Adafruit QT Py ESP32 Pico

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  wireless.

Features:

• USB Type C connector
• ESP32 V2 03 Dual Core 240MHz Xtensa processor - the ESP32 you know and love, with the latest engineering fixes. Massive user base and thousands of existing projects and libraries to use.
• WiFi, Bluetooth LE and Classic for any IoT project usage
• 8 MB Flash & 2 MB PSRAM
• USB to Serial converter built in with high speed UART for debugging and uploading.
• Can be used with Arduino IDE or MicroPython
• Built-in RGB NeoPixel LED with power control to reduce quiescent power in deep sleep
• Battery input pads on underside with diode protection for external battery packs up to 6V input
• 13 GPIO pins
• 3.3V regulator with 600mA peak output
• Light sleep at 4mA, deep sleep at ~70uA
• Reset switch for starting your project code over, boot 0 button for entering bootloader mode or for user reading
