Trinkey QT2040 - RP2040 microcontroller board - USB - STEMMA QT - Adafruit 5056

The Trinkey QT2040 from Adafruit is a board equipped with the RP2040 microcontroller. It is equipped with a chip that has two ARM Cortex M0+ cores running at 125 MHz, 264 kB of SRAM, 8 MB of FLASH memory. It also has STEMMA QT connectors and a USB type A connector, which can be used to connect it to e.g. a computer. The Trinkey QT2040 also has four M2.5 mounting holes.

The platform supports the popular programming languages MicroPython, CircuitPython and C/C++, which can be loaded into the memory via the USB interface using the built-in UF2 Bootloader or an external programmer via the SWD interface. The Feather RP2040 features a red LED and a single Neopixel RGB LED that can be programmed using CircuitPython.

Adafruit Trinkey QT2040 is equipped with STEMMA QT connector, which allows you to connect different types of sensors without soldering. This connector uses the SCL and SDA pins for the I2C interface.

STEMMA conne ctors are 3 or 4 pin JST PH connectors. They make it easy to connect and read various sensors and devices without soldering. STEMMA 4-pin J ST PH are larger connectors with 2.0 mm pitch for I2C. Whereas the 3-pin J ST PH connector is a 2.0 mm raster connector forPWM / analog / digital use .
