Feather RP2350 - development board with RP2350 microcontroller and HSTX connector

Description

Feather RP2350 is a versatile and modern development board designed for projects that require high performance and compact dimensions. It features the new RP2350 microcontroller with a dual-core Cortex-M33 running at 150 MHz, providing significantly more computational power than its predecessor, the RP2040. This makes the board ideal for IoT, automation, control systems, real-time applications, and multimedia projects.

The board offers 520 KB of RAM and external 8 MB QSPI Flash memory for storing code, configurations, and user data. It also supports expansion with PSRAM, extending its potential for applications requiring large buffers, such as image or audio processing. Feather RP2350 provides a rich set of interfaces, including I2C, SPI, UART, and 24 PWM channels, ensuring versatility in communication and device control. The included HSTX port enables high-speed differential transmission, for example generating DVI signals without using PIO. The board features a STEMMA QT connector for plug-and-play modules, greatly speeding up prototyping. Additionally, it includes a 200 mA+ LiPo charger and a USB-C port for programming via the UF2 bootloader.

The board includes two RGB NeoPixel LEDs and a red LED for status indication. It is supported by multiple programming environments, including MicroPython, CircuitPython, Arduino, and C/C++, making it suitable for both beginners and advanced developers. Its solid construction, Feather ecosystem compatibility, and wide range of features make the Feather RP2350 with HSTX Port an extremely versatile platform for a broad spectrum of electronic projects. The board is lightweight, energy-efficient, and well-suited for portable, battery-powered applications. Its extensive communication options and high computational power make it an excellent choice for modern embedded systems. Three PIO blocks expand its capabilities for custom protocol handling, while the precise 12 MHz crystal ensures stable timing. Debugging is facilitated via the available SWD connector, making this hardware a reliable solution for demanding electronic system designers.
