Adafruit Metro RP2350 with PSRAM
The Adafruit Metro RP2350 with PSRAM upgrades the Metro RP2350 with an additional 8 MB of QSPI PSRAM for projects that need extra dynamic memory. Powered by the Raspberry Pi RP2350 dual-core ARM Cortex-M33 at 150 MHz with 520 KB SRAM, 16 MB flash, and a 5V buck converter supporting up to 2A output, this is a seriously capable development board in the standard Metro/UNO shield-compatible form factor.
The board features a 22-pin HSTX FPC port for DVI video output (or 12 extra GPIO), USB host breakout pads, a microSD card slot, and full support for CircuitPython, Arduino, MicroPython, and C/C++.
Key Features
- RP2350 Dual-Core ARM Cortex-M33 @ 150 MHz – Also supports dual RISC-V cores, with floating point unit
- 520 KB SRAM + 8 MB PSRAM – Massive memory for buffers, images, and complex applications
- 16 MB QSPI Flash – ~14 MB available for CircuitPython files
- 37 Available GPIO – 23 on headers, 12 on HSTX port, 2 for USB host; 6 analogue inputs
- MicroSD Card Socket – SPI-connected with additional SDIO pins
- 22-Pin HSTX FPC Port – 3-lane differential for DVI video output or 12 extra GPIO (Pi 5-compatible pinout)
- USB Host Breakout Pads – Controllable 5V power with D+/D− for bitbang USB host
- 5V Buck Converter (TPS563201) – 6–17V DC input, up to 2A output
- UNO Shield Compatible – Standard Metro form factor
- USB-C – Power and data
- 6–17V DC Jack – With on/off switch
- STEMMA QT / Qwiic Port – Solderless I2C connection
- RX/TX Switch – Swap D0/D1 assignments for Arduino UART or RP2350 native order
- PicoProbe Debug Port – 3-pin JST SH compatible
- UF2 Bootloader – Hold BOOTSEL during boot for drag-and-drop firmware updates
- Hardware Security – SHA-256 accelerator, TRNG, optional boot signing with OTP storage
RP2350 Peripherals
- 2× UART, 2× SPI, 2× I2C controllers
- 24× PWM channels
- USB 1.1 controller with host and device support
