README
README.md5G M.2 USB3 Interface Board
I’ve been experimenting with 5G cellular modules recently, and found that many of the M.2 break-out boards that run on just USB power (mostly designed for 4G modules) can’t supply the required current at the peaks during transmission. I decided to design my own in KiCad with dual-power input, Nano-SIM slot, and USB 3 to support the required data rates for 5G.
I'm using mine with a Quectel RM500Q-GL 5G module that I've previously blogged about. The design very much obeys the appnote recommendations for the RM500Q-GL module so use with that one especially should work fine.
Features
- Compact size, 90mm x 40mm board size; with 82mm x 32mm spaced M2.5 mounting holes
- USB 3.0 SuperSpeed for high 5G data rates
- Dual-power input.
- USB 3.0 B (not recommended for heavy data use, but fine for lower-end modules)
- 5-9V DC 5.5mm barrel jack (centre-positive)
- Fits both 52mm and 42mm M.2 B-Key modules
- Single 4FF Nano-SIM USIM slot
- Module reset button
- Module WWAN LED
- Power LED
- 5V 3-pin fan header
Stackup & BOM
4 layers. Standard FR4. ENIG recommended for easier soldering of the fine-pitch parts (M.2 connector & TPS82130SILR DC-DC converter)
BOM can be found in the bom/ directory. Currency is GBP. Total build cost (excluding non-special caps & resistors) is ~£15 in 10qty.

Questions
How big is the Usb3-ngff carrier PCB?
It measures 90 × 40 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Usb3-ngff carrier use?
62 parts, built around the MBRA340, SIM8060-6-1-14-00-A, KMR221GLFS and KUSBX-BS1N9-1-BL30. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Usb3-ngff carrier KiCad files?
From the themainframe/5g-m2-usb3-interface-pcb repository on GitHub, at the commit this page was made from: the board is usb3-ngff-carrier.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Usb3-ngff carrier design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
