We all are familiar with the Raspberry Pi. It has outranked all mini desktop computers for decades of computing history. Nay, it has even become computing history. Although extremely famous for extremely cheap and tiny computers, Raspberry Pi had never tried to enter the electronic world of microcontrollers. Until now. With the announcement and release of Raspberry Pi Pico, the well known brand instantly rooted itself deeply into the field of electronics. Arduino has always been the leading supplier of Microcontrollers. Is that about to change? Let's have a closer look at what the new Raspberry Pi Pico has to offer.
RP2040 Processor
The Pi Pico has its own custom-made processor, the RP2040. The processor is designed for Microcontrolling. It has all the features that you might ever need, and its learning curve ranges from beginner to very intermediate learners. The "2" in the processor's name stands for dual-core. Imagine having two cores in a processor made for miniature circuits. Keep that image in mind because it's going to get crazier. This processor can reach to speeds up to 133 MHz. This powerful processor allows for many power-consuming components attached together and leaves out plenty of room for more calculations. All of that in a small chip, the size of a fingernail.
Wireless connectivity!
A microcontroller that fits in half your palm, now with wireless connectivity! The latest Pi Pico models, Pico W and Pico WH, now support a fully equipped 2.4Hz Wireless connectivity card. The applications know no bounds. Any data from sensors and components can direct reach your computer connected with LAN or maybe a server and put online. Only sky's the limit. The wireless connectivity feature brings this already sophisticated piece of hardware above all other microcontrollers.
