Waveshare RP2040-One Microcontroller Board - 4MB Flash USB-A Development Board

About This Product

Hey makers and developers, this waveshare RP2040-One is seriously cool for your next electronics project! It's built around the same RP2040 chip that powers the Raspberry Pi Pico, but with some awesome upgrades. The onboard USB-A connector means you can literally plug it directly into your computer - no cables needed, which is so convenient. You get 4MB of flash memory (way more than the standard Pico), plus 29 multi-function GPIO pins with 20 available through the edge connector and others via solder points. The castellated edges are genius - you can solder this directly onto your own PCBs like a module. It features that dual-core Arm Cortex M0+ processor running up to 133MHz, 246KB of SRAM, and all the peripherals you'd expect including SPI, UART, ADC, PWM, and those amazing programmable I/O (PIO) state machines. Programming is a breeze with drag-and-drop mass storage support, and it works with C/C++ and MicroPython. Whether you're building IoT devices, robotics, custom controllers, or just learning embedded systems, this board gives you professional features in a compact, plug-and-play package. The documentation and SDK are comprehensive too, so you can get started right away. For a development board that combines convenience with serious capability, the RP2040-One is definitely worth checking out!
