Waveshare ESP-12F WiFi Module Based on ESP8266

Description

Overview
1. The ESP-12F is a WiFi module based on ESP8266, with built-in 32Mbit Flash, in the small SMD22 package. There're also onboard PCB antenna and metal shield. In short, it's a small form factor and fairly high cost effective WiFi module.
2. With the pre-flashed AT firmware, you can control the module through UART AT commands easily. The module integrates MCU inside, supports other developments like Lua/Micropython/Arduino to achieve flexible and fast prototyping, make it easy to integrate the module into IoT applications.

Features
1. 802.11b/g/n Wi-Fi+BT SOC
2. Integrated Tensilica L106 ultra-low-power 32-bit micro MCU, run at 80 MHz and 160 MHz frequency, supports RTOS
3. Built-in 1-ch 10 bit high precision ADC
4. Supports UART/GPIO/ADC/PWM/I2C
5. SMD22 package
6. ntegrated Wi-Fi MAC/ BB/RF/PA/LNA
7. Supports multi sleep modes, deep sleep current as low as 20uA
8. UART baudrate up to 4Mbps
9. Embedded Lwip protocol stack
10. Supports STA/AP/STA+AP operation mode
11. Supports Smart Config (APP) / AirKiss (WeChat), one key networking
12. Supports UART local firmware upgrade and/or remote firmware upgrade (FOTA)
13. AT commands for getting started fast
14. Supports secondary development, integrated Windows / Linux environment
