ESP-12L WIFI MODULE V1 1. Product overview The ESP-12L WiFi module was developed by Ai-Thinker Technology. The core processor ESP8266 integrates the industry-leading Tensilica L106 ultra-low-power 32-bit micro MCU in a small package with 16-bit Lite mode, clocked at Supports 80 MHz and 160 MHz, supports RTOS, and integrates Wi-Fi MAC/BB/RF/PA/LNA. The ESP-12L WiFi module supports the standard IEEE802.11 b/g/n protocol, a complete TCP/IP protocol stack.
