Libre Computer Tritium (ALL-H3-CC)
Tritium is Libre Computer’s Allwinner board in the Raspberry Pi 3 B+ footprint, funded on Kickstarter in January 2018. It comes in three versions with pin-compatible SoCs: the H2+ with 512 MB (IoT, 1080p HDMI), the H3 with 1 GB and the 64-bit H5 with 2 GB. Its four USB 2.0 ports each have their own SoC channel instead of sharing a hub. Libre Computer supports it with mainline Linux until 2047.
