Adafruit Trinkey QT2040

The Adafruit Trinkey QT2040 is an innovative and compact development board that combines the functionality of a USB key and a development board. Here are some key aspects of its design and features: 1. The Trinkey QT2040 has a unique design that makes it half USB Key and half Adafruit QT Py. It is small and portable, measuring just 1 x 0.7 inches (25.4 x 17.8mm) and 5.5mm thick, which allows it to directly slot into a USB port for programming and use. This design emphasizes ease of use and plug-and-play capabilities. 2. At the heart of the Trinkey QT2040 is the RP2040 microcontroller, a 32-bit Cortex M0+ dual-core processor that runs at approximately 125 MHz. This provides substantial computational power and efficiency for various projects. 3. The Trinkey QT2040 is designed to be compatible with SparkFun Qwiic boards and Seeed Grove I2C boards, making it versatile for various applications. It includes a USB Type A connector with an extra-thick PCB to ensure a snug fit into a USB host port. 4.The board is equipped with an RGB NeoPixel, offering visual output options for your projects. It also includes a reset and bootloader/user button, adding to its functionality. Additionally, it comes with a STEMMA QT Port on the end, expanding its connectivity and compatibility with other devices. 5. The main body of the Trinkey QT2040 is similar in size and mounting holes to most Stemma QT boards, measuring 1.0" x 0.7" with M2.5 holes. This standardized sizing allows for easy integration with other components and projects. In summary, the Adafruit Trinkey QT2040 is a versatile and compact development board that blends the convenience of a USB key with the power of a microcontroller, suitable for a wide range of electronic projects and applications.
