In each version directory, the following KiCAD assets can be found:\n - Symbols -\u003e `lib_sch/`\n - Footprints -\u003e `sim7600_breakout.pretty/`\n - 3D models -\u003e `3dmodels/`\n\n## Usage Pre-Requisites\n\n- A fully assembled lamemakes SIM7600 Breakout Board\n- Antennas for respective purposes\n    - 50Ω passive LTE/4G w/ U.FL connector\n    - 50Ω **active/powered** GPS/GNSS w/ U.FL connector)\n- An activated Nano SIM card\n    - Carrier _shouldn't_ matter, see **IMEI** section\n- Device that supports some form of serial communication\n    - UART, I2C, and SPI are all supported.\n- _(Optional)_ Wired headphones, ideally with about a 35Ω impedence.\n\n## Usage \n\nThe breakout board can be initialized by connecting +3.3v to the +3v3 pin, and ground to the GND pin. Then, turn the module on by pulling the PKEY HIGH.\n\n## Pics\n\n*Schematic*\n![SIM7600 Breakout Board Schematic](pics/SIM7600_Breakout.svg)\n\n*PCB*\n![SIM7600 Breakout Board Schematic](pics/SIM7600_Breakout-pcb.svg)\n\n## Notes\n\n- **Be a good neighbor on the RF spectrum!** There is certainly a lot of grey area when it comes to legality and LTE/carrier service, so be conscientious - stay within local law. \n- Contribute! This is my first real RF/4G PCB, so if you see somewhere that could be improved feel free to raise an issue or put up a PR.\n- As this is assembled and tinkered with, this README will be immensely updated for better usage instructions.\n- It's clear the language barrier is an issue when it comes to the SIM7600 docs, but these resources helped me out a ton:\n    - [Xinyuan LilyGO/T](https://github.com/Xinyuan-LilyGO/T-SIM7600X)\n    - [CircuitMess Ringo](https://github.com/CircuitMess/CircuitMess-Ringo) \u003c- such a cool project, look to do something very similar moving forward\n    - [Waveshare SIM7600 HAT docs](https://www.waveshare.com/wiki/SIM7600E-H_4G_HAT)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flamemakes%2Fsim7600-breakout","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Flamemakes%2Fsim7600-breakout","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flamemakes%2Fsim7600-breakout/lists"}
