Waveshare RP2350A USBA to USBC

Overview

Upgraded with Raspberry Pi’s second-generation RP2350 microcontroller (A4 revision), the Waveshare RP2350-USB-A delivers high-performance processing in a thumb-sized footprint. Its dual USB arrangement—a native Type-C port for power/programming and an onboard USB-A female connector—enables advanced PIO-driven USB Host and Device interactions (such as emulating keyboards, mice, or pass-through CDC converters) directly on the hardware.

The board uses castellated holes along its edges, allowing developers to solder header pins for prototyping on a breadboard or directly mount the board onto a custom carrier PCB.

Key Features

• Onboard USB Expansion: Built-in USB-A port compatible with USB 2.0/1.1 protocols, supplemented by a USB Type-C port for main power and data connectivity.

• Dual-Architecture Core: Powered by the Raspberry Pi RP2350 chip featuring dual ARM Cortex-M33 cores and dual Hazard3 RISC-V cores running at up to 150 MHz.

• Memory & Storage: 520 KB on-chip SRAM paired with 2 MB onboard QSPI Flash memory.

• Extensive Peripheral Access: 15 multi-function GPIO pins routed to breadboard-friendly castellated pinouts.

• PIO State Machines: 12 Programmable I/O (PIO) state machines to construct custom digital interfaces and hardware peripherals.

• Surface-Mount Ready: Castellated PCB design enables direct soldering onto carrier PCBs without extra headers.

• Multi-Language Support: Fully compatible with C/C++ (Pico SDK, VS Code) and MicroPython.

• Integrated Hardware: Onboard BOOT and RESET buttons for quick flashing, built-in temperature sensor, and controllable PWM channels.
