# Koppar-AI/koppar-lte-modem

> 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.

- Magnitude: 3.3 out of 10 — Early signal
- Stars: 21 total · +15 stars measured 2026-10-31, 19:53–22:41 UTC
- Star trust: star growth looks organic
- Category: Hardware, IoT & robotics · License: CERN-OHL-P-2.0 · Created: 2026-10-31 · Last push: 2026-10-31

## 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

## Why it’s here

- Star-counter measurements on 2026-10-31 (UTC), 19:53–22:41: 6 → 21 stars (+15). This is the change over that interval.
- The repository is 0 days old and already has 21 stars. With less than two weeks of history, there's no usual pace to compare the spike against yet.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

## Numbers

- Forks: 0
- Issues and pull requests: 0
- Watchers: 0
- Average over the last week: 16 per day
- Usual pace: too little history (under two weeks)
- Stars in the last hour (measured): 6

## Stars per day, last 1 day (oldest → newest, today is partial)

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
