RISC-V Linux development board with the Allwinner D1-H C906 RISC-V 1GHz, 1GB DDR3, onboard 256MB SPI NAND flash and 32GB micro SD card with Fedora Linux installed, gigabit Ethernet, WiFi and Bluetooth, HDMI output and USB. This is a ready-to-go RISC-V Linux system, full specs at https://d1.docs.aw-ol.com/en/d1_dev. Note that this is a full Fedora/RISC-V image, not the cut-down Tina Linux that the Nezha normally comes with. In original box with manuals and cables.
Currently on TM but I get the feeling it's not the sort of thing people would expect to find on there so I'm mentioning it here, $150 for GZ members.
