With its state-of-the-art power and RF performance, this SoC is an ideal choice for a wide variety of application scenarios relating to the Internet of Things (IoT), wearable electronics, and smart homes.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note \u003c\/strong\u003ethe QT Py ESP32-S2 has a single-core 240 MHz chip, so it won't be as fast as ESP32's with dual-core. Also, there is no Bluetooth support. However, we are super excited about the ESP32-S2's native USB which unlocks a lot of capabilities for advanced interfacing!\u003c\/p\u003e\n\u003cp\u003eThis ESP32-S2 mini-module we are using on the QT Py comes with 4 MB flash and 2 MB PSRAM so you can buffer massive JSON files for parsing!\u003c\/p\u003e\n\u003cp\u003eOLEDs! Inertial Measurement 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. Seeed Grove I2C boards will also work with this adapter cable.\u003c\/p\u003e\n\u003cp\u003ePinout and shape are Seeed Xiao compatible, with castellated pads so you can solder it flat to a PCB. In addition to the QT connector, we also added an \u003cstrong\u003eRGB NeoPixel\u003c\/strong\u003e (with controllable power pin to allow for ultra-low-power usage), \u003cstrong\u003ea reset button\u003c\/strong\u003e (great for restarting your program or entering the bootloader) and a button on GPIO 0 for entering the ROM bootloader or for user input\u003c\/p\u003e\n\u003cp\u003eRuns Arduino like a dream, and CircuitPython projects are fantastically fun.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSame size, form-factor, and pin-out as Seeed Xiao\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUSB Type C connector \u003c\/strong\u003e- If you have only Micro B cables, this adapter will come in handy!\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eESP32-S2 240MHz Tensilica processor \u003c\/strong\u003e- the next generation of ESP32, now with native USB so it can act like a keyboard\/mouse, MIDI device, disk drive, etc!\u003c\/li\u003e\n\u003cli\u003e4 MB Flash \u0026amp; 2 MB PSRAM\u003c\/li\u003e\n\u003cli\u003eNative USB supported by every OS - can be used in Arduino or CircuitPython as USB serial console, MIDI, Keyboard\/Mouse HID, even a little disk drive for storing Python scripts.\u003c\/li\u003e\n\u003cli\u003eCan be used with \u003cstrong\u003eArduino IDE\u003c\/strong\u003e or \u003cstrong\u003eCircuitPython\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in RGB NeoPixel LED\u003c\/strong\u003e with power control to reduce quiescent power in deep sleep\u003c\/li\u003e\n\u003cli\u003eBattery input pads on underside with diode protection for external battery packs up to 6V input\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e13 GPIO pins:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003e11 on breakout pads, 2 more on QT connector\u003c\/li\u003e\n\u003cli\u003e10 x 12-bit analog inputs (SPI high speed pads do not have analog inputs)\u003c\/li\u003e\n\u003cli\u003e8-bit analog output DAC\u003c\/li\u003e\n\u003cli\u003ePWM outputs on any pin\u003c\/li\u003e\n\u003cli\u003eTwo I2C ports, one on the breakout pads, and another with STEMMA QT plug-n-play connector\u003c\/li\u003e\n\u003cli\u003eHardware UART\u003c\/li\u003e\n\u003cli\u003eHardware SPI on the high speed SPI peripheral pins\u003c\/li\u003e\n\u003cli\u003eHardware I2S on any pins\u003c\/li\u003e\n\u003cli\u003e5 x Capacitive Touch with no additional components required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e3.3V regulator with \u003cstrong\u003e600mA peak output\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eLight sleep at 2~4mA\u003cstrong\u003e\u003cem\u003e, \u003c\/em\u003e\u003c\/strong\u003edeep sleep at ~70uA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset switch \u003c\/strong\u003efor starting your project code over, boot 0 button for entering bootloader mode\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eReally really small\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":50076297887977,"sku":"0000945","price":22.75,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0790\/8006\/3209\/files\/f6222ed0-b93882_b15ea19fcbb041599a18557a69609f1d_mv2.jpg?v=1769545541","url":"https:\/\/www.tinkertailor.ca\/products\/adafruit-esp32-s2-qt-py-wifi-dev-board-w-stemma-qt","provider":"Tinker Tailor","version":"1.0","type":"link"}
