It worked with the printer I reviewed here:
If Creality did another cool switcheroo for the board, it probably won’t work
Great review! Yup, at some point this year Creality changed the mainboard in the Smart, and started putting in the same one as the Smart Pro.
So you can load Smart Pro firmware on the currently sold Smarts, but the configs won’t work as there are differences in pinouts and probably a lot different in the daughter board on the gantry.
Anyone buying a Smart with the newer board (CR-FDM-v2.4.s1) has basically no non-stock firmware options at this point, until we have a working config for the steppers and sensors.
That’s my conclusion about the general situation anyway, after getting frustrated with how basic the Smart stock fw is, getting excited about your work with Klipper, and then back to square one because they did a board swap. 
…although, I’m still hoping someone will chime up here, telling us they have klipper fw running on the new boards! There are some hints about this in this thread, but nothing concrete, and no confirmations or denials so far…if anyone got klipper going on Smart with CR-FDM-v2.4.s1, please speak up!

I am working on this now…
This seems to be a very helpful lead at klipper issue pr 5621 which is focused on the Sermoon v1
Note the images of the board show an STM32F401…

nevermind… my board is CR-FDM-v2.5.S1_100 and is indeed a STM32F103

Despite trying to compile my own klipper.bin file multiple times, the power would not stay running…
I tried enable pin PA0/!PA0 etc with no luck
I found a google drive link which I cant post here with a working klipper bin file for CR10 Smart Pro for the sonic pad…
I will try to circle back to compiling after/if I get the rest of it working…
Hello. Can someone who has new cr10 smart board post the picture of cables connected to motherboard especialy where is z optical switch connected. My old board crc 2405v1.2 is not working so i want to put new board like in smart pro
Thanks
Hello, the Z optical pin is the PB2, but I can work in Marlin, comment if you can get it to work in Klipper.
Hello, So i have the onboard creality box flashed and the printer.cfg loaded, but I’m stuck as what I need to do next. I’m assuming I need to install fw to the printer itself, but not sure where to get it. Also do I need to change the wiring so klipper can see the printer?

# !CR-10 Smart
# printer_size: 300x300x400
# version: 3.6
# This file contains pin mappings for the Creality CR-10 Smart
# with a CR-FDM-v2.5.S1 board.
# To use this config, during "make menuconfig" select the STM32F103
# with a "64KiB bootloader" and serial (on USART1 PA10/PA9)
# Flash this firmware on the MCU by copying "out/klipper.bin" to an SD
# card and turning the printer on with the card inserted. The firmware
# filename must end in ".bin" and must not match the last filename
# that was flashed.
# The machine itself includes a small router that can run a Klipper
# frontend. You don't need to buy a single-board computer.
# See docs/Config_Reference.md for a description of parameters.

ohhh and this works fully for cr-10 smart with the new board ? in your description it does say correct…
i found another cr-10smart printer.cfg. but some pins are diffrient, even tho it’s also for the newer board CR-FDM-v2.5.S100
can you confirm it works ? kinda worried about diffrient pins on both probes and heater
i’m posting the other cfg i found on reddit (credit to the guy who made it)
