## Blueprint

**Schematics published.** Built from the RAK3401 core (nRF52840) and RAK13302 1 W LoRa module (SX1262 + SKY66122 PA), each documented on docs.rakwireless.com with circuit-level schematic diagrams; no PCB source published, and no separate schematic exists for the assembled kit.

### Key parts

| Part | Role | Datasheet |
|---|---|---|
| Nordic nRF52840 | MCU (RAK3401 core) | https://www.mouser.com/new/nordic-semiconductor/nordic-nrf52840/ |
| Semtech SX1262 | LoRa transceiver (RAK13302) | https://www.semtech.com/products/wireless-rf/lora-connect/sx1262 |
| Skyworks SKY66122-11 | LoRa power amplifier (up to 1W/30dBm) | https://www.skyworksinc.com/en/Products/Amplifiers/SKY66122-11 |

_Notes:_ Verified module-level datasheet pages via WebFetch: both RAK3401 and RAK13302 pages contain embedded circuit-block schematic images (power path, SX1262 config, PA circuit, boost converter) but the pages state 'No downloads' for a PDF/source file. The RAK10724 starter-kit overview/quickstart pages give assembly info only, no kit-specific schematic.
