Product information "Adafruit QT Py RP2040"

What a cute little chap! Or is it... a QT Py? This tiny development board is equipped with one of our new favourite chips, the RP2040. It was made famous in the new Raspberry Pi Pico and in our Feather RP2040 and ItsyBitsy RP2040, but what if we wanted something really small?

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 will be awesome if we give it the QT Py treatment," and we did! This QT Py features the RP2040 and all the conveniences you know and love from the original QT Py

PLUG-AND-PLAY STEMMA QT

The star of the QT Py is our favourite connector - the STEMMA QT, a daisy-chainable I2C connector that can be used with all of our STEMMA QT sensors and accessories. This connector means you don't need to do any soldering to get started.

What can you connect to the QT connector? How about OLEDs! Inertial measurement devices! Sensors galore. 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 have to solder. Just plug in a compatible cable and connect it to the MCU of your choice, and you're ready to load software and measure light.

Use all SparkFun Qwiic boards! Seeed Grove I2C boards also work with this adapter cable.

SOFTWARE SUPPORT

At the time of launch, there is no Arduino core support for the chip on this board. There is great C/C++ 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 because it supports most of our drivers, displays, sensors and more, right from the start, so you can follow our CircuitPython projects and tutorials.

QT PY RP2040 SPECIFICATIONS

pinout and shape are compatible with Seeed Xiao, with honeycomb-shaped pads so you can solder it to a board with a cutout to give the bottom components some clearance. As well as the QT connector, we've also added an RGB NeoPixel (with a controllable power pin to allow ultra-low power operation) and both boot mode and reset buttons (ideal for restarting your programme or accessing the bootloader). This QT Py comes with loose 0.1" leads that you can solder in for use on a breadboard.

The RP2040 has plenty of onboard RAM (264KB), but no inbuilt FLASH memory. Instead, this is provided by an external QSPI flash chip. There is 8MB on this board, which is shared between the running programme and the file memory used by MicroPython or CircuitPython. When using C/C++, the entire flash memory is available; when using Python, around 7 MB remains for code, files, images, fonts, etc.

Same size, form factor and pin assignment as our SAMD-based QT Py
USB Type-C connector
RP2040 32-bit Cortex M0+ dual-core with ~125 MHz at 3.3 V logic and power
264 KB RAM
8 MB SPI FLASH chip for storing files and CircuitPython/MicroPython code. No EEPROM
Native USB support by any operating system - can be used as a USB serial console, MIDI, keyboard/mouse HID and even as a small drive to store Python scripts.
Can be used with MicroPython or CircuitPython
Built-in RGB NeoPixel LED
13 GPIO pins (11 breakout pads and two QT pads):
- Four 12-bit ADCs (one more than the Pico)
- Two I2C ports (one on the QT connector, one on the breakout pads)
- SPI and UART peripherals on the standard QT Py positions,
- PWM outputs on each IO pin - for servos, LEDs, etc.
- There are 6 GPIO in sequential order for PIO compatibility
3.3V regulator with 600mA peak output
12 MHz crystal
Both reset button and bootloader select buttons for quick restarts (no unplugging and replugging to restart the code)
Really very small

ABOUT THE RP2040

Inside the RP2040 is a 'permanent ROM' USB UF2 bootloader. This means that if you want to program new firmware, you can hold down the BOOT button while connecting the device to USB (or pull the RUN/Reset pin to ground) and it will appear as a USB drive that you can drag the firmware to. People who use Adafruit products will find this very familiar - we use this technique on all of our native USB boards. Just note that you don't double-click Reset, but hold down BOOTSEL during boot to start the bootloader!

The RP2040 is a powerful chip that has the clock speed of our M4 (SAMD51) and two cores equivalent to our M0 (SAMD21). As it is an M0 chip, it does not have a floating point unit or DSP hardware support - so if you are doing something with extensive floating point calculations, this is done in software and is therefore not as fast as an M4. For many other computing tasks, you can get close to M4 speeds!

There are two I2C controllers, two SPI controllers and two UARTs for the peripherals, which are multiplexed via GPIO - the pin assignment shows which pins can be assigned in which way. There are 16 PWM channels, each pin has a channel to which it can be set (ditto in the pinout).

You will notice that there is no I2S peripheral, no SDIO and no camera, so what's the point? Well, instead of having specific hardware support for serial data-like peripherals like these, the RP2040 comes with the PIO state machine system, which provides a unique and powerful way to create custom hardware logic and data processing blocks that run standalone without taking up a CPU. For example, NeoPixels - we often bitbang the timing-specific protocol for these LEDs. For the RP2040, we use a PIO object instead, which reads in the data buffer and outputs the correct bitstream with perfect accuracy. The same applies to I2S audio inputs and outputs, LED matrix displays, 8-bit or SPI-based TFTs and even VGA! In MicroPython and CircuitPython, you can create PIO control commands to script the peripheral and load it at runtime. There are 2 PIO peripherals, each with 4 state machines.

Adafruit: The expert for open source hardware

For more than ten years, programmers and tinkerers have benefited from the expertise of the Adafruit brand. Whether for beginners or proven experts, Adafruit has the right hardware components ready for your next IoT project.

Light comes into the dark with Adafruit NeoPixel

One extremely popular product line from the company's broad portfolio is Adafruit NeoPixel. These nifty LED components come in a wide variety of designs and color temperatures. NeoPixel modules are available, for example, in the form of a practical stick with five intelligent LEDs in red, green and blue (RGB) or in white (W), as a shield with 40 eye-saving RGBW LEDs in which all pixels are individually addressable, and as a jewel with seven RGBW LEDs that can be controlled with 8-bit PWM per channel.

Especially popular is the Adafruit NeoPixel Ring with 16 ultra-bright, intelligent RGB LEDs including integrated drivers, which you only need a single microcontroller to control. The trick is that the Adafruit NeoPixel rings form a chain, so to speak: You couple the output pin of one with the input pin of the other.

With the Adafruit NeoPixel products you can realize a wide variety of projects - there are virtually no limits to your creativity. With the help of an Arduino, a jumper cable and the appropriate software, you can control a NeoPixel ring individually and light up the small LEDs as you wish - either individually or in a specific combination. This way, you can also create your own Vu meter with the versatile LED components. Practical: To make programming Adafruit NeoPixel easier, Adafruit provides an Arduino library as well as a Python library.

Adafruit Feather Boards: Powerful hardware in a compact format

With Adafruit Feather, the hardware specialist from the States also has various powerful development boards in its range, which are essentially equivalent to an Arduino in terms of function. All of these boards are equipped with similar features; among other things, the pin assignment is the same and there are also many parallels when it comes to the microcontrollers and the battery charging properties. In addition, you can also find Feather boards with special devices like Bluetooth, Wi-Fi and cellular network connectivity as well as boards with microSD slot in Adafruit's product range. The name "Feather" is no coincidence: The boards are also characterized by being particularly compact and, above all, lightweight.

The range of top-class product highlights is wide: The STM32F405 Feather, for example, is the fastest CircuitPython board from Adafruit with an outstanding 168 MHz and meets the highest demands. It is equipped with a STEMMA QT / Qwiic port at the end, which makes it easy to connect to I2C sensors. The Adafruit Feather nRF52840 Express, on the other hand, shines with Bluetooth Low Energy and can also be used with CircuitPython thanks to native USB support.

Another important part of Adafruit's portfolio are the FeatherWings. With these expansion modules, you can also include components such as a display or a motor driver in your IoT project. The FeatherWing Proto is a proven classic in Adafruit's portfolio. This is ideally suited as a prototyping add-on for all Feather boards. The Adafruit FeatherWing Wing Tripler Mini Kit, on the other hand, is ideal if you want to connect a Feather to two other FeatherWings at the same time.

With the Adafruit MIDI FeatherWing Kit you get a music capable FeatherWing, thanks to which you can equip your Feather with MIDI input and output jacks. And with the Adafruit FeatherWing OLED you can easily add a small OLED display to your Feather board - no soldering required.

Adafruit: What's behind the brand

As an expert in open-source hardware, Adafruit has long since established itself in the electronics industry. The company was founded in 2005 by Limor Fried. At the time, the talented and innovative electrical engineer was still a student at the renowned Massachusetts Institute of Technology (MIT). To this day, Fried is CEO of the electronics giant, which is now headquartered in New York. The company's name also goes back to its founder: Fried was once known on the World Wide Web by the nickname "Ladyada" - a tribute to the famous IT pioneer Ada Lovelace.

Adafruit says it is committed to getting more people excited about technology and science - and thanks to its first-class products, the hardware expert from the USA is sure to succeed!
