Official stock firmware releases for the T1Sim badge.
Open Tools > Firmware Update > T1Sim badge in a version of FreeWili GUI that includes this updater. The GUI downloads and validates the selected release automatically. Select your board, then press Update and verify. Keep USB connected until the board restarts. The updater preserves the internal data partition and microSD contents.
Download releases. Stable and Preview are separate channels; Preview builds are marked as GitHub prereleases. Read each release's verification notes before installing.
Manual recovery: enter the board's RP2350 BOOTSEL mode and copy the standalone UF2 asset to its recovery drive. Confirm the board model first: other RP2350 boards also expose this drive. These images are only for the T1Sim badge.
This repository contains firmware binaries, release manifests, documentation, and packaging tools. See RELEASE_FORMAT.md for publishing.
