Raspberry Pi Pico - Geen WiFi - zonder headers

The Raspberry Pi Foundation has made its own counterpart to the well-known Arduino: the Raspberry Pi Pico. On this board is an internally developed chip, the RP2040, which has 2 ARM Cortex-M0 + cores with a clock speed of 133 Mhz, 256KB RAM, 30 GPIO pins and a wide spectrum of interface options. Along with 2MB on-board QSPI-Flash memory for code and data storage.

All of that comes the small size of 21mm x 51.3mm x 3.9mm and weighs only 3 grams. Programmable in C ++ or MicroPython.

What is a controller?

The Raspberry Pi Pico is not a successor to the Raspberry Pi v4. The Raspberry Pi's as we know them before are processors. Strong chips that are able to contain a complete operating system, and perform multiple tasks at the same time. However, the Raspberry Pi Pico is a controller. A much simpler chip, which is capable of (in principle) 1 task. As there is no operating system running on it, you will have to program everything yourself. This is ideal if you want to perform simple tasks, such as reading out the temperature, and color a light red or blue based on this. Or delegated tasks, such as reading a command from the USB port, then flashing a row of lights in your chosen pattern... Or sounding an alarm when someone walks through a motion sensor. The Pico is already sufficiently suitable for this!
