Grove Base Shield V2.0 for Arduino-The Easiest Way to Connect Grove Sensors to Arduino

DESCRIPTION Arduino Uno is one of the most widely used Arduino boards, but a project with more than a few sensors quickly turns into a mess of breadboards and jumper wires. Grove Base Shield V2.0 solves this by breaking out every pin on an Arduino-Uno-shaped board into 16 standardized Grove connectors, so Grove modules can be connected directly without a breadboard or soldering. The shield's pinout is the same as Arduino Uno R3, and an onboard 5V/3.3V power switch keeps it compatible with both 5V boards (e.g. Arduino Uno, Mega) and 3.3V boards (e.g. Arduino Due). No More Jumper Wires: Grove's keyed connectors replace tangled breadboard wiring. Save Time on Setup: modules plug in directly, with no wiring diagrams to follow. Learn More Easily: a clear, physical layout makes it easier to see how a circuit is wired. Easy to Expand Your Projects: add more Grove modules without redoing existing wiring. The Grove Base Shield V2 is designed to simplify Arduino prototyping by transforming standard GPIO headers into dedicated Grove interfaces. Instead of spending time on breadboards and jumper wires, you can connect Grove modules directly through Analog, Digital, UART, and I2C ports, making hardware development faster, cleaner, and significantly easier to manage. Built around the Grove plug-and-play ecosystem, the Base Shield V2 provides instant access to more than 300 Grove modules, including sensors, displays, actuators, communication modules, and AI peripherals. The onboard 5V/3.3V power switch allows the same shield to work seamlessly with both 5V and 3.3V Arduino-compatible boards, while its Uno R3-compatible layout ensures broad compatibility with Arduino Uno, Mega, Leonardo, Due, Zero, Seeeduino, and LinkIt ONE. Whether you're learning electronics, building STEM projects, or rapidly validating hardware prototypes, Grove Base Shield V2 lets you spend less time wiring and more time creating. Simplify your Arduino prototyping with the Grove Base Shield V2. Instead of spending time on breadboards and jumper wires, simply plug Grove modules directly into dedicated Analog, Digital, UART, or I2C ports and start building in minutes. Fully compatible with 300+ Grove modules, the shield makes it easy to prototype, learn, and expand projects while maintaining clean, reliable wiring. With support for both 5V and 3.3V development boards, plus broad compatibility across Arduino Uno, Mega, Leonardo, Due, Zero, Seeeduino, and LinkIt ONE, it's the fastest way to bring hardware ideas to life. FEATURES 16 On-board Grove Connectors: 4x Analog, 7x Digital, 1x UART, and 4x I2C ports for connecting Grove modules directly, without extra wiring. Grove Ecosystem Compatibility: instantly compatible with Seeed Studio's full lineup of 300+ Grove modules — sensors, actuators, displays, and communication modules. Switchable 5V/3.3V Power: an onboard toggle switch matches the shield's Vcc output to 5V boards (e.g. Arduino Uno, Mega) or 3.3V boards (e.g. Arduino Due). Same Pinout as Arduino Uno R3: compatible with Arduino Uno, Mega, Leonardo, Due, Zero, the Seeeduino family, and LinkIt ONE. Keyed Grove Connectors: four-pin connectors are polarity-protected, preventing reverse connections. Reset Button: resets the host Arduino board without removing the shield. ICSP Header Pass-through: keeps the host board's ICSP pins accessible for programming. Power Indicator LED: onboard green LED lights up when the shield is powered. Compact Stackable Form Factor: 69 x 53mm, designed to stack directly onto Uno-shaped boards.
