Ai Thinker NodeMCU-ESP8266 is an open-source firmware and development kit that helps you to prototype or build IoT products. It includes firmware that runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which is based on the ESP-12 module. The firmware uses the Lua scripting language. It is based on the eLua project and built on the Espressif Non-OS SDK for ESP8266.SpecificationsWIFI moduleESP-12SProcessorESP8266ChipCH340 ChipBuilt-in Flash32MbitAntennaOnboard PCB antennaPeripheral interfaceUART/SPI/I2C/SDIO/GPIO/ADC/PWMWiFi protocolIEEE 802.11 b/g/nFrequency range2.4G ~ 2.5G (2400M ~ 2483.5M)WIFI modeStation / SoftAP / SoftAP StationPower supply5VLogic level3.3VDimensions (mm)48.3 x 25.5 x 11.7Weight (g)7Shipment Weight0.01 kgFeatures:WIFI module: ESP-12SProcessor: ESP8266CP2102 ChipBuilt-in Flash: 32MbitAntenna: Onboard PCB antennaPeripheral interface: UART/SPI/I2C/SDIO/GPIO/ADC/PWMWiFi protocol: IEEE 802.11 b/g/nFrequency range: 2.4G ~ 2.5G (2400M ~ 2483.5M)WIFI mode: Station / SoftAP / SoftAP StationPower supply: 5VLogic level: 3.3VPackage includes:1 x Ai Thinker NodeMCU-ESP8266 Development Board
