About the project
An open 4-layer KiCad board that gives a computer its own phone line over USB-C: LTE data, SMS and voice calls with call audio on USB. Built around a Quectel EC25-EUX module and an RP2040.
Useful for
- Fabricate the board from the Gerbers and JLCPCB BOM to get an LTE modem with voice
- Send SMS and answer calls from a script via AT commands on the serial ports
- Use the RP2040 USB sound card to route call audio through a headset

Stars per day
Bars show stars per UTC day; the line is a moving average of available history. Gaps mean missing data, not zero growth. Today's bar is incomplete. Red marks spike days.
Why it’s trending
- Star-counter measurements on 2026-10-31 (UTC), 19:53–21:22: 6 → 13 stars (+7). This is the change over that interval.
- Estimated end-of-day forecast: about +8 stars, using observed gains and the previous day.
- The repository is 0 days old and already has 13 stars. With less than two weeks of history, there's no usual pace to compare the spike against yet.

Star trust
Growth looks organic: forks and discussion are in line with active projects, and stars arrive unevenly, the way people give them.
These are heuristics, not a verdict: we judge by the repository’s behavior, not by a list of stargazers.
