▷ #Raspberry Pi Pico ($ 4 microcontroller)

⭐⭐⭐⭐⭐#Raspberry Pi Pico ($ 4 microcontroller)

  •  The Raspberry Pi Pico is a $ 4 microcontroller with a surprise: a proprietary SoC designed by the Raspberry Pi Foundation
  • The #RPi Foundation becomes a #Processor manufacturer
  • The #Raspberry Pi Pico is governed by a small SoC that has been designed by the people in charge of this project. It is the RP2040, which has a dual core ARM Cortex M0 + processor running at 133 MHz, accompanied by 264 KB Of #RAM and 2 MB of onboard storage.

  • That SoC represents the new role of The Raspberry Pi Foundation as a semiconductor manufacturer, and, specifically, of SoC. Those responsible for this project have been working on it since the end of 2016, and in September 2018 they already had a first prototype with which they began to carry out tests.
