Updating your boards

Once a board runs PropMesh, updates reach it over the mesh from the console. You shouldn’t need to plug it in again.

1. In Nodes & Channels, open the ↑ Firmware panel and choose Over the mesh.

2. Leave Image on Latest release. The console fetches the current firmware from this site on its own and shows ✓ latest release with the build name. Each board type gets its own image, so a mixed yard of DevKits and Feathers is fine.

3. Press Update all mesh boards, or Update on one board. Each board takes a few minutes, and the table shows how far along it is.

4. Update the bridge, which is the board your console is connected to, last, with Update (last).

Safe to interrupt

If an update stops partway because a board loses power or you close the laptop, the board shows paused, and Update resumes it. A board that can’t start the new firmware rolls back to the old one on its own.

Until the next release

Latest release needs two files this site only started publishing on 2026-10-14. If the panel says it couldn’t load the release, pick My own build instead, press from file, and choose the update file for your board type from Install the firmware.

My own build is for people building the firmware themselves: paste the URL from tools/ota_serve.py, or pick a .bin file.

Over WiFi is the faster option when your boards are in range of your home WiFi. Each board joins the network and downloads the update itself. It needs the image served from a computer on your network, which is covered in the project’s developer notes.
