Waveshare ESP32-S WiFi+Bluetooth Module Based on ESP32

Description

Overview
1. The ESP32-S is a wireless module based on ESP32, supports WiFi and Bluetooth 4.2, with built-in 32Mbit Flash, in the SMD38 package. There're also onboard PCB antenna and metal shield. In short, it's a small form factor and fairly high cost effective wireless 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.

3. Built-in two 12 bit SAR ADCs, up to 18 channels
4. Supports UART/SPI/I2C/SDIO/GPIO/ADC/PWM
5. SMD38 package
6. Supports OpenOCD debug interface
7. Supports multi sleep modes, deep sleep current as low as 6.5uA
8. UART baudrate up to 4Mbps
9. Embedded Lwip and FreeRTOS
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
