3Pcs ESP8266 1Cable NodeMCU CH340 ESP-12E WiFi Development Board for Arduino IDE

About this deal

This pack contains three NodeMCU ESP8266 ESP-12E Wi-Fi development boards along with a USB cable. Based on the ESP8266 Wi-Fi transceiver module and the CH340 USB converter chip, each board is a compact, open-source development and prototyping board well suited to IoT applications. The ESP-12E module houses a Tensilica Xtensa 32-bit LX106 RISC microprocessor that supports RTOS and runs at an adjustable 80 MHz to 160 MHz clock frequency, paired with 128 KB RAM and 4 MB of flash memory. The Wi-Fi module is compatible with the 802.11 b/g/n standard at 2.4 GHz and features an integrated TCP/IP stack, GPIO, PWM, I2C, SPI, and a PCB antenna. Connection to a PC is via a micro USB port, which handles power, programming, and debugging. The ESP8266 can be flashed and programmed using the Arduino IDE, and a large number of libraries are available thanks to its sizeable open-source developer community. Buying three boards at once makes this a practical choice for hobbyists, students, or anyone building multiple IoT prototypes simultaneously.
