Yellow Board ESP8266 – WiFi module ESP-12E + Battery Holder

Board with the wifi ESP-12E module with connectors in the form of goldpin pins. Led out are 9 GPIO 1 analogue input and RX, TX, RESET, CH_PD pins, power supply and ground. Also on board are LEDs, photoresistor and the voltage regulator of 3.3 V. In addition, the chip has a holder that allows for the power supply using three AA batteries.
