Description

The ESP32-C6-WROOM-1U module is a versatile wireless module that supports Wi-Fi, IEEE 802.15.4, and Bluetooth LE connectivity. It offers a range of powerful features to meet various application needs. The module is equipped with the ESP32-C6 chip, which features a RISC-V 32-bit single-core processor.The module provides a rich set of peripherals, including SPI, UART, I2C, and up to 23 GPIO pins, enabling seamless integration with other devices and sensors. This versatility makes it well-suited for a wide range of applications such as smart homes, industrial automation, healthcare systems, and consumer electronics.

With its high-performance capabilities and reliable wireless connectivity, the ESP32-C6-WROOM-1U module offers an excellent solution for developers and engineers seeking to create innovative and connected products.

Compared to the ESP32-C6-WROOM-1, the ESP32-C6-WROOM-1U removes the onboard antenna. On the one hand, this change reduces the module's size, making it more suitable for smaller products. On the other hand, it introduces an IPEX interface, which allows users to connect an external antenna with stronger gain. This enhancement enables longer-distance signal transmission.
