Açıklama

Features

• Powerful CPU: ARM Cortex-M0+ MCU running at up to 48MHz (ATSAMD21G18)
• Flexible power manual: PoE or Type-C
• Various Hardwired TCP/IP Protocols support: TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoE
• Flexible compatibility: Compatible with Arduino IDE

Description

Squama is a series of products. This series of products have a standard appearance, with a general size of 62x30mm. The series integrates an MCU and peripherals with a communication function, which is suitable for IoT-related applications.

Squama Ethernet is the first product in the Squama series. Squama Ethernet integrates a high-performance microcontroller based on Cortex M0+ and an Ethernet control chip W5500, which can be used by users to develop Ethernet applications.

WS2812 LED and user buttons are also integrated on the board, which can facilitate some interaction. More importantly, Squama Ethernet supports PoE (Power Over Ethernet), which makes the wiring more concise. Only one network cable is needed to complete signal transmission and power supply.

Squama Ethernet uses the Arduino Zero like bootloader, you can use Arduino IDE to develop your application easily.
