The Raspberry Pi used its proprietary chip called the RP2040, an entirely new microcontroller chip designed by the foundation in the United Kingdom.
The RP2040 chip features Dual-core Arm Cortex-M0 + 133MHz processor with 264KB internal RAM and up to 16MB of off-chip storage space.
There are 26 GPIO pins, including 3 analog ports, a micro-USB port and a temperature sensor, and it does not come with support for wireless or bluetooth, and costs $ 4.
And like other microcontrollers, the Raspberry Pi Pico has dozens of input and output pins on either side of the device.
These pins are important because they act as an interface with other components, so you can make the microcontroller interact with the LED light, get data from various sensors, show some information on the screen, etc.
The chip includes a wide range of input and output options, including I2C, SPI, and PIO. To support endless possible applications for this small package.
Microcontrollers allow controlling other parts or other devices, and although you can do this with regular Raspberry Pi, microcontrollers are specially designed to interact with other things.
You can start developing your project by using this electronics prototype building base to avoid soldering, and you can pair it with a small battery that can run for weeks or even months.
And unlike computers, microcontrollers do not run traditional operating systems, as their code runs directly through the chip.
You can connect your device to the computer using a micro-USB port, and run the Raspberry Pi Pico while pressing the button, and the device will appear on the computer as an external disk.
The Raspberry Pi Pico board is programmable via C and MicroPython, and is adaptable to a wide range of applications and skill levels.
The Raspberry Pi wants to allow others to benefit from its chip design I reached out to Adafruit, Arduino, Pimoroni, and Sparkfun so they could build their own boards with the RP2040 chip so that there was a complete ecosystem for the devices that powered the RP2040 chip.
