JYETech DSO138mini(https://jyetech.com/dso138mini-oscilloscope-diy-kit/) is Oscilloscope DIY Kit.
This board is on STM32F103C8T6 and TFT LCD(320x240). So we can use Arduino for STM32.
- I suggest to develop using PlatformIO.
If you want to write a sketch only with a USB cable, you would install STM32duino bootloader.(It means Maple mini DFU bootloader).
