Adafruit QT Py ESP32 Pico - WiFi Dev Board 8MB Flash 2MB PSRAM

The QT Py board is a remarkably compact PCB, resembling a thumbnail in size. It showcases the ESP32 Pico V3 02, an integrated chip boasting an ESP32 with a dual-core 240MHz Tensilica processor, along with WiFi, Bluetooth classic + BLE capabilities. The chip is augmented with essential passive components, oscillators, 8 MB of Flash memory, 2 MB of PSRAM, a USB to serial converter chip, supplementary passives, an antenna, USB C, buttons, NeoPixel, and a QT connector. These enhancements equip this exceptional chip to excel in any task it encounters.

Central to the ESP32-PICO-V3-02 lies the ESP32 (ECO V3) chip, a solitary 2.4 GHz Wi-Fi and Bluetooth combination chip crafted using TSMC's 40 nm low-power technology. Seamlessly integrating all peripheral elements, such as a crystal oscillator, flash, PSRAM, filter capacitors, and RF matching links, within a single package, the ESP32-PICO-V3-02 becomes an ideal fit for compact spaces like the QT Py.
