around the advanced ESP-WROOM-32 chip from Espressif. It is a complete tool for building modern automation systems and Internet of Things (IoT) projects. This version features a wide pin layout-the spacing between pin rows is 25.4 mm, which is essential when choosing compatible expansion boards. Communication and programming are handled via a modern USB-C port paired with the highly reliable CP2102 converter IC.

The device offers tremendous programming flexibility. It works excellently as the main controller for Arduino, an alternative to the ESP8266, or a communication module extending capabilities for Raspberry Pi.

Benefits of using this module

• Integrated connectivity-Wi-Fi and Bluetooth in a single chip makes communication with almost any environment straightforward.
• Plenty of performance headroom-two cores at 240 MHz ensure smooth operation for demanding algorithms and hardware-accelerated encryption.
• Versatile powering-power via the USB-C port or dedicated 3.3V / 5V supply pins.
• Broad software ecosystem-full support for popular environments including Arduino IDE, PlatformIO, MicroPython, and ESP-IDF.
• Rich peripherals-many ADC channels and hardware support for common communication protocols on numerous GPIO pins.

Example applications

• Advanced weather stations with direct upload of readings to cloud servers.
• Network gateways collecting data from Bluetooth Low Energy sensors and exposing it over local Wi-Fi.
• Smart relay and lighting controllers for Home Assistant or openHAB ecosystems.
• Real-time audio streaming projects using the digital I2S protocol.
• Industrial predictive maintenance systems based on advanced signal processing.
• Web servers with graphical interfaces served on the local network.
