Embedded Beginner: Master Datasheets in 5 Mins with Pi Pico
A beginner-friendly breakdown of Raspberry Pi Pico's circuits: power, clock, BOOT, debug, and GPIO — understanding dev boards from hardware up.
COMPONENTS
PROJECT DESCRIPTION
【Preliminary Note】The original hardware example in this article was written based on the RP2040. The actual hardware used in this hands-on demonstration features the W55RP20 as the main controller chip. The circuit logic and UF2 flashing operation principles are universally applicable, with only the main controller model differing. The original chip model mentioned in the circuit descriptions below is provided for reference purposes only.
Basic Parameters of the Pico Development Board
It adopts the RP2040 microcontroller chip independently designed by the official Raspberry Pi team;
Equipped with a dual-core ARM Cortex M0+ processor, it features a flexible clock with an operating frequency of up to 133MHz;
It features a built-in 264KB SRAM and 2MB on-chip flash, and adopts a stamp-hole design that can be directly soldered and integrated onto the baseboard independently designed by users.
USB 1.1 host and device support;
Supports low-power sleep and hibernation modes;
It can be recognized as a mass storage device via USB for drag-and-drop program download;
