Note:There two choice to choose, W5500 board and W5500 shield ,please take an eye on of it ,make sure that you are choosen what you want!!!

Related Introduction About W5500 Network Shield

Special note: We used version 1.5.6 of the IDE during testing, which is not compatible with other versions of the IDE.

Keyestudio W5500 network shield comes with W5500 network module as core.
It can make as simple Web server, or write and read the High/Low level of digital pins, or analog value of analog pins via network control.It is compatible with both keyestudio UNO R3 and Mega 2560 R3 development board.
When using, stack the W5500 shield onto UNO board, and upload the program to control board, which can make a simple Web server.
You can quickly make your controller access to internet to build your network application.At the same time, it also supports mini SD card(TF card, maximum storage 1G) read and write.You can direct stack the W5500 Network shield onto control board, or stack other expansion boards on this Network shield.The shield has four 3mm fixing holes, easy to mount on any other devices

This DMX(RDM) shield is designed for Arduino. Its working voltage is 5V and has 0.5W power consumption.
It can transmit and receive DMX through Arduino so as to control speakers, light and smoke machine. If you get tired of the programming language, you also can use C language with the DMX（RDM）shield.

Working Principle

DMX（RDM）shield communicates via DMX. It can serve as the Master or Slave when you treat Ardunio as the controller of DMX. DMX shield is an add-on for the Arduino and the MAX485 chip can drive the circuit. DMX library is based on the USART library, which indicates TX and RX serial communication are applied. When the port of Arduino is connected to MAX485, the DMX device can communicate with Arduino.

The ReSpeaker 2-Mic Pi HAT V1.0 shield designed for AI and voice applications. It is a low power stereo Codec based on the WM8960.
There are two microphones on the shield for sound collection, three APA102 RGB LEDs, one user button and two connectors for application extension. The shield comes with a 2.54mm Grove cable

In addition, a 3.5mm audio jack or XH2.54-2P speaker output can be used for audio output.
With this shield, you can build a more powerful and flexible voice product that integrates Amazon Amazona voice services, Google Assistant, and more.

Note:After plugging in speaker module, the status of RGB LED is not stable; however,the status is normal when testing RGB.

Features

Support the Raspberry Pi 3B

Two microphones (Mic L and Mic R)

Two Grove connectors

One User-defined button

3.5mm audio interface

XH2.54-2P audio output interface

Note:The experiment is done with Raspberry Pi 3B. Yet other versions of Raspberry Pi may not be compatible.

Overview

• At the heart of Raspberry Pi Zero 2 W is RP3A0, a custom-built system-in-package designed by Raspberry Pi in the UK. With a quad-core 64-bit ARM Cortex-A53 processor clocked at 1GHz and 512MB of SDRAM, Zero 2 is up to five times as fast as the original Raspberry Pi Zero.

• Wireless LAN is built in to a shielded enclosure with improved RF compliance, giving you more flexibility when designing with Raspberry Pi Zero 2 W.

• All in the same tiny 65mm × 30mm form factor.

Package Contains

1. Raspberry Pi Zero 2 W x1
