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.

The 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.

Key Features

  • ESP32 Dual-Core Xtensa – 240 MHz with 8 MB flash and 2 MB PSRAM
  • Wi-Fi 2.4 GHz – Full Wi-Fi with TLS/SSL support
  • Bluetooth Classic + BLE – Both classic Bluetooth and BLE for wireless connectivity
  • USB-C Connector – USB-to-serial converter for programming and debugging
  • STEMMA QT / Qwiic Connector – Plug-and-play I2C for sensors and accessories
  • RGB NeoPixel LED – Built-in with controllable power pin for ultra-low-power sleep
  • 13 GPIO Pins – 10× 12-bit ADC, 2× 8-bit DAC, PWM on any pin, 8× capacitive touch
  • Two I2C Ports – One on breakout pads, one on STEMMA QT connector
  • Hardware UART, SPI & I2S – Full peripheral support
  • 3.3 V Regulator – AP2112 with 600 mA peak output
  • Battery Input Pads – On the underside with diode protection for up to 6 V
  • Low Power Modes – Light sleep at ~4 mA, deep sleep at ~70 µA
  • Reset & Boot Buttons – Reset switch and GPIO 0 boot button
  • Seeed Xiao Compatible – Same size and pinout with castellated pads

Also Consider

  • QT Py ESP32-S2 – Native USB with CircuitPython support (no Bluetooth)
  • QT Py ESP32-S3 – Native USB + Wi-Fi + BLE with CircuitPython support
  • QT Py ESP32-C3 – RISC-V core with Wi-Fi + BLE (no Bluetooth Classic)
  • QT Py RP2040 – Dual-core ARM with native USB (no Wi-Fi)

Ideal For

  • Wi-Fi and Bluetooth IoT projects
  • Compact wireless sensors and controllers
  • Battery-powered low-power applications
  • Projects requiring Bluetooth Classic (audio, SPP)
  • Embedding into custom PCBs via castellated pads
Note: 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.
