Keyestudio ESP8266 WI-FI Development Board with USB Cable
For Arduino-Based on ESP8266-12FWIFI /Support RTOS
The keyestudio ESP8266 WiFi development board is based on the ESP8266-12WIFI module developed by Ai-Thinker. The ESP8266 processor integrated the industry-leading Tensilica L106 ultra-low power 32-bit micro MCU in a smaller package with 16-bit Lite mode. The main clock frequency supports 80 MHz and 160 MHz.
It supports RTOS integrated with WiFi MAC/BB/RF/PA/LNA onboard and comes with a curved on-board antenna. This development boars is a standalone network controller which can add networking function to those existing devices.
Ports: 11 I/O (4 of which can be used as PWM output)
