Description:
The Raspberry Pi
Pico is a microcontroller board based on the RP2040, a
custom-designed microcontroller. This board is designed for ultra-low power
operation and is ideal for a wide range of embedded and DIY projects.
The heart of
the Raspberry Pi Pico is the RP2040 microcontroller,
featuring a dual-core ARM Cortex-M0+ processor that operates at a
clock speed of up to 133 MHz. The board also includes 264KB of
SRAM and 2MB of onboard QSPI flash memory, providing sufficient space
to store code and data.
While the Pico does not come
with built-in Wi-Fi, Ethernet, or Bluetooth, it can be easily connected to
external modules using SPI, UART, or I2C interfaces,
providing flexibility for various connectivity needs.
One of the standout features
of the Pico is its Programmable I/O (PIO) system, which allows
for advanced custom I/O configurations that can be useful in specialized
applications. The board is designed to be simple to use, with a micro USB
port for power and data transfer, and it can also be configured as
a mouse, keyboard, or other USB devices. Additionally,
the Pico supports drag-and-drop programming, allowing you to
upload code easily by connecting it to a computer.
