Description:

This keyestudio ESP8266 WI-FI development board is based on the ESP8266-12FWIFI module developed by Ai-Thinker.

The processor ESP8266 integrates the industry-leading Tensilica L106 ultra-low-power 32-bit micro MCU in a smaller package, with 16-bit Lite mode. The main frequency supports 80MHz and 160 MHz.

It supports RTOS, integrated with Wi-Fi MAC/BB/RF/PA/LNA. Onboard comes with curved antenna.

This development board is a standalone network controller, which can add networking function to those existing devices.

When using, power the board and upload the program via a Micro USB port, and the current supply should be 2A.
