ขาย โมดูลArduino Esp 8266 Wifi โล่กันกระแทกสําหรับ Arduino Uno R 3 Mega 3 . 3 V ราคาที่ดีที่สุด

Fully compatible with Arduino Uno, Mega, etc. using standard pin interface spacing. (unless the standard size arduino, such as Nano, Mini) Using the advanced 3.3V power chip (same as the official CC3000 expansion board power chip), the 3.3V provided in the Arduino board is more accurate, so that the ESP8266 works as the official cc3000 chip, no gap. A WiFi module power/service interface is introduced to facilitate developers to extend power and maintenance. The onboard ESP8266-12 industrial grade stable serial WiFi module uses an enhanced PCB antenna for better signal. The operation mode (such as operation mode and upgrade mode) of the ESP8266-12 industrial-grade stable WiFi module can be quickly switched by the DIP switch, and the serial port chip can be integrated to quickly write the firmware. Built-in 5V to 3.3V TTL level shifter prevents high voltage Arduino TTL levels from damaging the WiFi module. (General modules are not available) The onboard ESP8266-12 industrial grade stable WiFi module has a metal shield and is highly resistant to interference. All interfaces of the onboard ESP8266-12 industrial grade stable WiFi module are taken out at standard intervals, which is convenient for developers to develop in depth. With a stackable design, you can continue to add other modules on top for ease of use. The onboard 4 LEDs show the status of the ESP8266, which are PWR, DFU, AP, STA, and the operation mode is clear at a glance.
