RISC-V based HydraUSB3 board is open source and supports high-speed protocols
The HydraUSB3 V1 is a development kit that accommodates the WCH CH569 microcontroller. This device was designed to create projects that involve streaming or high speed protocols (i.e. SerDes and HSPI) via USB3.0.
As previously mentioned, the MCU compatible with this development kit is the WCH CH569 which is based on the 32-bit RISC-V3A core. According to the datasheet, this chip “integrates super-speed USB3.0 host and device controller (built-in PHY), GbE controller, dedicated high-speed SerDes controller (built-in PHY, can drive optical fiber directly), high-speed parallel interface (HSPI), digital video port (DVP), SD/EMMC interface controller and encryption/decryption module.”

Techbase offers Remote Raspberry Pi CM4 Program
Techbase is a Polish-based company tackling global chip shortage and supply chain issues with a remote platform to speed up development. As of now, the devices offered for remote access are the ModBerry 500 CM4 and the ClusBerry-2M.
The ModBerry 500 CM4 is an industrial computer based on the Raspberry Pi CM4 powered by the quad-core Cortex A72. This device can be highly customized with upgraded RAM, eMMC flash and other peripherals. LinuxGizmos covered this device last year, however the specs will also be listed at the end of the article for reference.
