This dev board is a breakout board for the RP2040 microprocessor, similar in size to the Raspberry Pi Pico but slightly lower in cost with a few welcome extras. Featuring a dual-core ARM Cortex-M0+ processor with a flexible clock running up to 133MHz and 264kB of internal SRAM. The RP2040 can support up to 16MB of off-chip flash, and this board comes populated with 4MB. Some other notable features include a wide range of flexible I/O options (I2C, SPI, UART, ADC, PWM, etc), programmable I/O support (PIO), USB 1.1 Host and Device support, and the list goes on.
