ENC28J60 Ethernet LAN Network Module

The ENC28J60 Ethernet Module utilizes the new Microchip ENC28J60 Stand-Alone Ethernet Controller IC featuring a host of features to handle most of the network protocol requirements. The board connects directly to most microcontrollers with a standard SPI interface with a transfer speed of up to 20MHz.

Specification

• ENC28J60 Ethernet chips, SOP28 package
• SPI Interface
• 2X5 connector, can be easily mounted with the MCU
• Power indicator
• Single Supply: 3.3 V
• PCB size: 55×36 mm

Technical Details

This module is based on resistive voltage divider design principles, It is capable of reducing the voltage of the input terminal connection five times

• You can use a 5V maximum voltage on the ADC side of the module so which allows for a maximum of 25V on the input side
• If 3.3V is used, the input voltage must not exceed 16.5V
• Because AVR chips use 10 bit ADC, the maximum resolution of this module is 0
• 00489 V (5V / 1023), so the voltage detection module detects minimum input voltage is 0.00489V? 5 = 0.02445
• Input voltage range: DC0-25V
• Voltage detection range: DC0.02445 V – 25V
• Voltage analog resolutions: 0.00489V
• DC Input: positive terminal connected to VCC, GND negative pole
• Output interface: ” ” then 5 / 3.3V, “-” then GND, “s” then the AD pin
