The Adafruit QT Py ecosystem is so tiny yet powerful, we wanted to share them, one each day. Today is the Adafruit QT Py RP2040!
This diminutive dev board comes with one of our new favorite chip, the RP2040. It’s been made famous in the new Raspberry Pi Pico and our Feather RP2040 and ItsyBitsy RP2040, but what if we wanted something really smol?
A new chip means a new QT Py, and the Raspberry Pi RP2040 is no exception. When we saw this chip we thought “this chip is going to be awesome when we give it the cuuutie QT Py Treatment”, and so we did! This QT Py features the RP2040, and all niceties you know and love about the original QT Py
Plug-and-play STEMMA QT
The star of the QT Py is our favorite connector – the STEMMA QT, a chainable I2C port that can be used with any of our STEMMA QT sensors and accessories. Having this connector means you don’t need to do any soldering to get started.
What can you pop into the QT port? How about OLEDs! Inertial Measurment Units! Sensors a-plenty. All plug-and-play thanks to the innovative chainable design: SparkFun Qwiic-compatible STEMMA QT connectors for the I2C bus so you don’t even need to solder. Just plug in a compatible cable and attach it to your MCU of choice, and you’re ready to load up some software and measure some light.
Use any SparkFun Qwiic boards! Seeed Grove I2C boards will also work with this adapter cable.
Software Support
There is great C/C++ support, unofficial (but really good) Arduino support, an official MicroPython port, and a CircuitPython port! We of course recommend CircuitPython because we think it’s the easiest way to get started and it has support with most of our drivers, displays, sensors, and more, supported out of the box so you can follow along with our CircuitPython projects and tutorials.
USE
