The development board has an ESP-12E module with an ESP8266 chip with a Tensilica Xtensa® 32-bit LX106 RISC CPU that supports RTOS and runs at 80 to 160 MHz configurable clock frequency. There's also 128 KB of RAM and 4MB of Flash memory (for application and data storage), which is more than adequate to handle the enormous strings that create web pages, JSON/XML data, and everything else we want in IoT devices these days.
- Built-in Micro-USB, with flash and reset switches, easy to program
- Wireless 802.11 supported, direct download no need to reset
- Arduino compatible works great with the latest Arduino IDE/Mongoose IoT/Micro python
- WiFi at 2.4GHz, support WPA / WPA2 security mode
- Supports GPIO, PWM, I2C, SPI, UART and ADC.
