## Description

The Adafruit Feather RP2350 with HSTX Port and 8 MB PSRAM is the upgraded variant of the Feather RP2350, featuring a pre-soldered AP6404L 8 MB PSRAM chip for managing large data buffers, display framebuffers, and memory-intensive applications directly in mappable RAM. Combined with dual Cortex-M33 cores at 150 MHz, 520 KB of SRAM, and 8 MB of flash, this is one of the most capable Feathers available. The RP2350 delivers roughly twice the performance of the RP2040 thanks to its M33 cores with hardware floating-point support, three PIO blocks (12 state machines), TrustZone secure boot, and the High Speed Transmit (HSTX) peripheral for driving differential data such as DVI output without overclocking. The 8 MB PSRAM is accessible via chip select on GPIO 8 — CircuitPython detects and uses it automatically, while Arduino and C/C++ projects can allocate from it with specific calls. Key Features RP2350 Dual Cortex-M33 – 150 MHz with FPU (also supports dual RISC-V cores), 520 KB SRAM, 8 KB OTP 8 MB QSPI PSRAM – AP6404L chip soldered on, perfect for large buffers, framebuffers, and data-heavy projects 8 MB QSPI Flash – Stores firmware and CircuitPython/MicroPython code and files (~7 MB usable with Python) 29 GPIO Pins – 21 on Feather headers, 8 on the 22-pin HSTX connector (usable as general GPIO too) Four 12-bit ADCs – One more analogue input than Pico 2 24 PWM Channels – For servos, LEDs, motor control, and more 12 PIO State Machines – Three PIO blocks for custom peripherals and protocols USB Type C – Built-in ROM UF2 bootloader and serial port debugging STEMMA QT / Qwiic Connector – Plug-and-play I2C sensor connectivity with no soldering Built-in LiPo Charger – 200 mA+ charging with status LED; disable via jumper for non-rechargeable batteries RGB NeoPixel + Red LED – NeoPixel for full-colour status indication, red LED on pin #7 SWD Debug Port – 3-pin JST SH connector compatible with Pico Probe Hardware Security – SHA-256 accelerator, true random number generator (TRNG), TrustZone secure boot with OTP key storage 500 mA 3.3 V Regulator – 12 MHz crystal, 4 mounting holes Also Available Feather RP2350 – Same board without PSRAM (unpopulated PSRAM footpad available for DIY soldering) Programming Support CircuitPython – Recommended for beginners; auto-detects and uses the PSRAM chip MicroPython – Official port available Arduino – Supported via the Earlephilhower core; PSRAM requires specific allocation calls C/C++ – Full access via the Pico SDK Note: Hold the BOOTSEL button while plugging in USB (or pulling RUN/Reset to ground) to enter the UF2 bootloader — do not double-click reset. Note: This board ships with the A2 revision of the RP2350, which is affected by the E9 erratum. Some GPIO and PIO functions (high-impedance inputs, internal pull-downs) may require 8.2 KΩ or smaller external resistors as a workaround. Ideal For Memory-intensive projects requiring large data buffers or framebuffers DVI/HDMI video output via the HSTX connector FeatherWing-based IoT and sensor projects needing high performance Battery-powered embedded applications CircuitPython and MicroPython development with extended memory Package Contents 1× Adafruit Feather RP2350 with HSTX Port and 8 MB PSRAM (headers not included) Specifications Dimensions: 50.8 × 22.8 × 7 mm (2.0 × 0.9 × 0.28 in) Weight: 5 g
