2015 最新產品 Arduino Ethernet Rev3 WITH PoE 意大利原廠 – 已經內含PoE模組支援網路供電 Switch


Arduino的 Arduino Ethernet Rev3 是一種基於ATmega328(微控制器板數據表)。它有14個數字輸入/輸出引腳,6個模擬輸入,一個16 MHz晶振,一個RJ45接口,電源插孔,ICSP標頭和一個復位按鈕。注意:引腳10,11,12和13是留給接口與以太網模塊,不應以其他方式使用。這減少了可用引腳的數量為9,用4可作為PWM輸出。通過以太網模塊的可選功率可以被添加到該板為好。以太網從其它電路板的不同之處在於它不具有板載USB至串口驅動芯片,但有一個WIZNET以太網接口。這是關於以太網屏蔽發現相同的接口。板載microSD卡閱讀器,它可用於存儲文件用於服務在網絡上,是通過SD圖書館訪問。

Arduino Ethernet Rev3 WITH PoE 意大利原廠 – 含PoE模組


The Arduino Ethernet is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins, 6 analog inputs, a 16 MHz crystal oscillator, a RJ45 connection, a power jack, an ICSP header, and a reset button.

NB: Pins 10, 11, 12 and 13 are reserved for interfacing with the Ethernet module and should not be used otherwise. This reduces the number of available pins to 9, with 4 available as PWM outputs.

An optional Power over Ethernet module can be added to the board as well.

The Ethernet differs from other boards in that it does not have an onboard USB-to-serial driver chip, but has a Wiznet Ethernet interface. This is the same interface found on the Ethernet shield.

An onboard microSD card reader, which can be used to store files for serving over the network, is accessible through the SD Library. Pin 10 is reserved for the Wiznet interface, SS for the SD card is on Pin 4.

The 6-pin serial programming header is compatible with the USB Serial adapter and also with the FTDI USB cables or with Sparkfun and Adafruit FTDI-style basic USB-to-serial breakout boards. It features support for automatic reset, allowing sketches to be uploaded without pressing the reset button on the board. When plugged into a USB to Serial adapter, the Arduino Ethernet is powered from the adapter.

The Revision 3 of the board introduces the standardized 1.0 pinout, that consist in:

  • added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, this will the opportunity to shield that use i2c or TWI components to be compatible with all the Arduino boards;
  • the IOREF that allow the shields to adapt to the voltage provided from the board. Shields that use the IOREF pin will be compatible both with the board that use the AVR, which operate with 5V and with the Arduino Due that operate with 3.3V. Next to the IOREF pin there is a not connected pin, that is reserved for future purposes.
