The SparkFun Qwiic SHIM for Raspberry Pi is a small, easily removable breakout that easily adds a Qwiic connector to your Raspberry Pi. The SHIM design allows you to plug directly to the Pi's I2C bus with no soldering required and the thin PCB design allows for it to be sandwiched on your Pi GPIO with other HATs! The Qwiic SHIM works great when you do not need the full capabilities of the Qwiic pHAT for Raspberry Pi or if you want to add a Qwiic connector to your Pi but do not have room for yet another HAT.
The Qwiic SHIM uses a unique friction-based connector that wedges itself onto the GPIO header for a secure, solderless connection. As you would expect, it has a single Qwiic connector that connects to your Pi's I2C bus (SDA, SCL, 5V and Ground). The SHIM also has a 3.3V regulator so it will work with all Qwiic devices. Even better, the SparkFun Qwiic SHIM will also work with the NVIDIA Jetson Nano Developer Kit!
The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
Jargon buster
Plain-language definitions for the technical terms used above.
- 3.3V regulator
- A 3.3V regulator is a power circuit that provides a steady 3.3 volts for parts that need that supply voltage. On a breakout board, it can let the sensor run safely even when the connected microcontroller or power source uses a higher voltage.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- NVIDIA Jetson Nano
- The NVIDIA Jetson Nano is a compact NVIDIA computing module used for camera, robotics and machine-learning projects at the edge. A compatible carrier board can host the module, though the module itself is usually sold separately.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- pHAT
- A smaller add-on board format for Raspberry Pi, similar in idea to a HAT but usually not full-sized. It matters because pHAT compatibility can affect how neatly a board stacks or fits into a Raspberry Pi project.
- Qwiic
- Qwiic is a plug-in connector system for I2C devices that uses small 4-pin cables, so you can connect compatible sensors without soldering. It matters because your controller or adapter also needs Qwiic, or you will need a cable or breakout to wire it up.
