GY-NEO-8M Ceramic Antenna Module

The GY-NEO-8M Ceramic Antenna Module with an external antenna is a high-performance GPS solution built on the renowned NEO-M8 series GNSS engine. This module supports concurrent reception of multiple GNSS systems, including GPS, Galileo, GLONASS, and BeiDou, ensuring precise and reliable positioning even in challenging environments. With a compact module size of 35.8mm by 25.6mm and a lightweight design at 17g, it is ideal for applications where space and weight are critical, such as drones and portable navigation systems.

The external ceramic antenna, measuring 28.3mm by 28.3mm, significantly enhances signal reception, allowing the module to maintain accurate positioning in areas with weak signals or urban canyons. The GY-NEO-8M is equipped with versatile interfaces, including UART, USB, SPI, and I2C, providing flexibility for integration into various GPS-dependent projects. Whether you're developing a navigation system, drone, or any other GPS-based device, this module delivers the accuracy, stability, and ease of integration you need to ensure success.

For those seeking a more integrated solution, the GY-NEO-8M with an onboard antenna offers an all-in-one package that simplifies installation without compromising performance. Weighing slightly more at 18g and with dimensions of 38.9mm by 25.2mm, this version is still compact and lightweight, making it ideal for projects with limited space. The onboard ceramic antenna is designed to provide excellent signal reception, making it a reliable choice for high-precision GPS tracking in a variety of conditions.

Both versions of the GY-NEO-8M module offer superior performance, but the choice between an external antenna and an onboard antenna allows you to tailor the solution to your specific needs. Whether you require the flexibility of an external antenna for enhanced signal in obstructed areas, or the simplicity of an onboard antenna for streamlined integration, these modules deliver exceptional value and reliability. Invest in the GY-NEO-8M GPS modules today to elevate your project’s GPS accuracy and performance.
