At the heart of the RP2350-One board lies the new powerful RP2350A microprocessor chip designed by Raspberry Pi. It features a unique hybrid architecture that allows the user to choose between a dual-core Arm Cortex-M33 with FPU and a dual-core Hazard3 RISC-V, with an operating frequency of up to 150 MHz. This flexibility provides the ideal platform for running demanding computational processes, while offering 520KB SRAM and 4MB on-board Flash memory for comfortable storage of your code and data.

The Waveshare RP2350-One board is designed for maximum ergonomics and ease of use, featuring an integrated male PCB USB Type-A connector that allows direct connection to a computer without the need for additional cables. At the same time, its side edges have castellated holes, allowing direct placement and soldering of the unit onto other carrier boards as a standalone SMD component. This dual design makes it extremely versatile for both rapid prototyping and mass production.

Despite its extremely small size, the unit offers 29 multifunctional GPIO pins, supporting 2x SPI, 2x I2C, 2x UART, 4x 12-bit ADC channels, as well as 16x adjustable PWM channels. Additionally, it includes 12 programmable PIO state machines (Programmable I/O) for creating custom peripheral protocols without burdening the processor. With an integrated WS2812 RGB LED, BOOT/RESET buttons, temperature sensor, and Drag-and-Drop programming capability via USB, it provides a complete solution for any modern application.
