ITEM NAME:Keyestudio ESP8266-12F Wifi Development Board Module + USB Cable for Arduino Description: - Based on the ESP8266-12F WIFI module developed by Ai-Thinker. - Integrates the indrstry-leading Tensilica L106 ultra-low-power 32-bit micro MCU in a smaller package,with 16-bit Lite mode. The main frequency supports 80MHz and 160 MHz. - Supports RTOS, integrated with WI-FI MAC/BB/RF/PA/LNA.Onboard comes with curved antenna. - Standalone network controller, which can add networking function to those existing devices. - Has 11 I/O ports(4 of which can be used as PWM output),and all I/O ports operate at 3.3V. It also comes with an AD input interface,supporting the voltage range of 0-3.3V. -.Based on the ESP8266-12F WIFI module developed by Ai-Thinker. - Supports RTOS, integrated with WI-FI MAC/BB/RF/PA/LNA. - Has 11 I/O ports(4 of which can be used as PWM output),and all I/O ports operate at 3.3V.
