Connect your next Arduino project with an adorable microcontroller at a very affordable price! This Wi-Fi module is part of ESP8266 series which is a high-performance wireless System On a Chip (SOC). It is designed for minimal space requirement and offers a complete and standalone Wi-Fi networking solution at the lowest possible cost. It can be used to host the application or to offload Wi-Fi networking functions from another application processor. It has an onboard PCB antenna and 9 GPIOs + ADC.
ESP-12F is an upgrade based on ESP-12E and has 22 pin counts. The revised antenna design increased communication distance by 30%-50% 16 pin counts. It is also FCC, CE and RoHS approved module is fully compatible with previous versions of ESP-12 series.
