We were running our adafruit.io MQTT demo for a full weekend straight with no hiccups (it would have run longer but we had to go to work, so we unplugged it). This module is very fast \u0026amp; easy to use in comparison to other WiFi modules we've used in the past.\u003c\/p\u003e\u003cp\u003eThis module works with 802.11b, g, or n networks \u0026amp; supports WEP, WPA and WPA2 encryption.  You can connect to your own WiFi networks or create your own with \"Soft AP\" mode, where it becomes its own access point (we have an example of it creating a webserver that you can then control the Arduino's pins). You can clock it as fast as 12MHz for speedy, reliable packet streaming. And scanning\/connecting to networks is very fast, just a second or two.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eYou might be wondering\u003c\/em\u003e why use this when you can get a HUZZAH Feather?

This chip has a whopping 256K of FLASH (8x more than the Atmega328 or 32u4) and 32K of RAM (16x as much)! This chip comes with built in USB so it has USB-to-Serial program \u0026amp; debug capability built in with no need for an FTDI-like chip. For advanced users who are comfortable with ASF, the SWDIO\/SWCLK pins are available on the bottom, and when connected to a CMSIS-DAP debugger can be used to use Atmel Studio for debugging.\u003c\/p\u003e\u003cp\u003eTo make it easy to use for portable projects, we added a connector for any of our 3.7V Lithium polymer batteries and built in battery charging. You don't need to use a battery, it will run just fine straight from the micro USB connector. But if you do have a battery, you can take it on the go, then plug in the USB to recharge. The Feather will automatically switch over to USB power when it's available. We also tied the battery through a divider to an analog pin, so you can measure and monitor the battery voltage to detect when you need a recharge.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHere are some handy specs!

Having this connector means you don't need to do any soldering to get started.\u003c\/p\u003e\n\u003cp\u003eWhat 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.

There is great C\/C++ support, an official MicroPython port, and a CircuitPython port!\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003ch2\u003eQT Py RP2040 Specifications\u003c\/h2\u003e\n\u003cp\u003ePinout and shape is Seeed Xiao compatible, with castellated pads so you can solder it to a PCB with a cut out to allow the bottom components some breathing room.

Instead, that is provided by the external QSPI flash chip. On this board there is 8MB, which is shared between the program it's running and any file storage used by MicroPython or CircuitPython.

What that means is when you want to program new firmware, you can hold down the BOOT button while plugging it into USB (or pulling down the RUN\/Reset pin to ground) and it will appear as a USB disk drive you can drag the firmware onto. Folks who have been using Adafruit products will find this very familiar - we use the technique on all our native USB boards. Just note you don't double-click reset, instead hold down BOOTSEL during boot to enter the bootloader!\u003c\/p\u003e\n\u003cp\u003eThe RP2040 is a powerful chip, which has the clock speed of our M4 (SAMD51), and two cores that are equivalent to our M0 (SAMD21). Since it is an M0 chip, it does not have a floating point unit or DSP hardware support - so if you're doing something with heavy floating point math, it will be done in software and thus not as fast as an M4. For many other computational tasks, you'll get close-to-M4 speeds!\u003c\/p\u003e\n\u003cp\u003eFor peripherals, there are two I2C controllers, two SPI controllers, and two UARTs that are multiplexed across the GPIO - check the pinout for what pins can be set to which. There are 16 PWM channels, each pin has a channel it can be set to (ditto on the pinout).\u003c\/p\u003e\n\u003cp\u003eYou'll note there's no I2S peripheral, SDIO, or camera, what's up with that? Well, instead of having specific hardware support for serial-data-like peripherals like these, the RP2040 comes with the PIO state machine system which is a unique and powerful way to create \u003cem\u003ecustom hardware logic and data processing blocks\u003c\/em\u003e that run on their own without taking up a CPU. For example, NeoPixels - often we bitbang the timing-specific protocol for these LEDs. For the RP2040, we instead use a PIO object that reads in the data buffer and clocks out the right bitstream with perfect accuracy. Same with I2S audio in or out, LED matrix displays, 8-bit or SPI based TFTs, even VGA! In MicroPython and CircuitPython you can create PIO control commands to script the peripheral and load it in at runtime. There are 2 PIO peripherals with 4 state machines each.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cdiv class=\"panel-collapse collapse in\" id=\"tab-technical-details-content\"\u003e\n\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"col-lg-12 col-md-12 col-sm-12 col-xs-12\"\u003e\n\u003cp\u003e\u003cstrong\u003eRP2040 Chip features \u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDual ARM Cortex-M0+ @ 133MHz\u003c\/li\u003e\n\u003cli\u003e264kB on-chip SRAM in six independent banks\u003c\/li\u003e\n\u003cli\u003eSupport for up to 16MB of off-chip Flash memory via a dedicated QSPI bus\u003c\/li\u003e\n\u003cli\u003eDMA controller\u003c\/li\u003e\n\u003cli\u003eFully-connected AHB crossbar\u003c\/li\u003e\n\u003cli\u003eInterpolator and integer divider peripherals\u003c\/li\u003e\n\u003cli\u003eOn-chip programmable LDO to generate core voltage\u003c\/li\u003e\n\u003cli\u003e2 on-chip PLLs to generate USB and core clocks\u003c\/li\u003e\n\u003cli\u003e30 GPIO pins, 4 of which can be used as analogue inputs \u003cstrong\u003e(not all GPIO are brought out on this board)\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003ePeripherals\n\u003cul\u003e\n\u003cli\u003e2 UARTs\u003c\/li\u003e\n\u003cli\u003e2 SPI controllers\u003c\/li\u003e\n\u003cli\u003e2 I2C controllers\u003c\/li\u003e\n\u003cli\u003e16 PWM channels\u003c\/li\u003e\n\u003cli\u003eUSB 1.1 controller and PHY, with host and device support\u003c\/li\u003e\n\u003cli\u003e8 PIO state machines\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli style=\"text-align: left;\"\u003eProduct Dimensions: 21.8mm x 17.8mm x 5.8mm\u003c\/li\u003e\n\u003cli style=\"text-align: left;\"\u003eProduct Weight: 2.2g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":46375205830713,"sku":"xnl1787258168353","price":5.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0795\/9176\/8121\/files\/adafruit-qt-py-rp2040_1.jpg?v=1787258178"},{"product_id":"firebeetle-328p-with-ble-41","title":"FireBeetle 328P with BLE 4.1","description":"\u003cdiv class=\"desc\"\u003e\n\u003cdiv class=\"desCon\"\u003eDFRobot FireBeetle series are low power consumption microcontrollers designed for Internet of Things (IoT) development.
