The RP2040 is a high-performance, low-cost microcontroller designed by Raspberry Pi to make powerful embedded computing accessible to everyone. Built on 40 nm silicon and packed into a compact 7 mm × 7 mm package, RP2040 delivers exceptional performance, flexibility, and efficiency for modern hardware projects.
At its core, RP2040 features a dual-core Arm Cortex-M0+ processor running up to 133 MHz, capable of handling demanding integer workloads with ease. Its unique bus fabric and six independent SRAM banks allow both cores and DMA engines to operate in parallel without memory contention—extracting maximum real-world performance from the silicon.
Designed to connect effortlessly with the physical world, RP2040 offers rich and flexible I/O, including UART, SPI, I²C, PWM, USB, and the powerful Programmable I/O (PIO) subsystem. The eight PIO state machines let you create custom peripherals in software, enabling support for protocols that don’t even exist yet.
Programming is simple and beginner-friendly thanks to drag-and-drop USB mass-storage programming, while advanced users benefit from low-power modes, on-chip temperature sensing, and optimized integer and floating-point libraries.
Whether you’re building a low-cost IoT device, a high-speed USB gadget, a robotics controller, or an experimental hardware platform, RP2040 delivers big performance in a small, affordable package—true to Raspberry Pi’s mission of efficient, accessible computing for all.
