Product description: ItsyBitsy RP2040 - board with RP2040 microcontroller - Adafruit 4888
ItsyBitsy RP2040 from Adafruit is a board equipped with RP2040 microcontroller. It is even smaller and more compact than the Feather family of products, but it is not inferior to them in terms of functionality. It features a chip that has two ARM Cortex M0+ cores running at 125 MHz, 264 kB of SRAM, 8 MB of FLASH memory. It is equipped with 2 I2C interfaces, 2 x SPI, 2 x UART and 16 PWM channels.
The platform supports the popular programming languages MicroPython, CircuitPython and C/C++, which can be uploaded to 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.
The board has a microUSB connector.
