On January 21, 2021, the Raspberry Pi Foundation unveiled their own microcontroller board, the Raspberry Pi Pico, which was announced for $ 4! and further we discuss raspberry pi pico specs.
 

Therefore, after changing the single board computer industry (or single board computer in good French), the foundation intends to tackle the microcontroller industry.

This article will walk you through how to get the raspberry pi pico specs & raspberry pi pico uses or difference between a microcomputer and a microcontroller, what the Raspberry Pico has in its gut, and finally how to use it and where to find documentation to get started.

The Raspberry Pi takes care of heavy computation, network access and storage, while the microcontroller handles analog inputs and I / O with low latency and sometimes offers a standby mode with very low power consumption.

The Raspberry Pi Pico is intended for all craft projects for which a Raspberry Pi is too big or too powerful. Or too expensive. You can program the Raspberry Pi Pico or its System-on-Chip (SoC) with C and Micropython. Microsoft Visual Studio is also supported.

# The technical data of the raspberry pi pico specs

  • Dual-core Arm Cortex-M0+ 133MHz
  • 264KB on-chip RAM
  • Support for up to 16 MB flash memory via dedicated QSPI bus
  • DMA controller
  • Interpolator und Integer Divider Peripherals
  • 30 GPIO pins, including 4 that can be used for analog input
  • 2 × UARTs, 2 × SPI Controllers und 2 × I2C Controller
  • 16 × PWM Channels
  • 1 × USB 1.1 controller and PHY, with host and device support
  • 8 × Raspberry Pi Programmable I/O (PIO) state machines
  • USB mass storage boot mode with UF2 support, for drag-and-drop programming

These specs might go one ear and the other, but the best way to demonstrate the potential of a new Raspberry Pi product is to use it in something cool.

The Raspberry Pi Foundation is working with companies like Arduino, Adafruit and Pimoroni to integrate the new RP2040 chip with other boards and gadgets. There’s a whole list in the blog post announcing the Pico, but a few notable ones include Pimoroni’s PicoSystem game console, Adafruit’s Spring RP 2040 board, and the Arduino

# The Raspberry Pi Pico Board, power supply and format.

The Raspberry Pi Pico card therefore includes the RP2040 microcontroller to offer a more user-friendly format, integrated power supply management, expanded RAM and a few other features.

#The Raspberry Pi Pico, a very small card and 26 GPIO pins.

On the physical level, the Raspberry Pi Pico looks like a 21 × 51 mm board.

The wholesalers receive the Raspberry Pi Pico directly on rolls with several hundred (thousands) units, a so-called “tape and reel” format.

The Pico exposes 26 of the RP2040’s 30 GPIO connections in the form of drilled and weldable pads with a standard spacing of 0.1 inches and reminds you of those of the Raspberry Pi Zero. An additional part enables direct soldering on copper contacts.

The card also has an integrated LED. A push button to activate the USB storage mode (to copy your program to the Raspberry Pi Pico), which can also be used as a classic push button. In addition to a mini-USB connection, via which the Pico is connected to your computer in order to copy your code from your PC to the Pi, and which can also serve as a classic USB connection, for example to connect a probe to the Raspberry.

Finally, it should be noted that the Pico has been designed so that its underside is perfectly flat, so that it can be integrated directly into a “host” card by soldering, which is a big plus for production. of embedded products.

# Microcontroller VS Microcomputer, What’s the Difference & raspberry pi pico uses?

If you’ve undoubtedly used a microcomputer (in the narrower sense of the term you’re currently using when using a smartphone, for example), there is a good chance you’ve never used it (at least you know). a microcontroller.

In summary, a microcomputer is a generalist. It is based on the use of a general purpose microprocessor and can perform several tasks: graphical display; Internet connection; Management of peripheral devices and above all use of an operating system. So it’s a computer like any other, it’s just very small.

A Raspberry Pi is therefore a microcomputer. Still, this is a special case as we can see that programmable GPIO inputs / outputs are also embedded.

Conversely, a microcontroller is usually quite specialized. Instead of doing multiple tasks, you can essentially control peripheral devices using programmable electrical inputs / outputs. In contrast to the microcomputer, the microcontroller therefore does not run an operating system and only executes a program that is loaded into memory before starting.

The microcontroller is therefore much less flexible and powerful in terms of computational capabilities, etc., but it consumes much less power and is better suited for reading probes, controlling electrical peripherals (LEDs, motors, relays, etc., etc.). ) or reading analog instead of digital electrical signals.

# Microcontroller or microcontroller board?

For the sake of precision, it should be noted that a microcontroller in the narrower sense only refers to the electronic chip that combines the memory, the processor and the input / output lines.

The Raspberry Pi Pico is actually a microcontroller card. As such, the microcontroller, which is the RP2040 chip, is expanded to include power management, connectivity, etc. If we talk about the Arduino Uno, probably the most famous of the microcontroller cards, the Arduino is a microcontroller card, and the microcontroller itself is the ATmega328P chip.

The Arduino Uno is probably the most famous microcontroller board.

# The technical characteristics of the raspberry pi pico specs

Let’s talk, let’s talk numbers and see what this newbie is up to. The program includes the technical properties of the microcontroller and the format of the pico card.

#The RP2040 microcontroller.

The Raspberry Pi Pico is therefore based on a brand new microcontroller that was developed directly by the Raspberry Pi Foundation, the RP2040.

We should pay attention to the ambition of the foundation here. In fact, the Foundation preferred to create a completely existing component when it would have been easy to use an existing component or ask a specialized company to customize a component and put the Raspberry Pi brand on it. A bold choice that allows it to offer impressive performance at an unbeatable price.

# Where can I buy the Raspberry Pi Pico?

As is so often the case with the release of a new product by the Raspberry Pi Foundation, stocks of at least a few days can be expected.

As with the more classic versions of the Raspberry Pi, you can find the Raspberry Pi Pico at various online providers. by amazon 

More generally , you can find it on Amazon, as the price is variable, it should still stabilize around € 4 in the days or weeks after its release once stocks return to normal. .

Additionally, it wouldn’t be surprising to find this microcontroller on the websites of electronics specialty retailers in the future.
