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. 1. Introduction to Raspberry Pi Pico The Raspberry Pi Pico is a low-cost, high-performance microcontroller development board officially designed by…
