Product Overview:

In order to address the shortcomings of the Discovery F4100 USB 2.0 interface such as low data transmission and poor real-time performance, in order to meet the high-speed real-time data transmission requirements in areas such as PCB exposure and 3D printing, Feiguang Technology independently developed an N2D expansion module.
The N2D expansion module is perfectly connected to the Discovery F4100 through a high-speed expansion interface, eliminating the need for separate power supplies and making connection simple.
The N2D expansion module is an onboard RTL2812F chip that is adaptive to 10/100/1000M Ethernet and fiber optic networks. It supports multiple operating modes such as RGMII, GMII, RMII, and MII, and supports TCP/IP and UDP protocols.
