Description

The processor ESP8266 integrates the industry-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.
It supports RTOS, integrated with Wi-Fi MAC/BB/RF/PA/LNA. Onboard comes with curved antenna.
This development board is a standalone network controller, which can add networking function to those existing devices.
It 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.
The board can be powered via the USB port, or with an external power supply (DC 7-12V), or powered by the female headers Vin/GND (DC 7-12V).
