RP2040 is an advanced microcontroller with flexible digital interfaces that has a surprising amount of efficiency and power for a low price in a compact size. It consists of a low-power ARM processor and dual Arm Cortex-M0+ processors(up to 133MHz), embedded 264KB of on-chip RAM, DMA controller, 2 × UARTs, 2 × SPI controllers, and 2 × I2C controllers which let the module run faster. One of the great advantages of this low-cost microcontroller is the inclusion of a powerful new chip, the RP2040, at a worry-free price, which will aid customers in developing cost-effective embedded electronics items or projects.
