RTLDuino is an Arduino Compatible WiFi IoT Board based on Realtek RTL8710AF WiSoC. It with many of the same functions as ESP8266, but with an ARM Cortex M3 core instead. The board is actually based on the B&T RTL-00 module. This is obviously quite easier to use since you don’t need to solder any cables to connect a USB to TTL board since RTLduino is equipped with CH340g and a micro USB port.
WiSoC – Realtek RTL8710AF ARM Cortex-M3 micro-controller @ 83 MHz
Connectivity – 802.11 b/g/n WiFi
USB – 1x micro USB port for programming and power
Expansion – 2x 16-pin breadboard-friendly headers with GPIOs, UART, SPI, I2C, PWM, I2S, power signals
