Waveshare RP2350 Tiny

My tiny dev board disappeared, have you seen it? Ah, there it is! This very compact development board is based on the Raspberry Pi RP2350A microcontroller and packs a mean punch for its size! It combines dual-core Arm Cortex-M33 and Hazard3 RISC-V processors running at speeds up to 150 MHz, making it more than capable of dealing with various projects.

The board includes 520KB of memory and 4MB of storage, so there’s enough space for your code and data. Its castellated edges allow you to solder it directly onto other boards, and it also has an 8-pin FPC connector that works with an adapter board to give you a USB Type-C connection for programming and power.

It has 28 GPIO pins, 20 of which are accessible on the edges, making it easy to connect and communicate with many different devices! The pins support SPI, I2C, UART, ADC, and PWM functions. It also has 12 programmable I/O (PIO) state machines, which let you customise how the board interacts with other hardware, meaning you can add on WS2812B LEDs or more I2C and SPi buses if needed

Programming is simple with drag-and-drop support over USB, and it works with both C/C++ and MicroPython. Guides, SDKs, and tutorials are available to help you get started quickly.
