ESP8266 serial ESP-01 WIFI Wireless Transceiver Module - IOT

  • Sale
  • Regular price Rs. 210.00


ESP-01 ESP-8266 is an ideal choice for hobbyist to start experimenting with IOT. The dimension of this module is 25mm x 15mm, with simple pin connections (standard 2×4 pin headers), using serial TX/RX to send and receive Ethernet buffers, and similarly, using serial commands to query and change configurations of the WiFi module.

ESP8266 ESP-01 Serial WIFI Transceiver Module is a cheap and easy way to connect to internet via WIFI to any microcontroller platforms like Arduino. You can use AT commands to connect to WiFi networks and open TCP/IP connections (without need to have TCP/IP stack running in microcontroller).

The module(ESP-01) can work with AT command when used with Arduino, USB to TTL adaptor (FTDI USB module is recommended). Additional power supply might be needed to power up the board.With GCC toochain and SDK availability opportunities with ESP8266 as a IOT device is endless.
