1*Adafruit QT Py RP2040 Development Board Compatible with Raspberry Pi Pico 4900

Description: Welcome to the Patkor store Adafruit QT Py RP2040 development board The small development board is equipped with the popular RP2040 microprocessor, also used in the Raspberry PI Pico board.Unlike the Raspberry PI Pico, the QT Py board features the STEMMA QT, a connectable I2C connector that can be used with all STEMMA QT sensors and accessories. oled, inertiometer and sensor - all plug and play, thanks to the innovative connectable design :SparkFun Qwicc compatible STEMMA QT connector for I2C bus, so you don't even have to weld! Simply plug in a compatible cable that connects to the MCU of your choice and you can load software, for example, to measure light. Pin compatible with Seeed Xiao. With honeycomb shaped pads, you can weld them to a flat circuit board. In addition, an RGB NeoPixel(with controllable power pins for ultra-low power use) and a reset button (perfect for restarting programs or entering boot loaders) have been added to the QT connector. While the RP2040 has plenty of RAM (264kb), it has no built-in flash memory. It is provided by QSPI and is 8 MB in size, with about 7 MB available for free in Python. It is similar in size, shape and stitch distribution to Seeed Xiao.USB Type C connectorRP2040 32-bit Cortex M0+, dual-core 125 MHz clock264 KB RAM8mb SPI Flash, no EEPROMLocal USB supported by any operating system - can be used in Arduino or CircuitPython as a serial USB console, MIDI, keyboard/mouse HID, or even as a small hard drive to store Python scripts.Can be used with MicroPython or CircuitPythonBuilt-in RGB NeoPixel LED13 GPIO pins (11 pins + 2 QT pads):4x 12-bit analog-to-Digital Converter (ADC)2 I2C ports (1 via QT port, 1 via pin)SPI and UARTPWM output on all I/O pins3.3V controller, peak power 600 mA12 MHz oscillatorStart the reset switch for project code or boot loader modeVery, very smallCurrently, the chip on the board does not support Arduino. Have a good C/C + + support (http://github.com/raspberrypi/pico-sdk), An official MicroPython port (http://github.com/raspberrypi/micropython) and a CircuitPython port (http://circuitpython.org/downloads)! The RP2040 includes a USB UF2 BOOT loader with permanent ROM, which means that if you want to program a new firmware, you can hold down the Boot key while connecting the board to your computer's USB port. The board will appear as a USB drive, and you can drag the firmware to it. If you have used the CircuitPython board before, you are probably familiar with this process. Note that instead of double-clicking RESET, hold down the BOOTSEL key during the boot process to invoke the boot loader! The RP2040 is a powerful chip with the same clock as our M4 (SAMD51) and the same two cores as our M0 (SAMD21). Because it is an M0 chip, there is no floating point unit or DSP hardware support. So if you want to calculate something with floating point math, it's done in software and therefore not as fast as M4. For many other computing tasks, the speed is similar to M4! For peripherals, there are 2 I2C controllers, 2 SPI controllers and 2 uart multiplexed via GPIO. Use pin assignment to check which pins can be set to which pins. There are 16 PWM channels, one for each pin that can be configured (also in pin assignment). You'll find no I2S port, no SDIO, and no camera connection. Why is that? Not specific Hardwareunterstutzung for having such Peripheriegerate usb port connection RP2040 along with PIO-Zustandsmaschinensystem provides a unique and powerful best option for restoring Hardwarelogik and Datenverarbeitungsblocke written to run independently without central obstruction. Take NeoPixel as an example - we often simulate the specific time protocol of these leds through software. For RP2040, we use a PIO object to read the data buffer and clock the correct bit stream with perfect precision. The same applies to I2S audio input or output, LED matrix display, 8 or SPI TFTs, even VGA (http://github.com/raspberrypi/pico-examples/tree/master/pio)! In MicroPython and CircuitPython, you can create PIO commands to control devices and load them at run time. Supports up to two PIO devices, each with four state machines.
