{"title":"Adafruit QT Py ESP32 Pico - WiFi Dev Board with STEMMA QT","handle":"adafruit-qt-py-esp32-pico-wifi-dev-board-with-stemma-qt","url":"/products/adafruit-qt-py-esp32-pico-wifi-dev-board-with-stemma-qt","description":"The Adafruit QT Py ESP32 Pico brings the full power of the classic ESP32 into the tiny QT Py form factor. Built around the ESP32-PICO-V3-02 — an all-in-one module with dual-core 240 MHz Tensilica processor, Wi-Fi, Bluetooth Classic + BLE, 8 MB flash, and 2 MB PSRAM — this thumbnail-sized board is ready for serious IoT projects.\n\nThe ESP32 Pico integrates the processor, crystal oscillator, flash, PSRAM, and RF matching into a single package, keeping the board compact. A USB-to-serial converter provides programming and debugging over USB-C, and the STEMMA QT / Qwiic connector gives you plug-and-play I2C access to hundreds of sensors and accessories. Program it with Arduino or MicroPython.\n\nKey Features\n\n\nESP32 Dual-Core Xtensa – 240 MHz with 8 MB flash and 2 MB PSRAM\n\nWi-Fi 2.4 GHz – Full Wi-Fi with TLS/SSL support\n\nBluetooth Classic + BLE – Both classic Bluetooth and BLE for wireless connectivity\n\nUSB-C Connector – USB-to-serial converter for programming and debugging\n\nSTEMMA QT / Qwiic Connector – Plug-and-play I2C for sensors and accessories\n\nRGB NeoPixel LED – Built-in with controllable power pin for ultra-low-power sleep\n\n13 GPIO Pins – 10× 12-bit ADC, 2× 8-bit DAC, PWM on any pin, 8× capacitive touch\n\nTwo I2C Ports – One on breakout pads, one on STEMMA QT connector\n\nHardware UART, SPI & I2S – Full peripheral support\n\n3.3 V Regulator – AP2112 with 600 mA peak output\n\nBattery Input Pads – On the underside with diode protection for up to 6 V\n\nLow Power Modes – Light sleep at ~4 mA, deep sleep at ~70 µA\n\nReset & Boot Buttons – Reset switch and GPIO 0 boot button\n\nSeeed Xiao Compatible – Same size and pinout with castellated pads\n\n\nAlso Consider\n\n\nQT Py ESP32-S2 – Native USB with CircuitPython support (no Bluetooth)\n\nQT Py ESP32-S3 – Native USB + Wi-Fi + BLE with CircuitPython support\n\nQT Py ESP32-C3 – RISC-V core with Wi-Fi + BLE (no Bluetooth Classic)\n\nQT Py RP2040 – Dual-core ARM with native USB (no Wi-Fi)\n\n\nIdeal For\n\nWi-Fi and Bluetooth IoT projects\nCompact wireless sensors and controllers\nBattery-powered low-power applications\nProjects requiring Bluetooth Classic (audio, SPP)\nEmbedding into custom PCBs via castellated pads\n\n\n\nNote: The QT Py ESP32 Pico does not have native USB — it uses a USB-to-serial converter. It cannot act as a USB keyboard, mouse, or disk drive. For native USB, consider the QT Py ESP32-S2 or ESP32-S3. It does not run CircuitPython.\n\n\nResources\n\nAdafruit QT Py ESP32 Pico Learning Guide\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2241,"title":"Default Title","sku":"AF-5395","price":30.61,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
