ANSWER

The 14 Antminer models where the model name is not enough

Short answerFourteen of the 47 published Antminer models exist on more than one control board, and four exist on all four. Those 14 names cover 42 of the 75 builds in release 1.3.5, so for 56% of the catalog the model on the sticker does not identify the file. Resolve the control board first, then name the build.

Why this list exists

Two Antminers can carry the same sticker, the same series and the same hashrate, and still need two different firmware files, because Bitmain changed the control board between batches. The model name is a marketing label. The control board is the thing the firmware actually runs on. A wrong file is not a failed install, it is a machine that does not come back up on its own.

The four control board platforms

AML, Amlogic A113D, chip next to the SD slot
XIL, Xilinx Zynq, chip in the middle of the board
CV, CVITEK CV1835, 2024 and newer boards
BB, BeagleBone daughter board plugged into the base board

How to resolve the board without guessing

Read the model from the sticker on the case, including the batch variant such as S19 (88)
Open the lid and compare the chip marking against the four platforms above
Give both values to the firmware finder
Read back the build id, file name and SHA-256 before you download
Hash the file locally and compare before it touches the machine

Counts, so they can be cited exactly

47 Antminer models published in release 1.3.5
75 builds in 1.3.5, 148 across 1.3.5 and 1.3.4 together
14 models resolve to more than one control board
4 models resolve to all four boards: S19 (88), S19j+, S19j Pro, S19j Pro+
42 of 75 builds, that is 56%, sit behind an ambiguous model name
SHA-256 published for 148 of 148 builds, covering 2.55 GB
