:::note
This is an earlier version of the T-Beam board, and due to changes in the design in subsequent iterations this board uses a specific firmware file different from the other T-Beam boards.

`firmware-tbeam0.7-1.x.x.bin` is the correct firmware. `firmware-tbeam-1.x.x.bin` is incompatible. For all other T-Beam boards `firmware-tbeam-1.x.x.bin` is the correct selection.
