During the preparation for tindie store, I quickly write a demo program, showing JPY/USD currency. This program is greatly based on the source released at this website (I would thank the author), which is written for ESP8266. The source for ESP8266 is almost compatible with RTL8710 and we can enjoy RTL8710, as same as ESP8266. My Arduino sketch is uploaded to github. and this all-in-one board is on sale at tindie!
