1 шт./лот мини ENC28J60 LAN Ethernet сетевой модуль 25 мГц Кристалл AVR 51 LPC 3.3 В

Product Description

Brand new and high quality.

chip board ENC28J60-I/SO.

the board 25MHZ crystal.

the network interface board HR911105A.

3.3 V power supply pin.

Size:5.9cm x 3.5cm - 2.32inch x 1.38inch.

Debug reminder:

1, the IP address of the computer to a network segment and module such as IP module 192.168.1.2, IP computer set: 192.168.1.3; 192.168.1 is the 3 section;

2, cross the network cable connected to the mouth of the computer network module and mouth; (that is, the cable network 1 3,2 cross, and then do not understand that there are pictures Baidu);

3, the module and the MCU connection should pay attention to the connection of each line is reliable (the surface is not even connected to the good);

4, and the MCU port IO to confirm that is right;

5, the program recompile, download, confirm whether to download! STM32 and 51 IO
