ESP8266 ESP-01E Remote Serial WiFi Transceiver with 1MB Flash

ESP8266 ESP-01E Remote Serial WiFi Transceiver is just like ESP-01. Well, an upgraded version we could say. Like its predecessor, ESP-01E can communicate with AT commands, or be flashed with Lua or even be used with an Arduino. However, the flash memory size has been doubled from 512 KB to 1 MB.

With exact same dimensions of ESP-01, ESP-01E is tiny (25mm x 15mm) and fits in compact space, with simple pin connections (standard 2×4 pin headers). Similer to the previous version, communication with ESP-01E can be done over serial TX/RX pins using AT commands. AT commands help with querying and changing the configurations of WiFi module.

Thus it would need only two wires (TX/RX) to communicate between a micro-controller and WiFi, but more importantly, it offloads WiFi-related tasks to the module, allowing the microcontroller code to be very light-weighted. Its powerful on-board processing and storage capabilities which allows the module to be integrated with sensors and other application specific devices through its GPIOs.

ESP-01E is also addressable over SPI and UART, making this an exceptionally easy choice for anyone to build an Internet of Things thing. You can use AT commands to connect to WiFi networks and open TCP connections without need to have TCP/IP stack running in your own microcontroller. ESP8266 ESP-01E Remote Serial WiFi Transceiver works effortlessly with platforms like Arduino
