Qwiic Shield for Arduino
Note: The shield includes R3 Arduino headers, but they are not pre-soldered onto the board, so
some assembly will be required when putting the shield together. The image below shows the shield
after the header has been soldered to the PCB to.
The Qwiic Shields have 4x Qwiic connect ports, all on the same I
C bus. Logic level converters are

included for the Qwiic connect port's SDA and SCL lines so you do not have to worry about using
the Qwiic system with 5V (or 3.3V) devices.
In addition to this, a large prototyping area is included. As shown in the image below, the Qwiic
shield for Arduino has a few neat features such as a few 3-by-1 rails to help with prototyping.

- Page 2 There are also buses for ground, 5V and 3.3V on the shield for Arduino outlined below. The headers also allow for every pin on the microcontroller of your choice to still be accessed through the female headers.
- Page 3 PCB to. The Qwiic shield for the Particle Photon also includes 4x Qwiic connect ports, a prototyping area, and buses for 3.3V and ground. However, they are much smaller. The Photon is a 3.3V system and assumes that you are using 3.3V devices so logic level conversion is not included in the design.

Hardware Assembly To get started with your Qwiic shield, all you’ll need to do is solder on headers. For a detailed description of how to do this with Arduino shields, simply check out our Arduino shield tutorial. It’ll get you started with attaching those headers to your shield properly. These tips are also useful when installing the headers for the Qwiic shield for Photon. - Page 5 Qwiic HAT for Raspberry Pi The Qwiic HAT has 4 Qwiic connect ports, all on the same I C bus. In addition to this, some of the pins on the Raspberry Pi are broken out for the user.
- Page 6 Hardware Assembly To get started with your Qwiic HAT, simply plug it into the headers on the Raspberry Pi, make sure that the “USB” arrow on the HAT is pointing towards the USB on the Raspberry Pi. Once the HAT is plugged in, you can start plugging in any Qwiic enabled sensors you might have.
- Page 7 I2C on Raspberry Pi - OS and Library Install If you’re starting from scratch, with a blank microSD card, you’ll want to install Raspbian. If you’ve already got a working Raspbian system, skip ahead to step 3. image. As of this writing, it’s at version 2.4.4. 1.
- Page 8 Utilities There is a set of command-line utility programs that can help get an I2C interface working. You can get them with the apt package manager. COPY CODEsudo apt-get install -y i2c-tools In particular, the program will probe all the addresses on a bus, and report whether any i2cdetect devices are present.
- Page 9 5V device and you are not using a stackable breakout board with a logic level converter (such as the Qwiic Shield for Arduino), you’ll need to grab a logic level converter to boost your signals up to 5V. Also, be aware that all Qwiic devices have pull-up resistors on the I C lines.
- Page 10 Hardware Assembly There are several different ways to connect your I C device to the Qwiic adapter. The simplest and probably cleanest method would be to use headers. This also allows the adapter to be reattached to C device in the future. I’ve found that I enjoy the look of the 90 degree male headers on a different I the Qwiic Adapter, combined with a 90-degree bend in the legs on the female headers I C device.
