Geekcreit® ESP-F ESP8266 Remote Serial Port WiFi IoT Module Nodemcu LUA RC Authenticity

Introduction ESP8266 F is an enhanced version of ESP8266 12E improve the peripheral circuit the four laminates plate process enhanced impedance matching the signal output is better it is stable with anti jamming ability PCB antennaafter professional laboratory testing perfect matching after ROHS certification have been greatly improved The enhanced version is fully compatible with the firmware before the ESP 12 based on the SPI and the new six IO port mouth extraction development is more convenient application is more widely ESP8266 F built cloud services that you can use three commands into the global remote control function ESP F ground breaking design the new four layer board design the new revision antenna RF performance optimization increased by 30 50 Communication distance compared to the ESP 12E Semi hole chip technology the whole IO leads with metal shielding shell has passed FCCCERoHS certification built board PCB antenna 4M bytes Flash Package included 1 x ESP F ESP8266 Remote Serial Port WiFi IoT Module
