Adafruit Feather RP2350 with HSTX Port and 8MB PSRAM

RP2350 strides confidently into the Feather format, seamlessly integrating with any FeatherWings for a limitless platform expansion. Equipped with 8MB of flash, a 22-pin HSTX output port, and an optional PSRAM spot, it's a powerful dev board packed with advanced features.

This version includes an AP6404L 8 Megabyte PSRAM chip, perfect for managing large buffer sizes in memory. Building on the success of the RP2040, the RP2350 enhances performance with dual M33 cores running at 150 MHz and hardware floating point support, drastically increasing processing speed.

The RP2350 doubles SRAM capacity to 520KB, optimizing MicroPython and CircuitPython applications. It also excels in IoT projects requiring substantial memory buffer space. Additional advancements include 3 PIO blocks, TrustZone secure boot, and a High Speed Transmit (HSTX) peripheral for efficient differential data transmission.

You'll find versatile multiplexed GPIO with 29 pins, including enhanced capabilities such as four 12-bit ADCs, dual I2C, SPI, and UART controllers, alongside 24 PWM outputs. Its USB Type C connector facilitates programming and debugging via the built-in ROM USB bootloader.

The board boasts superior connectivity with two I2C, SPI, and UART peripherals, labeled conveniently for main interface usage. Built-in 200mA+ lipoly charger, reset and Bootloader buttons, and Qt connector ensure easy integration with additional devices, enhancing your project's scope.

Designed to cater to both ease of use and extended capabilities, the RP2350 offers robust programming choices with C/C++, unofficial Arduino, and official MicroPython and CircuitPython support. CircuitPython's compatibility with numerous drivers, sensors, and displays ensures seamless project execution.

Be aware of the A2 version's E9 erratum affecting some GPIO and PIO functions. Utilizing 8.2K or smaller resistors is recommended for applications requiring pulldowns. As of September 2024, the A2 is the sole available version of the RP2350, ensuring cutting-edge performance packed into a classic Feather design.
