Raspberry Pi Pico - RP2040 Microcontroller Chip
Care for another slice of Raspberry Pi? The UK computer and programming hardware foundation has just released the Raspberry Pi Pico, an RP2040 microcontroller chip. Like their other Pi-namite computers and products, the Pi Pico is small and minimalist, designed for both budding and advanced programmers, and costs about as much as a piece of actual raspberry pie to buy.
The Pico's RP2040 microcontroller chip is fast and fiery, with a dual-core Arm Cortex-M0+ processor, 264KB internal RAM, and support for up to 16MB of off-chip Flash. Input / output options I2C, SPI, and Programmable I/O (PIO). With the RP2040 as its backbone, makers can program the Raspberry Pi Pico (in C or MicroPython) to do anything "from controlling appliances to operating a light display."
For beginners, Raspberry Pi has put together a Get Started with MicroPython on Raspberry Pi Pico manual to guide you.
