Assembly
- Connect the Battery:Take the included battery and connect it to the PH1.25 battery header on the LoRa hat.
Attach the SMA Connector and Antenna:

- Screw in the antenna to the SMA connector.
Install the Raspberry Pi Pico W:
- Place the Raspberry Pi Pico W on top of the LoRa hat.
- Ensure that the pins are correctly aligned.
- Pay attention to the orientation: the USB port of the Raspberry Pi Pico W should be positioned away from the antenna.
Flashing The Software
The Web-Based Installer requires either Chrome or Edge browsers but is an excellent choice for quickly flashing devices.
- Plug in your device
- Visit flasher.meshtastic.org *requires Chrome or Edge browser
- For the device, we will go with Raspberry Pi Pico W
- Choose the latest stable version
- Click on Flash
The CLI Script is considered the "manual process" for flashing firmware. If the web-based flasher doesn't work, an alternative option is to use the CLI (Command Line Interface) script. While we won't cover it in detail in this guide, you can refer to the Meshtastic Guide for comprehensive instructions.
