{"title":"SparkFun ESP8266 Thing","handle":"sparkfun-esp8266-thing","url":"/products/sparkfun-esp8266-thing","description":"The SparkFun ESP8266 Thing is a breakout and development board for the ESP8266 WiFi SoC — a popular platform for IoT and WiFi-connected projects. All module pins are broken out to breadboard-compatible rows, and on-board power management includes a LiPo charger, 3.3V regulator, and power switch.\n\nProgram it through the Arduino IDE with the ESP8266 Arduino add-on, or use any other ESP8266-compatible toolchain. A 3.3V FTDI Basic (or compatible serial converter with DTR line) is required for programming.\n\nKey Features\n\n\nESP8266 WiFi SoC – Built-in WiFi for IoT connectivity\n\nLiPo Battery Support – On-board charger and JST connector\n\n3.3V Regulator – Safe, regulated power to the ESP8266\n\nBreadboard Compatible – Pins broken out to two parallel rows\n\nArduino IDE Compatible – Program using the ESP8266 Arduino add-on\n\nPower Switch – On/off control with LED indicators for power, charge, and status\n\n\nSpecifications\n\n\nMCU: ESP8266\n\nOperating Voltage: 3.3V (max 3.6V)\n\nI/O Voltage: 3.3V (level shifting required for 5V signals)\n\nPower Input: USB or LiPo battery\n\nProgramming: Via 3.3V FTDI serial converter (DTR line required)\n\n\nIdeal For\n\nIoT and connected device projects\nWiFi-enabled sensor nodes\nBattery-powered wireless applications\nLearning ESP8266 development\n\n\n\nWarning: The ESP8266 operates at 3.3V. Do not apply 5V signals directly to the I/O pins — use a level shifter for 5V logic.\n\n\nPackage Contents\n\n1× SparkFun ESP8266 Thing\n\n\nResources\n\nESP8266 Thing Hookup Guide\n","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":11971,"title":"Default Title","sku":"SF-WRL-13231","price":40.37,"on_sale":false,"in_stock":true,"available_quantity":47,"option1":"Default Title"}]}
