What is the Grove Ecosystem?
Grove is a modular, standardized connector prototyping system. Compared to systems using jumpers or solder, Grove's modular building-block approach makes assembling real electronics easy. The Grove system consists of a base unit and various modules with standardized connectors. These were originally called "stems" and "twigs", but the names have been phased out.
The Base unit, generally a microprocessor, allows for easy connection of any input or output from the Grove modules. Each Grove module typically addresses a single function, such as a simple button or a more complex heart rate sensor. You don't need a Base unit to connect to others Grove modules. You can use a cable (Grove to Pin Header Converter) to run from the pins on the Raspberry Pi or Arduino to the Grove connectors.
What is in the Grove Ecosystem?
The Grove ecosystem provides a convenient and user-friendly approach to prototyping and building electronic systems. Its modular nature, standardized connectors, and wide range of modules make it easy for both beginners and experienced makers to assemble and experiment with real electronics quickly.
Grove Sensors
The Grove ecosystem offers a wide range of sensors that can be easily integrated into your electronics projects. These sensors are designed to address specific functions and can provide various types of input data.
Grove Network Modules
The Grove system also includes network modules that enable communication and connectivity in your projects. These modules allow you to connect your electronics to different networks, such as Wi-Fi, Bluetooth, LoRa, NFC, or other Standard Protocol.
With Grove network modules, you can easily add wireless capabilities to your projects, enabling data transmission, remote control, or interaction with other devices and the internet.
Grove Accessories
In addition to sensors and network modules, the Grove ecosystem offers a variety of accessories that complement and enhance your electronics projects. These accessories include components such as LCD displays, LED matrices, motor drivers, relay modules, and more.
The Boards supported by the Grove interface
The Grove interface is designed to be compatible with a wide range of development boards and microcontrollers.

The Kits come with the Grove Modules and Courses
Arduino Board-based
Grove Beginner Kit for Arduino is one of the best Arduino Beginner Kit for beginners. It includes one Arduino compatible Board with 10 additional Arduino sensors and an all-in-one-piece PCB design. All the modules have been connected to the Seeeduino through the PCB stamp holes so Grove cables are not needed for connection. However, you can also take the modules out and use Grove cables to connect the modules. You can build any Arduino project you like with this Grove Beginner Kit For Arduino!

You can check it out on the Bazaar Purchase Page. We have launched Grove - I2C Hub (6 Port) for this function.
Grove - Branch Cable for Servo
Grove Branch Cable for Servos is used to connect one or two servos to a project, with power and ground shared between the connectors and individual PWM signals for each servo connected to the Arduino's PWM-capable pins. The cable's four-pin keyed connector is typically connected to a Grove Shield digital socket, and the wire color (yellow or white) indicates the corresponding digital pin for the servo input.
You can check it out on the Bazaar Purchase Page.
Grove & Qwiic/STEMMA QT Interface to Male/Female Jumper Cables
This cable helps you to connect multiple Grove, Qwiic, and STEMMA QT modules to your development boards using a single cable.
You can connect one Grove Module and one Qwiic Module or STEMMA QT Module to Seeeduino Lotus or Arduino UNO.

Interface of Grove modules
You may notice that Grove cables come in 4 different colours.
- Pin 1 - Yellow (for example, SCL on I2C Grove Connectors)
- Pin 2 - White (for example, SDA on I2C Grove Connectors)
- Pin 3 - Red - VCC on all Grove Connectors
- Pin 4 - Black - GND on all Grove Connectors
There're mainly 4 type of Interface of Grove modules.
Grove Digital
A digital Grove connector consists of the standard four lines coming into the Grove plug. The two signal lines are generically called D0 and D1. Most modules only use D0, but some do (like the LED Bar Grove display) use both. Often base units will have the first connector called D0 and the second called D1 and they will be wired D0/D1 and then D1/D2, etc.
Examples of Grove Digital modules are: Switch Modules, the Fan Module, and the LED Module. In Figure 8, you can see what the Grove connector looks like on the schematic for the LED Grove module. They can range from simple to very complex.
| pin | Function | Note |
|---|---|---|
| pin1 | Dn | Primary Digital Input/Output |
| pin2 | Dn+1 | Secondary Digital Input/Output |
| pin3 | VCC | Power for Grove Module, 5V/3.3V |
| pin4 | GND | Ground |
Grove Analog
A Grove Analog connector consists of the standard four lines coming into the Grove plug. The two signal lines are generically called A0 and A1. Most modules only use A0. Often base units will have the first connector called A0 and the second called A1 and they will be wired A0/A1 and then A1/A2, etc.
| pin | Function | Note |
|---|---|---|
| pin1 | An | Primary Analog Input |
| pin2 | An+1 | Secondary Analog Input |
| pin3 | VCC | Power for Grove Module, 5V/3.3V |
| pin4 | GND | Ground |
Grove UART
The Grove UART module is a specialized version of a Grove Digital Module. It uses both Pin 1 and Pin 2 for the serial input and transmit. The Grove UART plug is labeled from the base unit point of view. In other words, Pin 1 is the RX line (which the base unit uses to receive data, so it is an input) where Pin 2 is the TX line (which the base unit uses to transmit data to the Grove module).
| pin | Function | Note |
|---|---|---|
| pin1 | RX | Serial Receive |
| pin2 | TX | Serial Transmit |
| pin3 | VCC | Power for Grove Module, 5V/3.3V |
| pin4 | GND | Ground |
Grove I2C
Those long term readers of this blog know that our favourite devices are I2C sensors. There are many types of I2C Grove sensors available. Most are 5V/3.3V devices, but there are a few that are only 3.3V or 5.0V. You need to check the specifications.
The Grove I2C connector has the standard layout. Pin 1 is the SCL signal and Pin 2 is the SDA signal. Power and Ground are the same as the other connectors. This is another special version of the Grove Digital Connector. In fact, often the I2C bus on a controller (like the ESP8266, Raspberry Pi and the Arduino) just uses Digital I/O pins to implement the I2C bus. The pins on the Raspberry Pi and Arduino are special with hardware support for the I2C bus.
| pin | Function | Note |
|---|---|---|
| pin1 | SCL | I2C Clock |
| pin2 | SDA | I2C Data |
| pin3 | VCC | Power for Grove Module, 5V/3.3V |
| pin4 | GND | Ground |
