It has GPIO buttons on the face and side for input, a single mono speaker, a 240x240 SPI controlled display, and a USB-C OTG port for power. The SoC includes 64MB of RAM and an SD card slot for booting. The SPI display is currently unsupported, as it will either require a new tinydrm driver or changes to the staging fbtft driver to support. I plan on working on a tinydrm driver to properly support it. There also may be a missing mux in the audio path that must be discovered and defined before audio will be fully working (internal speaker does not work yet, external headphones untested).
