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.\n\nThe 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.\n\nKey Features\n\n\nRP2350 Dual Cortex-M33 – 150 MHz with FPU (also supports dual RISC-V cores), 520 KB SRAM, 8 KB OTP\n\n8 MB QSPI PSRAM – AP6404L chip soldered on, perfect for large buffers, framebuffers, and data-heavy projects\n\n8 MB QSPI Flash – Stores firmware and CircuitPython/MicroPython code and files (~7 MB usable with Python)\n\n29 GPIO Pins – 21 on Feather headers, 8 on the 22-pin HSTX connector (usable as general GPIO too)\n\nFour 12-bit ADCs – One more analogue input than Pico 2\n\n24 PWM Channels – For servos, LEDs, motor control, and more\n\n12 PIO State Machines – Three PIO blocks for custom peripherals and protocols\n\nUSB Type C – Built-in ROM UF2 bootloader and serial port debugging\n\nSTEMMA QT / Qwiic Connector – Plug-and-play I2C sensor connectivity with no soldering\n\nBuilt-in LiPo Charger – 200 mA+ charging with status LED; disable via jumper for non-rechargeable batteries\n\nRGB NeoPixel + Red LED – NeoPixel for full-colour status indication, red LED on pin #7\n\nSWD Debug Port – 3-pin JST SH connector compatible with Pico Probe\n\nHardware Security – SHA-256 accelerator, true random number generator (TRNG), TrustZone secure boot with OTP key storage\n\n500 mA 3.3 V Regulator – 12 MHz crystal, 4 mounting holes\n\n\nAlso Available\n\n\nFeather RP2350 – Same board without PSRAM (unpopulated PSRAM footpad available for DIY soldering)\n\n\nProgramming Support\n\n\nCircuitPython – Recommended for beginners; auto-detects and uses the PSRAM chip\n\nMicroPython – Official port available\n\nArduino – Supported via the Earlephilhower core; PSRAM requires specific allocation calls\n\nC/C++ – Full access via the Pico SDK\n\n\n\nNote: Hold the BOOTSEL button while plugging in USB (or pulling RUN/Reset to ground) to enter the UF2 bootloader — do not double-click reset.\n\n\n\nNote: 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.\n\n\nIdeal For\n\nMemory-intensive projects requiring large data buffers or framebuffers\nDVI/HDMI video output via the HSTX connector\nFeatherWing-based IoT and sensor projects needing high performance\nBattery-powered embedded applications\nCircuitPython and MicroPython development with extended memory\n\n\nPackage Contents\n\n1× Adafruit Feather RP2350 with HSTX Port and 8 MB PSRAM (headers not included)\n\n\nSpecifications\n\n\nDimensions: 50.8 × 22.8 × 7 mm (2.0 × 0.9 × 0.28 in)\n\nWeight: 5 g\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":663,"title":"Default Title","sku":"AF-6130","mpn":"ADA6130","price":30.44,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":9,"option1":"Default Title"}]}
