An operating system allows us to run many processes in parallel, but it is slower to execute individual tasks. This means that the Pico does not have an operating system because its field of activity is somewhat different: a pure microcontroller usually has simpler tasks that it has to carry out quickly. The features of the Pico read all very well – but what are the technical differences to a Raspberry Pi 4 Model B or a Raspi Zero?įirstly, the most important difference: The Pico is a microcontroller and not a mini-computer. Some have multiple functions: Raspberry Pi Pico pin assignment ( go to PDF) Raspberry Pi Pico vs. The 26 programmable pins can be found in the following locations. The low price in particular is also a highlight. That all sounds very interesting at first. 8 × programmable I/O state machines (PIO) for user-defined peripheral support.2 × SPI, 2 × I2C, 2 × UART, 3 × 12-bit ADC, 16 × controllable PWM channels.Direct soldering on the board is possible. 264 KB SRAM and 2 MB built-in flash memory.Dual-core arm Cortex M0 + processor, flexible clock speed of up to 133 MHz.The officially published specifications of the Pico are as follows: Its direct “competitors” are other microcontrollers such as Arduino or ESP8266. The tiny microcontroller sells for $4 excluding taxes and shipping, making it more than competitive. The new device from the Raspberry Pi Foundation differs from its predecessors. In this article, we will first look at the differences between other Raspberry Pi models and then create our first little program for the Pico. In addition, the Pico comes with many GPIOs on board and even one or the other sensor. We can write our first small application using MicroPython and/or C++. This differs from its “siblings” but is easier to program than seldom before. The Raspberry Pi Foundation has released a pure microcontroller at a super low price: the Raspberry Pi Pico.
