RP2350-USB-A is a mini RP2350 development board featuring a USB expansion port, compatible with USB 2.0/1.1 transmission. It includes 15 multi-function GPIO pins in a compact board design, with half-hole PCB edges for easy and quick integration into projects. The board is built around the official RP2350 microcontroller chip. It features a unique dual-core and dual-architecture setup with a dual-core ARM Cortex-M33 processor and dual-core Hazard3 RISC-V core processor, supporting a flexible clock frequency up to 150MHz. Equipped with 520KB of SRAM and 2MB on-chip Flash memory. Features stamp-hole design for direct soldering onto user-designed baseboards. Supports drag-and-drop programming via USB by appearing as a mass storage device. Provides 2 SPI interfaces, 2 I2C interfaces, 2 UART interfaces, 4 12-bit ADC channels, and 14 controllable PWM channels. Includes accurate on-chip clock and timer functions. Built-in temperature sensor. On-chip accelerated floating-point library. 12 programmable I/O (PIO) state machines for custom peripheral support.
