Raspberry Pi Pico: The $4 advanced Microcontroller based on RP2040 Dual Core ARM Cortex-M0+
Raspberry Pi Foundation is a research and development company that never fails to surprise its users with advanced products. On the 21st  of January, Raspberry Pi came up with a powerful and advanced micro-controller at the economical price of $4. Raspberry Pi Foundation came into the market intending to provide affordable, High-Performance, and programmable products so that more people can learn about programming. At the start of the year 2021, Raspberry Pi launched its powerful micro-controller “Raspberry Pi Pico” with ultra-modern features like RP2040 Dual Core ARM Cortex-M0+ clocked at 133MHz, 256KB RAM, 30 GPIO pins, and a broad range of interfacing options.Raspberry Pi Pico


Raspberry Pi developed RP2040, a technologically advanced Dual-Core ARM microcontroller that would make the users work efficiently. Raspberry Pi Pico is paired with 2MB of onboard QSPI Flash memory for code and data storage. Raspberry Pi designed RP2040 or Raspberry Pi Pico as a free-standing system with powerful peripherals, memory, and processor that a user can utilize into an embedded system. It would provide new degrees of freedom to MCU users that would increase the horizon of the users. The post-fix numeral on RP2040 comes from the following

  1. Number of processor cores
  2. Loosely which type of processor (M0+)
  3. floor(log2(ram / 16k)) 
  4. floor(log2(non-volatile / 16k)) or 0 if no onboard non-volatile storageRP2040 - Raspberry Pi Pico

RP2040 Block Diagram

The basic idea behind the development of Raspberry Pi Pico is to enhance the experience of users with hardware and software. It is a powerful product with advanced peripherals that made it perfect for users that want to explore hardware by using their creativity. If you want to understand Raspberry Pi Pico deeply then check the block diagram mentioned below

In Raspberry Pi Pico Debug is available via the SWD interface and Internal SRAM is arranged in banks that can contain code or data and is accessed via dedicated AHB bus fabric connections, allowing bus masters to access separate bus slaves without being stalled. A user can run Raspberry Pi Pico GPIO pins directly, or from a variety of dedicated logic functions as per their requirements and resources. Raspberry Pi Pico is comprised of DMA bus masters to offload repetitive data transfer tasks from the processors. There are Flexibly configurable PIO controllers that can be used to provide a wide variety of IO functions which would provide a better experience to the users.

Programming Language

A user can configure the Raspberry Pi Pico as per their knowledge of their programming language. One can program Raspberry Pi PICO by using following languages
