It includes HDMI output (DVI via PicoDVI-compatible GPIO pins), a MicroSD card slot, optional 8 MB PSRAM, 4 MB SPI flash, 46 GPIO pins via dual 30-pin headers, and two USB-C ports. The board is open-source hardware with KiCad files and schematics published on GitHub under MIT license, and is available on Tindie for $29.95. ## Full article daily.dev links to this article rather than hosting it.
