Question about Creality Ender 3 S1 Pro
Which motherboard is in it? STM32F401 or STM32F103? You can tell by the firmware version. The 1.0.x versions are STM32F103 and 3.0.x versions are STM32F401, Soo... which one is it? Thx
Helpful answer
In my case there was no way of telling it from the outside - I had to open it and check. Mine was 401
The one delivered to me late last year has F/W VER 2.0.8.15F4 and H/W VER CR-FDM-v2.5.S1_1
