RTL8710 Wifi Module is a low-cost wireless IoT platform based on Realtek RTL8710 ARM Cortex-M3 Processor 166MHz. It is tiny but could prove to be an interesting alternative with its stronger MCU, 1MB ROM, 512KB RAM, built-in 1MB Flash, and faster Wifi performance.

RTL8710 Wifi Module uses FreeRTOS as the go-to operating system and can be debugged and programmed using RealTek’s RTL8710 SDK over a micro USB connection. It packs up to 17 GPIO, up to 3 I2C, up to 2 PCM, 4 PWM, and two high-speed UART and one low-speed. For Wi-Fi, it has a speed of up to 150 Mbps over an 802.11n connection and a top speed of 54 Mbps over 802.11g. Detailed spec as below.

RTL8710 Wifi Module offers an even lower cost even stronger processor. So it helps to provide another better choice on WIFI IoT platform for makers, hobbyists, Hardware engineers and Software engineers, cheaper and more powerful.

  • Hi, i have a question about firmware of this module. Are those modules sold here pre-programmed with AT-command firmware? We are trying to communicate with module but it seems there is no FW. For communication with module we are using pin GB0 -UART_LOG_OUT and GB1 -UART_LOG_IN but there is no text output and it is not accepting any command on this UART. We were also testing UART0 (GC0,GC3 pins) with same result. Thank you

    I check connection according your picture and it seems ok. I was testing 2 modules and non of them communicates. It seems to me those modules are not programmed , no firmware. I was testing all pins by scope and no communication on any pin is visible. Are you sure those modules are delivered with firmware? Thank you.
