This article covers SparkFun Qwiic to Grove アダプターケーブル (100mm).

Overview

The SparkFun Qwiic to Grove Adapter Cable (100mm) is a ready-to-use I2C interconnect cable designed to bridge SparkFun's Qwiic connector system (4-pin JST) with Seeed Studio's Grove I2C ecosystem. Measuring just 100mm in length, this compact cable allows you to connect Qwiic sensors and modules to Grove-compatible boards without soldering or additional wiring. It comes fully assembled and tested, making it an ideal solution for rapid prototyping and hobbyist electronics projects where different I2C connector standards need to be linked.

Key Features

4-pin JST connector on the Qwiic side and Grove-compatible connector on the other, enabling direct connection between Qwiic and Grove I2C devices. This eliminates the need for custom wiring or adapters when mixing components from both ecosystems. Cable length of 100mm keeps wiring tidy and minimizes clutter in compact builds or breadboard setups. Short cable runs also reduce signal interference in I2C communication. Pre-assembled and tested out of the box – no soldering, crimping, or configuration required. Simply plug and play. Although labeled as USB 2.0 cable type, it carries the standard I2C signals (SDA, SCL, VCC, GND) compatible with both Qwiic and Grove pinouts. Ensure your devices use the same pin mapping. * Manufactured by SparkFun, a trusted brand in the maker community, ensuring consistent quality and reliable performance.

Connectivity & Compatibility

This adapter cable connects SparkFun Qwiic boards (using 4-pin JST, 1.0mm pitch) to Seeed Studio Grove I2C devices (4-pin, 2.0mm pitch). It is specifically designed for I2C communication; do not use it with analog or digital Grove modules that require different pin assignments. Always verify that the VCC, GND, SDA, and SCL pins match between your Qwiic and Grove devices. The cable works with any I2C-based sensor, display, or module that follows the standard Qwiic or Grove I2C pinout.

Product Info

The SparkFun Qwiic to Grove Adapter Cable (100mm) is available through major online retailers like . Pricing typically ranges from a few hundred yen, making it an affordable accessory. It comes as a single cable, fully assembled and tested. SparkFun's standard warranty applies. No additional accessories are included.

Best Use Cases

Makers and developers who need to combine Qwiic sensors (e.g., SparkFun environmental sensors) with Grove-based microcontrollers or shields (e.g., Seeed Studio Arduino Grove shields). This cable provides a seamless bridge. Beginners who want to avoid soldering and prefer plug-and-play connections. The pre-assembled cable allows immediate experimentation. * Space-constrained projects where long cables would cause clutter. The 100mm length is perfect for compact enclosures or breadboard layouts.
