**This new **[**Arduino **](https://www.industriaembebidahoy.com/category/arduino/)[**Ethernet **](https://www.ntdhoy.com/category/ethernet)[**board**](https://www.industriaembebidahoy.com/category/arduino/)** with **[**PoE**](https://www.ntdhoy.com/category/poe)** support titled Squama, widely supports the **[**design**](https://www.ntdhoy.com/category/diseno)** of new applications.**

[**Longan Labs**](https://www.industriaembebidahoy.com/category/longan-labs/) begins development of the** Squama** seriesof Ethernet cards for Internet of Things ([IoT](https://www.ntdhoy.com/category/iot) ) applications. The first model in this family is the** Squama Ethernet – **[**Arduino**](https://www.ntdhoy.com/category/arduino)** W5500 Ethernet Board** , which integrates with a high-performance** Cortex M0 +** based** MCU** and a[** W5500**](https://www.comunicacionesinalambricashoy.com/chips-ethernet-para-el-internet-de-las-cosas/) Ethernet control chipto support the design of Ethernet-based applications.

The card is integrated with the chip [**ATSAMD21G18**](https://www.diarioelectronicohoy.com/controlador-para-motor-de-paso-de-4-ejes/) 32 bit **Atmel** which is based on the microcontroller Cortex-M0 + of **up to 48 MHz** . The chip is characterized by a **256 KB** system self-programming flash memory , a **32 KB** SRAM memory and **power-on reset** ( **POR** ) and **brown-out detection** ( **BOD** ), which usually disables the microcontroller that monitors the [voltage](https://www.ntdhoy.com/category/de-tension) level of the power during operation.

The [**interfaces**](https://www.ntdhoy.com/category/interfaces) comprise SPI MODE 0, 3, a Grove connector for I2C and UART, and an [RJ45](https://www.ntdhoy.com/category/rj45) connector .

With a format of **62 x 30 mm** and 15 g (without PoE) or 20 g (with PoE), it is also distinguished by a supply voltage of **5 V** via USB and **48 ~ 57 V** via PoE, an output current 2 **Amp** , a **WS2812B **[LED,](https://www.ntdhoy.com/category/led) and reset and user buttons.

The hardware is designed to use a **bootloader** like **Arduino Zero** that allows the **Arduino IDE** to be used in programming tasks.

In order to work with this card, the Arduino IDE needs to be installed on **Windows, macOS and Ubuntu** based systems . From the **menu** , it is possible to go to the “preferences” search for “Longan”. In this way, you can download the latest SAMD Longan card and then select the Squama Ethernet card.
