RP2350 Raspberry Pi Pico based MCU with USB A

The RP2350 is the ideal solution if you're looking for a compact, powerful, and ready-to-use microcontroller unit. Based on the Raspberry Pi RP2040 chip, this module offers strong dual-core performance with high energy efficiency. The special feature of this version is the integrated USB-A plug, allowing you to connect the module directly to a USB port without an additional cable. This makes the RP2350 perfect for quick prototypes, USB-based projects, or as a direct plug-in interface for controls. The microcontroller runs up to 133 MHz and features 264KB SRAM and 2MB onboard flash memory. You can connect numerous peripherals via GPIOs, including I2C, SPI, UART, and PWM. Programming is easily done via MicroPython or C/C++ using the USB mass storage function. The RP2350 can be used with any USB host systems such as PCs or laptops without requiring additional power supply. The compact design and robust construction make the module particularly suitable for mobile, embedded, or industrial applications. It also serves excellently as a small data logger or control center for sensors. If you need a flexible microcontroller for quick ideas, the RP2350 is the right board for you.

Features:  

• The module is based on the Raspberry Pi RP2040 dual-core processor with 32-bit Arm Cortex-M0+.  
• The maximum clock frequency is 133 MHz, enabling high computing power with low power consumption.  
• The board features 264KB internal SRAM and 2MB onboard QSPI flash memory for programs and data.
