TIPS about "bricking": some "WiFi-busy" binary leads to "unable to upload binary" In order to escape, please connect (D8)GC0 to ground during power-on cycle and upload new binary. After finishing upload, disconnect the wire from D8 to ground

**NOW this board is supported by Realtek's Arduino IDE environment. Just add

https://github.com/Ameba8195/Arduino/raw/master/release/package_realtek.com_ameba_index.json

in Arduino IDE preference and install board support version 2.0.0 is enough! Please see a bit more details about it! **

What is it?

ARM based Wifi module (RTL8710) with CMSIS-DAP just in single board. After setting environment, we can program and make IoT thing as we wish by very popular Arduino language.

Why did you make it?

Programming Cortex-M3 is in general not easy for beginner. But wonderful open source well-made Arduino implementation of RTL8710, RtlDuino is released on github. I understand this environment has a very nice possibility of making IoT thing in very easy way at world standard ARM architecture. But not as same as ESP8266, we need some programmer (CMSIS-DAP or J-link) and I quickly made CMSIS-DAP embedded prototyping board .

What makes it special?

• We don't need any extra, just connect USB cable is enough.

• Arduino IDE compatible and now officially supported by Realtek's environment. Please see how to arrange programming environment

• I2C and SPI enabled, meaning we can connect sensors and display

• Of course WiFi enabled. Your board is ready to connect to the world!
