It integrates GPIO, PWM, I2C, 1-Wire, and ADC on a single breadboard-friendly board, and can be programmed with the Arduino IDE or NodeMCU Lua firmware.\n\nThe R2 version improves on the original with a CP2102 USB chip (replacing CH341) for better driver compatibility, higher current support, and a slimmer form factor that fits directly on a standard breadboard.\n\nKey Features\n\n\nESP-12E Wi-Fi Module – ESP8266 with 6 extra GPIOs compared to the ESP-12\n\nCP2102 USB-to-UART – Reliable USB interface, no CH341 driver needed\n\nArduino IDE Compatible – Program directly using the Arduino ecosystem\n\nNodeMCU Lua Firmware – Pre-flashed, ready to use out of the box\n\nBreadboard Friendly – Slim design fits standard breadboards\n\nMicro USB Power – 5 V power, programming, and debugging via micro USB\n\nGPIO Access – 2× 15-pin headers (2.54 mm) with GPIO, SPI, UART, ADC, and power pins\n\nReset and Flash Buttons – On-board buttons for easy firmware flashing\n\n\nSpecifications\n\n\nChip – ESP8266 (ESP-12E module)\n\nUSB Bridge – CP2102\n\nPower – 5 V via micro USB\n\nDimensions – 49 × 24.5 × 13 mm\n\n\n\nTip: Use a high-quality USB cable capable of supplying sufficient current. Low-quality cables may prevent the board from being recognised by your computer.\n\n\nIdeal For\n\nIoT and Wi-Fi connected projects\nHome automation and sensor networks\nRapid prototyping with Arduino IDE or Lua\nLearning ESP8266 development\n\n\nResources\n\nNodeMCU DevKit – Hardware Schematics & PCB Layout (GitHub)\nNodeMCU Firmware Source Code (GitHub)\nNodeMCU Flasher – Windows Firmware Tool (GitHub)\nFlashing NodeMCU Firmware on Linux (Guide)\nCP210x USB-to-UART Bridge Drivers (Silicon Labs)\n","vendor":"Elecrow","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":3696,"title":"Default Title","sku":"EC-DPO02102N","price":9.51,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":109,"option1":"Default Title"}]}
