NOTE:
Pay attention to the two versions of the motherboard for the S1, one is using a SoC STM32F1 and the other using a STM32F4:

* Ender 3 S1 printers that come with a firmware version 1.x.x have the STM32F1 chip.
* Ender 3 S1 printers that come with a firmware version 3.x.x have the STM32F4 chip.
* Check the version number on the STM32Fx chip itself to confirm your hardware version.
* Installing 1.x.x stock firmware or a compiled one to the target STM32F1 on STM32F4 mainboards might brick them! And vice-versa.

Where to put the firmware file on the SDCard:
* STM32F1 board: Put the *.bin file into the root folder.
* STM32F4 board: Put the *.bin file into a folder named STM32F4_UPDATE.
