Adafruit Feather RP2350 with HSTX Port

The Adafruit Feather RP2350 with HSTX Port is a powerful development board built around the Raspberry Pi RP2350 microcontroller. Its dual-core ARM Cortex-M33 processor runs at 150MHz and is paired with 520KB SRAM and 8MB SPI Flash. The RP2350 also provides hardware floating-point support and can be used with CircuitPython, MicroPython, Arduino and C/C++.

A 22-pin HSTX connector provides access to eight consecutive GPIO pins and the RP2350 High Speed Transmit peripheral, which can drive four differential data lanes for applications such as DVI output. The board also features USB-C, STEMMA QT, an SWD debug connector and built-in LiPoly battery charging. This version has no PSRAM installed but includes a footprint for an optional external PSRAM chip.
