Product description: Feather RP2040 - board with RP2040 microcontroller and USB A host - Adafruit 5723
A board from Adafruit - Feather RP2040 with a USB type A host. It is based on the RP2040 microcontroller from the Raspberry Pi Foundation , with a dual-core ARM Cortex M0+ clocked at up to 133 MHz , with 264 kB of RAM and 8 MB of Flash memory operating via the QSPI interface. The module pins include as many as 21x GPIO pins - 4x ADC 12-bit, 2x I2C, 2x SPI, 2x UART, 16x PWM. The Feather RP2040 board can be programmed using MicroPython, CircuitPython or C/C++. The program can be implemented via the USB interface (USB Type C connector), using the built-in UF2 bootloader, or via an external programmer .
