We designed and prototyped an RP2350 Metro a few months ago, and it worked OK, but we were really short on pins, which meant a lot of annoying compromises – so we ended up only fabbing the RP2350 Feather to start.
With that design flying off the shelves, It’s time to revisit the Metro.
We wanted to jam-pack this design, and with the extra GPIO on the B we have plenty of peripherals: the 22-pin HSTX for DVI output, Stemma QT port, NeoPixel, JST 3-SH SWD debug port, 16MB flash, an extra spot for PSRAM, MicroSD card with SPI or SDIO connections, and 5V buck converter that can give us 2 Amp easily, which we’ll need since we also have a USB Host port pinout for connecting USB peripherals.
We even managed to get a couple of niceties like switchable power for the USB host power, a USB boot button as user input, and an SD card detect GPIO.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
