## Blueprint

**Closed design.** No schematic or PCB source is published for the (base) Wio Tracker L1; only a mechanical outline drawing and regulatory filings are public.

### Design files

- enclosure: [Board outline drawing (DXF)](https://files.seeedstudio.com/wiki/SenseCAP/Meshtastic/Wio%20Tracker%20L1%20outline.dxf) (DXF)

### Key parts

| Part | Role | Datasheet |
|---|---|---|
| Nordic nRF52840 | MCU + BLE radio | https://www.nordicsemi.com/products/nrf52840 |
| Semtech SX1262 | Sub-GHz LoRa transceiver (862-930 MHz) | https://www.semtech.com/products/wireless-rf/lora-connect/sx1262 |
| Quectel L76K | GNSS/GPS receiver | https://www.quectel.com/product/gnss-l76/ |

_Notes:_ Checked the Seeed wiki page, product page, and Zephyr board docs; none link a schematic for the base L1. A KiCad-exported schematic PDF IS public for the related 'Wio Tracker L1 Pro' SKU (files.seeedstudio.com/wiki/SenseCAP/Meshtastic/Wio_Tracker_L1_Pro_SCH_PDF.pdf), but that adds an OLED/enclosure/battery and is a different product, so it isn't listed as this device's own file.
