# Adafruit QT Py ESP32 Pico ## Overview ![](https://cdn-learn.adafruit.com/assets/assets/000/111/953/medium800/adafruit_products_QTP_top.jpg?1653428809) This development board is like when you're watching a super-hero movie and the protagonist shows up in a totally amazing costume in the third act and you're like 'OMG! That's the hero and they're here to kick some serious butt!" but in this case it's a microcontroller. This QT Py board is a thumbnail-sized PCB that features the **ESP32-Pico-V3-02** , an all-in-one chip that has an **ESP32 chip with dual-core 240MHz Tensilica processor** , **WiFi** and **Bluetooth classic + BLE** , adds a bunch of required passives and oscillator, **8 MB of Flash memory** and **2 MB of PSRAM**. We add a USB to serial converter chip, some more passives, an antenna, USB C, buttons, NeoPixel and QT connector to outfit this super-hero chip for any task you want to throw it at. ![](https://cdn-learn.adafruit.com/assets/assets/000/111/954/medium800/adafruit_products_QTP_back.jpg?1653428818) At the core of ESP32-PICO-V3-02 is the ESP32 (ECO V3) chip, which is a single 2.4 GHz Wi-Fi and Bluetooth combo chip designed with TSMC’s 40 nm low-power technology. ESP32-PICO-V3-02 integrates all peripheral components seamlessly, including a crystal oscillator, flash, PSRAM, filter capacitors, and RF matching links in one single package. This makes it perfect for stuffing into such a small space as the QT Py. **Please note ** the QT Py ESP32 Pico does not have native USB support - instead there's a USB to serial converter chip. This means it _cannot_ act like a USB keyboard or mouse - but it does have BLE and BT classic so you could do wireless. ![](https://cdn-learn.adafruit.com/assets/assets/000/111/955/medium800/adafruit_products_QTP_STEMMA_side.jpg?1653428834) [OLEDs](https://www.adafruit.com/?q=qt+oled&main_page=category&cPath=1005&sort=BestMatch)! [Inertial Measurement Units](https://www.adafruit.com/?q=qt+imu&main_page=category&cPath=1005&sort=BestMatch)! [Sensors a-plenty](https://www.adafruit.com/?q=qt+sensor&main_page=category&cPath=1005&sort=BestMatch). All plug-and-play thanks to the innovative chainable design: [SparkFun Qwiic](https://www.sparkfun.com/qwiic)-compatible [STEMMA QT](https://learn.adafruit.com/introducing-adafruit-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](https://www.adafruit.com/product/4528) will also work with this adapter cable. The pinout and shape are [Seeed Xiao](https://wiki.seeedstudio.com/Seeeduino-XIAO/) compatible, with castellated, solderable pads. In addition to the QT connector, we also added an **RGB NeoPixel**  (with controllable power pin to allow for ultra-low-power usage),  **a reset button** (great for restarting your program or entering the bootloader), and a button on GPIO 0 for entering the ROM bootloader or for user input. This board runs Arduino like a dream, or use the ESP IDF for more control over your projects. ![](https://cdn-learn.adafruit.com/assets/assets/000/111/956/medium800/adafruit_products_QTP_top_header.jpg?1653428846) - Same size, form-factor, and pin-out as Seeed Xiao - **USB Type C connector ** - [If you have only Micro B cables, this adapter will come in handy](https://www.adafruit.com/product/4299)! - **ESP32-V2-03 Dual Core 240MHz Xtensa processor** - the ESP32 you know and love, with the latest engineering fixes.
