Adafruit Feather RP2350 with HSTX Port

The Adafruit Feather RP2350 with HSTX Port is a powerful and compact development board in the Feather form factor, designed to leverage the new Raspberry Pi RP2350 microcontroller chip. It features a dual M33 core running at 150 MHz, 8MB SPI flash storage, and an optional 8MB PSRAM spot. This board is ideal for IoT and embedded projects needing substantial memory and high-speed data transmission capabilities.

This battery-powered dev board comes with an integrated 22-pin HSTX output port, Stemma QT connector for easy sensor and peripheral integration, debug SWD interface, and built-in USB Type-C connector for programming and power. It supports multiple communication protocols including two I2C controllers, two SPI controllers, and two UARTs, alongside 24 PWM channels, making it versatile for various application needs.

The Feather RP2350 also features a built-in 200mA+ LiPo charger with indicator LED, RGB NeoPixel for full-color status indication, and a user-friendly bootloader mechanism for easy firmware updates. Compatible with CircuitPython, MicroPython, C/C++, and Arduino, it is a great choice for developers looking for a high-performance, flexible microcontroller board with extensive peripheral options.
