Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

- My alpha Pico-based CH32V003 debug tool is ready for a few testers

Hardware/software to run RISC-V ASM?
VCC-GND Studio is about to launch similar boards based on CH32V307.
-
EPS32 but for wired Ethernet instead?
But if you're looking for RISC-V + integrated PHY, take a look at WCH's CH32V307 - just add magnetics, termination and an RJ45 jack and you've got 10BaseT.
-
MCU dev board with 5 UARTs?
Yes, English datasheets can be found - along with code examples, board schematics etc - at the openwch/ch32v307 Github repo.

Useful Tools and Resources for RISC-V development
More realistically, I DO think there's value for a terminal server that's just an ethernet connection (even one that's ancient) with some amount of programmability that's connected to 80 GPIO pins, some of which may be serial ports. I could imagine testing 1-2 Raspberry Pi-class with a bed of nails style test jig that confirms that all the GPIO, JTAG, and such are at least toggleable by sending synchronized signals to the BeagleBone/VisionFive/ESP32-C3/ whatever to confirm that all the I/O pins survived the fine wires from the wafer to the package plus all intervening PCB vias and soldering and so on. (Maybe you can't test board X with another board X because there's a different number of inputs and outputs.)
- The RISC-V MCU CH32V307 is a bad boy

New $10 Risc-V development board
looks to be IMAFC from the PDF on their github (https://github.com/openwch/ch32v307/blob/main/Datasheet/CH32V20x_30xDS0.PDF)

MCU dev board with 5 UARTs?
I started pulling together a docker build container; if you're interested let me know and I'll bump that up the priority list. It uses a custom GCC (8.2+) put together by MounRiver, based on SiFive's 2019.05.0 compiler release.
