SparkFun Qwiic Shield Arduino Compatible 4 ports 3.3V engineering development tool

SKU CH-DAH4-K9S7E

An easy-to-assemble shield that adds four Qwiic ports and a large prototyping area to Arduino boards, converting 5V to 3.3V for I2C devices

  • Product typeEngineering Development Tools
  • Add Qwiic sensors to Arduino with four built-in ports
  • Prototype custom circuits on the large integrated breadboard area
  • Organise wiring neatly using the 3-by-1 prototyping rails
  • On-board level shifting converts 5 V logic to 3.3 V for Qwiic devices
  • Daisy-chain multiple I2C sensors on the same bus for expanded sensing

Arduino Qwiic Integration Shield

This shield adds four Qwiic ports to an Arduino board, converting the 5 V supply to 3.3 V for compatible I2C devices. A large prototyping area and 3-by-1 rails give space for custom circuitry alongside the daisy-chain connectors. Four mounting holes allow a small sensor board to be secured on top of the shield. The kit arrives unassembled for straightforward soldering.

Upgrade from Flying-lead I2C Wiring

Replacing loose jumper wires with keyed Qwiic cables removes mis-connection risk and speeds up sensor swaps. The jump is worth it when a project grows beyond one or two I2C modules and a tidy, expandable bus becomes necessary. On-board voltage translation protects 3.3 V peripherals from the Arduino’s 5 V logic without extra level-shifter boards.

Makers Building Multi-sensor Arduino Projects

Suits developers who want a clean, solderable base for stacking several Qwiic sensors on a single I2C bus. Builders needing a ready-made, zero-soldering HAT or a shield with isolated buses for address conflicts should look at other form factors. Projects requiring more than four simultaneous Qwiic drops will need an additional hub or multiplexer.

Questions about this item

What Arduino boards does this shield fit?

The shield uses the standard Arduino Uno footprint so it fits Uno and compatible boards that share the same pin spacing.

How do I connect a Qwiic sensor to the shield?

Plug the sensor's JST cable into any of the four Qwiic ports; all ports share the same I2C bus so address conflicts are the only thing to watch.

What voltage do the Qwiic ports supply?

On-board circuitry converts the Arduino's 5 V supply to the 3.3 V required by Qwiic devices.
