ACROBOTIC ESP8266 ESP-12E Development Board with USB-to-Serial Onboard

Regular price $9.95

Get started with the ESP8266 using this convenient development board for this widely popular, internet-capable chip!

As you may have heard, the ESP8266 Serial-to-WiFi adapter created by Espressif has seen a wide adoption as a cost-effective solution for IoT and WiFi-capable devices. This tiny-sized System On a Chip (SoC) includes an 80 MHz microcontroller with a full WiFi front-end (both as client and access point) as well as a full TCP/IP stack with DNS.

Because the ESP8266 comes only in a tiny surface-mount package (QFN-32), a few different vendors have developed a series of modules named ESP-NN where NN are numbers ranging from 01 to 13. Save for the first module, the ESP-01, these modules are also intended to be mounted on a PCB via castellated pins. Moreover, because the ESP8266 itself doesn't have a native USB interface, we need to use an external USB to Serial adapter to develop code using this module.

Thanks to this fantastic development board, everything needed to program the ESP-12E comes nicely packaged on a single board.
