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.

The Open Source Autarkic (Eink) Laptop
But I don't know how to design at all, and RAM on its own is a lot harder to integrate into a board, and isn't as simple as soldering 8MB PSRAM on a Teensy pad. That said, this academic group did that with An Apollo3 MCU: https://github.com/tudssl/engage The Apollo4 will have 1.8MB SRAM, which I think will be more than a lot of these boards have https://ambiq.com/apollo4/ at much lower power. The Apollo3 Blue+ has 768K SRAM.

Minor changes and a name for my new board... Behold HUMMINGBIRD 32 (H32 for short).. A sub 200nA IQ sensor node with ESP32 & optional RFM9x module... waiting for prototypes before launching on groupgets!
Thanks for the analysis! I am not an engineer so I try to glean as much as I can from this so hopefully I can find the right components and discard the things that aren't needed. This board here used the same MCU in my link above: https://github.com/tudssl/engage so I am looking for ways to turn it into a solarpowered laptop with e-ink that doesn't shutoff/sleep every 10 seconds but can idle 24hrs using a few of these https://www.powerfilmsolar.com/products/electronic-component-solar-panels/indoor-light-series/ll200-2-4-75. I had considered the ESP-32WROVER with 8MB RAM but the PSRAM is not as low power as FRAM.

Tiny SliTaz port to ESP32-WROVER?
I became curious because this project ran a game on a 48mhz processor using FRAM: https://github.com/tudssl/engage
