IoT Base Platform with RaspberryPi, WIZ850io : Platform Device Driver

​I know RaspberryPi platform for IoT. Recently WIZ850io is announced by WIZnet. So I implemented a RaspberryPi application by Ethernet SW modification because I can handle a source code easily. You can test Platform Device Driver through RaspberryPi and WIZ850io. Please refer to the following step.

Step 1: Prepare Materials

Please refer to the following.

1. Raspberry Pi 3 Starter Kit

2. WIZ850io

3. UART2USB adapter

4. LAN cable

5. USB cable

Step 2: Hardware Connection

Please connect an USB, LAN cable, WIZ850io and UART2USB adapter.
You can get more HW info by the following site.
