Adafruit Feather RP2040 Adalogger - 8MB Flash with microSD Card - STEMMA QT / Qwiic

This is the Adafruit Feather RP2040 Adalogger - our take on an 'all-in-one' RP2040 data-logger (or data-reader) with built-in USB, battery charging, and a microSD holder ready to rock! We have other boards in the Feather family, check'em out here The RP2040 Adalogger is the same size and shape as a Feather and is intended to make your next data logging or data reading project super easy. Micro SD card socket wired for SPI or SDIO? Yes! STEMMA QT / Qwiic connector for fast I2C? Of course! Neopixel? It's a-glowin' This board will work excellently with Arduino or CircuitPython/MicroPython for any data recording/retreiving projects. At the Feather's heart is an RP2040 chip, clocked at 133 MHz and at 3.3V logic, the same one used in the Raspberry Pi Pico. This chip has a whopping 8MB of onboard QSPI FLASH and 264K of RAM! This makes it great for buffering and processing data before writing it to the SD card.
