It breaks out microcontroller pins to clearly labeled headers and provides both 3.3 V and 5 V power rails, making it easy to mix sensors that require different logic and supply voltages in one project.\u003c\/p\u003e\n\u003cp\u003eIntended for prototyping and education, this board helps reduce wiring clutter and speeds up development of sensor‑rich projects such as data loggers, smart‑home systems, and robotics. Plug in sensors with jumper wires or compatible cables, route signals through the expansion headers, and focus on code instead of breadboard chaos.\u003c\/p\u003e\n\u003ch2\u003eIdeal Uses\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSensor‑rich prototypes  such as weather stations, data loggers, and IoT nodes.\u003c\/li\u003e\n\u003cli\u003eEducational projects and classroom labs  where students frequently plug and unplug different sensors.\u003c\/li\u003e\n\u003cli\u003eRobotics and smart‑car platforms  needing clean breakout of multiple sensor connections.\u003c\/li\u003e\n\u003cli\u003eRapid prototyping and testing  of new sensors, modules, and interface circuits without constant rewiring.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eWorks with  3.3 V and 5 V microcontrollers, including typical Arduino boards, ESP32\/ESP8266 boards, and many STM32 or similar development boards (using jumper wires as needed).\u003c\/li\u003e\n\u003cli\u003eProvides  3.3 V and 5 V power rails  so you can power sensors of different voltage requirements from the same expansion board (within your regulator’s capacity).\u003c\/li\u003e\n\u003cli\u003eDesigned as a  general‑purpose expansion: suitable for digital and analog sensors, I²C\/SPI devices, and other small modules that connect via pin headers or dupont wires.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMultiple sensor headers  with clearly labeled pins (e.g., VCC, GND, signal), simplifying plug‑and‑play sensor connections.\u003c\/li\u003e\n\u003cli\u003eDual‑voltage support  with 3.3 V and 5 V power rails available on the board for mixed‑voltage sensor setups.\u003c\/li\u003e\n\u003cli\u003eCentral  power distribution  with decoupling capacitors to help stabilize sensor power lines.\u003c\/li\u003e\n\u003cli\u003eCompact PCB with mounting holes and standard pin spacing, suitable for mounting inside enclosures or on robot chassis.\u003c\/li\u003e\n\u003cli\u003eIdeal as a  hub board  for organizing sensor wiring in larger projects.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTechnical Specs (Typical, Board‑Dependent)\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eExact specifications depend on the specific Sensor Expansion Board V2 design:\u003c\/li\u003e\n\u003cli\u003eSupported Supply Voltages: typically accepts  5 V input, with on‑board regulation to  3.3 V  for lower‑voltage sensors.\u003c\/li\u003e\n\u003cli\u003ePower Rails: separate  3.3 V,  5 V, and  GND  rails routed to sensor headers.\u003c\/li\u003e\n\u003cli\u003eHeaders: multiple 3‑pin or 4‑pin sensor connectors (e.g., VCC\/GND\/SIG, or VCC\/GND\/SDA\/SCL for I²C‑style connections).\u003c\/li\u003e\n\u003cli\u003eForm Factor: small to medium‑sized PCB designed for use with dupont wires or direct header connections.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhat’s Included\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1 × Sensor Expansion Board V2 – 3.3 V \/ 5 V Compatible Development Extension Module\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSafety Note\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eEnsure the total  current draw of all connected sensors  stays within the limits of your 3.3 V and 5 V regulators; overloading can cause voltage drops or damage.\u003c\/li\u003e\n\u003cli\u003eDouble‑check  voltage selection and pin labels  before plugging in sensors; connecting a 3.3 V‑only sensor to 5 V can damage it.\u003c\/li\u003e\n\u003cli\u003eKeep wiring organized and strain‑relieved, especially in mobile robots, to prevent intermittent connections or shorts.\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"sugar","offers":[{"title":"Default Title","offer_id":44922464993415,"sku":null,"price":19.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0736\/7763\/5719\/files\/SensorExpansionBoardV2_3.3V5VCompatibleDevelopmentExtensiontop.jpg?v=1781874918","url":"https:\/\/sugarstore.dev\/products\/sensor-expansion-board-v2-3-3-v-5-v-compatible-development-extension-module","provider":"sugar","version":"1.0","type":"link"}
