On this development board, the DUT uses the Ethernet MAC controller chip CD1001A-Q and the adjustable LDO chip CD1117C-ADJ launched by Coreadc Micro, which are used to evaluate the functions of the CD1001A-Q chip.

The USB interface is used to connect the serial port debugging software for sending and receiving data.

The RJ45 interface serves as the network cable interface for network transmission and testing of related functions.

Pin connections are led out through pin headers, facilitating debugging and extended testing.

A TQFP48 test socket is integrated on the board, allowing flexible chip replacement without welding.
