An Alternative to ESP8266? Realtek RTL8710 ARM Cortex-M3 WiFi IoT Modules Sell for $2 and Up

ESP8266 WiFi modules initially stormed the maker market for IoT applications thanks to their low price, and later it became the dominant WiFi IoT platform for hobbyists thanks to its large community of developers. But technology progresses over time, and it’s always fun to look out for new solutions, and Realtek RTL8710 could prove to be an interesting alternative with its ARM Cortex-M3 processor @ 166 MHz, a little more user memory (48KB), audio support, faster WiFi performance, while still keeping a low price, as modules can be purchased for $3.90 on ICS station, a little more on eBay, and as low as $1.95 per unit on Aliexpress including shipping if you purchase 100 pieces or more. A Chinese website as a side-by-side comparison between Realtek RTL8710 and Espressif ESP8266, which I also found translated into English. Realtek RTL8710 Espresif ESP8266 Package QFN-48 (6×6 mm) QFN-32 (5×5 mm) CPU ARM […]
