Overview
This board provides a minimal interface around the RAK4630 module, exposing its programming and I/O lines on a header and powering it from a USB-C port. It is intended as a development and flashing carrier for the RAK4630.
Features
- RAK4630 module footprint (nRF52840 MCU + SX1262 LoRa radio)
- USB-C 2.0 receptacle for power and data
- TPD2EUSB30 USB ESD protection
- TLV62569DBV step-down DC/DC converter for the 3.3 V rail
- Reset push button
- Solder jumper for power-rail / option configuration
- 8-pin breakout header for GPIO / SWD / UART access
- Test points for key signals

Questions
How big is the Rak4630 interface PCB?
It measures 50.8 × 30.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rak4630 interface use?
27 parts, built around the RAK4630, TLV62569DBV, TPD2EUSB30DRT and UJ20-C-H-G-SMT-5-P16-TR. 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 Rak4630 interface KiCad files?
From the pashamray/rak4630_interface repository on GitHub, at the commit this page was made from: the board is hardware/kicad/rak4630_interface.kicad_pcb and its schematic hardware/kicad/rak4630_interface.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rak4630 interface 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).
