Product Details
Simplify Prototyping with the RJ45 Connector MagJack SparkFun
Integrating ethernet into a breadboard is often difficult because standard jacks do not fit the grid. The RJ45 Connector MagJack SparkFun solves this issue by breaking out every essential pin. Since it uses a standard 0.1 inch pitch, you can plug it directly into your project. This board saves you time so you can focus on your code instead of complex wiring.
Advantages of the BOB 10321 RJ45 Connector
The BOB 10321 RJ45 Connector includes built-in magnetics to filter out signal noise. This feature is vital because it ensures a stable data link for your microcontroller. While other breakouts require external transformers, this all-in-one solution keeps your project compact. Also, the integrated status LEDs provide immediate visual feedback on your network activity.
Industrial Grade Reliability
This RJ45 Connector MagJack SparkFun features a fully shielded housing to block electromagnetic interference. The PCB is made from high-quality materials that withstand frequent plugging and unplugging. Specifically, the breakout pins are clearly labeled for easy identification. Consequently, the RJ45 Connector MagJack SparkFun remains a favorite for both students and professional engineers.
