EasyESP-1 is a rapid prototyping and development board for the low-cost, WiFi-enabled ESP8266 microcontroller, specially designed for beginners. With an onboard USB-to-Serial converter pre-installed, EasyESP-1 does not require any additional hardware to download your application firmware to the ESP8266 chip. The ESP module used in this development board is ESP-12E. All the I/O pins are broken out to 0.1” female headers for easy access, as well as to standard Grove/Crowtail connectors for connecting Grove/Crowtail sensors and other compatible modules. The 180-point breadboard further facilitates experimenting and testing of external circuits connected to the ESP8266 peripherals.
