I saw a few tweets about this 5x5cm prototype SBC router, which might be interesting:

If it can eventually run OpenBSD I could picture using it as a cheap SBC to accelerate an Internet connection by prioritizing empty TCP ACK (scroll down and look at the two images) packets.
The specs from the tweets are:
RISC-V Router
5 cm x 5 cm
2 x Gigabit Ethernet (RTL8211F phys - RGMII)
2 x CAN2.0 up to 1Mbps
2 x USB2.0
MIPI-DSI/LVDS/RGB and uart, gpios,12bit gpadc
The D213ECV SoC appears to new from ArtInChip, so there is no information about it online (yet).
Someone in twitter has pointed to https://github.com/openhwgroup/cva6 as a possible source of the SoC. If this is true then the D213ECV is probably a 6-stage, single issue, in-order RISC-V CPU.
EDIT: I guess I should include a photo of the prototype(/?production?) board (from twitter):
