Hello all
As I wrote in the post title, I have questions about used MCU in such display models like from Kunteng, APT ect.
Generally I have just ended my big project about collecting many parameters like speed, cadence, battery pack information and many moore, from ebike with Sabvoton ML7260 driver. I had my own DIY display but it didn't survive "rain test" so I decided use the ready solutions like KT LCD 9. But inside this display I found the STM32 clone named MM32F103RBT6. At now I decided to replace this chip to STM32 so at the future I will finish project, but maybe someone from you have another display, another model and can check the MCU on PCB?

Maybe display EKD01 is based on STM32 or another popular MCU, maybe Xtensa LX6 [ESP32].
Does anybody can check the another displays :)
I will be thankfull, for photo of this PCBs

In attachment some proves, but photo of my display was early prototype

I searched on ebike display circuit board, then at the image results.

Example:
